FAQ

  • How do I pair the headphones (single or multiple) to the transmitter?

    To pair the headphones (single or multiple) of the RS 160 or RS 170 or RS 180 to the transmitter please follow these steps:

    Step 1: Start with both the headphones and the transmitter unit off. You should see no lights blinking when the components are off. NOTE: Press and hold the power button for 1 second to turn the components off.

    Step 2: Simultaneously press and hold the power button on the transmitter and the power button on the headphones for about 8 seconds until you see rapid blinking of the lights (about twice a second). Once you see rapid blinking you may release both buttons. Wait for the rapid flashing (about twice a second) to slow down to slow flashing (about once every five seconds) which will take about 30 seconds. NOTE: If you are connected to an audio source that is turned on at this point you would hear audio in the headphones.

    Step 3: Turn the headphones and transmitter off.

    NOTE: If you have a second, third, or fourth set of headphones that you want to link to the same transmitter then repeat steps 1 and 2 and 3 with each pair of headphone doing one pair at a time and turning both the transmitter and headphones off after the pairing process.

    If you are plan to use more than one set of headphones on the same transmitter at the same time then you will need to put the transmitter into the "multi mode" before you can hear sound out of all the headphones at the same time. To enter multi mode press the power button on the transmitter to turn it on and then press the power button on the transmitter once more to enter the "multi mode". When the transmitter is first turned on you will notice that the light blinks once every five seconds and after entering multi mode and a second headset is turned on you will notice the power light on the transmitter blinks twice every five (5) seconds to indicate the "multi mode".

  • How do I set up the RS 160 wireless headphones?

    Please check out our Set Up Tutorial video: RS 160

    LINK: (https://www.youtube.com/watch?v=NenAI9dE7Q4)

    OVERVIEW OF SET UP STEPS
    Step 1: Remove all components from the box. These will include transmitter/charging station, headphones, power cable, audio cable, batteries and adapters.
    Step 2: Insert the batteries into the headphones. 
    Step 3: Use the power cable to connect the transmitter/charger to an electrical outlet. Alternatively the transmitter can be powered by two (2) AA batteries.
    Step 4: Charge the headphones. The charge indicator light will illuminate to indicate charging. NOTE: The batteries in the headphones should be charged for 16 hours initially.
    Step 5: Use the audio cable connect the transmitter/charger to the audio OUTPUT on the audio source. NOTE: Depending on your audio source you may be connecting into a 3.5mm headphone jack, red and white RCA audio outputs or a digital output. 
    Step 6: Turn on your audio source.
    Step 7: Turn on your transmitter. The LED on the transmitter will illuminate and start blinking.
    Step 8: Turn on your headphones. The LED on the transmitter will illuminate and start blinking.
    Step 9: Wait 30-60 seconds for the wireless signal between the headphones and transmitter to be established and then you will have audio.

    NOTE: The RS 160 & RS 170 & RS 180 models do not include a digital connection. If you need to connect to a digital audio output then you will need a digital to analog decoder like the OREI DA 34.

  • What do I do if my unit suddenly stopped working?

    In a situation where a unit that has been functioning correctly has suddenly stopped for no apparent reason the issue is likely an internal electronics glitch caused by a power surge. To resolve this issue an internal electronics reset is required.
    Disconnect the transmitter (base station) from both the audio source and the power source and at the same time remove the batteries from the headset. Leave the system disconnected from power and the batteries out of the headset for 15 minutes. This gives the internal electronics unit a chance to reset back to factory settings.
    After the internal electronics reset the wireless headphones will need to be re-paired to the transmitter. The pairing process for the RS 160, RS 170 & RS 180 wireless headphones is as follows:

    Step 1: Start with both the headphones and transmitter turned off (ie: no blinking lights).
    Step 2: Pair the transmitter and headphone together. (This is done by simultaneously pressing and holding the power button on both the transmitter and headphones for about 7 seconds. The lights will blink rapidly - about twice a second.)
    Step 3: The headphones are now paired with the transmitter.

    NOTE: To pair additional headsets turn off all components and repeat the steps listed above.
    Please check out this "How To" video (http://www.youtube.com/watch?v=brFXknPUjPc) to see the process in real time.

    NOTE: If the GREEN light doesn't come on or comes on and then goes away when the transmitter is plugged into both a power source and an audio source then it means that the audio signal is is too low (or not getting to the transmitter at all). The transmitter needs a nice, strong signal to work with and if the audio signal is very weak (or non-existent) the internal electronics will shut off within 5 minutes to conserve battery life. If this is the case then the signal level needs to be increased before reaching the transmitter. This can be accomplished by turning up your source on variable-level outputs (TV Volume) or by increasing the signal from a fixed-level output (increasing the output level to the audio output jacks which is done through the TV set up options). Try increasing it in small increments to prevent overload which results in distortion. Also check to see that you are connected to outputs and not inputs.
    If there is no way to increase the audio signal and hence the GREEN light does not come on and stay on on the transmitter it would be recommended to try to connect to a set top box (cable box, DVR, HD receiver, etc) through its audio outputs or connect through a headphone plug in order to get a stronger signal.

    NOTE: After the reset the LED that indicates charging may be out of sync with the internal electronics so it may not act in the manner that should be expected (ie: doesn't come on, doesn't turn off, comes on briefly and turns off). This is not an issue and will resolve itself after a few days of using the headphones and charging the headphones and using the headphones. It is a matter of the LED and internal electronics getting back in sync.

  • What is the difference between RS 160 and TR 160 and HDR 160?

    The RS 160 is the model number refers to the complete wireless headphone system. This system consists of the transmitter (TR 160) and headphones (HDR 160).



    RS 160 ( #502873 )
  • What is the input impedance of the RS 160 transmitter?

    The input impedance of the 3.5 mm audio input jack on the transmitter depends on the setting of the attenuation switch on the back of the transmitter.
    If the attenuation switch is set to -8 dB it is about 12 kohm. If the attenuation switch is set to 0 dB it is about 80 kohm for the RS 160.



    RS 160 ( #502873 )
  • Why are my headphones are not charging (intermittent charging light)?

    On the front of the transmitter there is the battery charging indicator light and when the battery is charging this indicator will light up AMBER. NOTE: Once the battery is charged the AMBER light will go out.

    The batteries are initially charged at manufacture but Sennheiser has no way of knowing how much the batteries will be depleted from the time they leave the factory to the time a customer sets them up so we recommend the 16 hour charge to be on the safe side. Initially the charge may be quite short but once you start using the headphones the charging process will take longer and the charge light will stay on for longer. 

    Initially when the headphones are brand new the charging light on the transmitter may appear intermittently. Usually it will take a few charging cycles (ie: using the headphones and charging the headphones) for the charging electronics in the headphones and transmitter to get into sync and the issue will resolve itself.

    When the headphones have been in use for awhile occasionally the headphones can develop an electrical glitch where the LED indicator light and the internal electronics get out of sync so the light will either not come on as expected or remain lit after fully charging or be intermittent. This may happen when products are disconnected from power for a period of time, the batteries have recently been changed or a power surge has occurred. It usually takes a few charging cycles (ie: using the headphones for a few hours and then charging them) for the lights and internal electronics to sync up. If you are experiencing this issue simply use the headphones and charge the headphones in a normal manner and the indicator light and internal electronics will get into sync and the issue will resolve itself.

  • 무선 헤드폰에서 어떻게 최상의 전송 대역을 얻을 수 있습니까?
    무선 헤드폰의 전송 대역은 대부분 각 무선 헤드폰 제품이 사용하는 무선 기술에 의해 결정됩니다. 또한, 무선 신호 전송 대역에 영향을 줄 수 있는 여러 외부 요인 (장애물, 오디오 신호 강도, 무선 신호 폭주 등)이 영향을 미칩니다.

    장애물은 무선 신호의 전송 범위에 영향을 줄 수 있는 주요 요인입니다. 무선 신호 (적외선 신호 제외)는 벽과 같은 장애물을 통과할 수 있지만 결국 대역은 이러한 장애물을 통과할 때 마다 분명 영향을 받게 되고, 장애물의 밀도가 커질수록 무선 신호에 미치는 영향력은 더 커집니다. 예를 들어, 유리창을 통과하는 신호는 별로 영향을 받지 않겠지만 콘크리트 벽을 통과하는 신호는 훨씬 더 약해집니다. 결국 장애물이 없는 탁 트인 공간에서 최상의 전송 범위를 얻을 수 있습니다.

    오디오 소스가 헤드폰으로 전송하는 오디오 신호 또한 중요합니다. 송신기로 들어가는 오디오 신호가 약하면 결국 송신기가 내보낼 수 있는 오디오 신호 또한 약해지게 됩니다. 따라서 오디오 소스가 최상의 신호를 출력하고 있는지를 확인해 보십시오.

  • Why is the sound of my Assistive Listening System slightly behind the video image or speaker sound?

    The issue where the sound of the headphones is slightly behind the image on the TV or audio from the speakers could be caused by the latency of the headphones (the time it takes to transmit sound via a wireless signal) or it could be the device that the headphones are connected into and how that device is outputting the audio signal that is the issue.

    Latency occurs in all wireless headphones however the technology being used to create the wireless signal does affect how much latency is caused. For example a Radio Frequency (RF) model (like the Set 840) has a latency of approximately 3 m/s whereas a KLEER digital model (like the RS 160/RS 170/RS 180) has a latency of approximately 45 m/s. Usually the delay (even at the 45 m/s level) is not discernible and hence goes unnoticed.

    The component that the headphones are connected to will also affect this issue and could make the inherent latency more obvious. For example if a TV outputs sound to it's own speakers slightly faster than it outputs sound to the audio output jacks that the headphones are connected to then that would mean that there is a delay in the audio getting to the headphones on top of the latency of the headphones so the difference between audio and image would be more obvious. 

    To overcome latency issues sometimes the component that the headphones are connected into will have a latency adjustment which can be used to adjust the component to match up with the headphones. If the component does not have a latency adjustment then a second option would be to connect the headphones directly to the audio source (ie: cable box, DVD player, etc) so that the headphones get the audio signal slightly before the TV and hence the latency factor compensates for getting the audio signal before the TV.

  • RF (Radio Frequency)

    RF is the acronym for Radio Frequency.

    Radio Frequency is a type of wireless signal.

    Radio Frequency signals have the ability to pass through most obstacles (like walls).

  • Can different wireless headphones be used with different transmitters?

    The different wireless headphone models utilize different signal transmission technologies so the compatibility and interchangeability of the different wireless headphone models is dependent on the specific wireless headphone models in question. Please review the chart below for compatibility guidelines.

    NOTE: The special features of the various models are not applicable if you interchange models. For example if you take a set of headphones from one system (like the HDR 180 headphones from the RS 180 system) and pair it with a different system (like the RS 170) the headphones will provide  audio however the headphones will not have the additional features (like Surround Sound) because the headphones do not have the supporting internal electronics.



    RS 160 ( #502873 )
  • Can I use wireless headphones for performance applications or music practice?

    Our wireless headphones are designed for home A/V use (like TV watching, music listening, etc) not music performance and hence we do not recommend out wireless headphones for music performance applications. The reason for this is that all wireless devices have some form of latency (ie: the time it takes for audio to be transmitted wirelessly). The latency of wireless headphones is fine for home A/V use but the latency is too great for performance use.

    You would want something like EW 300 IEM G3 to go wireless with low latency, low noise and an acceptable input-dynamic range for performance applications.

  • How do I get sound from BOTH the TV and headphones at the same time?

    Having sound from BOTH the TV and the headphones at the same time is actually determined by how the headphones are connected to the audio source. Generally speaking there are a couple of ways of creating these connections which are:

    1) If a set top box (cable box, DVR, etc) is in use look for audio output jacks on this device and connect the headphones to the set top box to allow for independent operation of TV speakers and headphones.

    2) Check the TV manual/set up guide for an option that allows the TV to operate the speakers and audio output jacks independently (ie: fixed output) to allow for independent operation of TV speakers and headphones and connect into the audio output of the TV.

    NOTE: If you have a dedicated headphone jack and use that connection it automatically cuts sound to the TV speakers.

  • How do I get sound ONLY from the headphones and not the speakers?

    Having sound ONLY from the headphones and not the TV is actually determined by how the headphones are connected to the audio source. Generally speaking there are a couple of ways of creating this type of connection which are:

    1) Connect the headphones to a dedicated headphone jack which will usually automatically route sound from the TV speakers to the headphone jack and hence audio is only coming out of the headphone jack.

    2) If a set top box (cable box, DVR, etc) is in use look for audio output jacks on this device and connect the headphones to the set top box to allow for independent operation of TV speakers and headphones and hence the TV volume can be turned down or muted.

    3) Check the TV manual/set up guide for an option that allows the TV to operate the speakers and audio output jacks independently (ie: fixed output) to allow for independent operation of TV speakers and headphones and hence the TV volume can be turned down or muted.

  • What are the basic differences between the different wireless headphone models?

    Sennheiser offers a range of wireless headset options that utilize a variety of audio transmission signals (including Radio Frequency and Digital Audio Signals) and both on ear and around the ear models to suit different wearing preferences.
    These wireless headphone systems can be connected via a 3.5 mm plug into a dedicated headphone jack (which will often cut sound to the external speakers) OR to the RED & WHITE RCA audio output jacks (often found on the back of the TV, cable box, receiver, DVR, etc) and when connected in this manner they will allow for operation of both the headphones and the external speakers. All models offer unique functions yet will be able to provide an excellent listening experience and personal preference will play a large part in selection.
    Our range of wireless headphones can be seen on our website (http://en-us.sennheiser.com/wireless-tv-headphones).
    NOTE: We do NOT recommend Bluetooth headsets for applications like TV watching as the latency (time it takes for a Bluetooth signal to be transmitted) that is inherent to all Bluetooth devices causes the audio to be out of sync with the video.
    A few quick differences to keep in mind when choosing:

  • What headphones can connect directly into a optical audio output?

    The number of wireless headphones (regardless of manufacturer) that will connect directly to a optical audio output is actually quite limited. The Sennheiser RS 175, RS 185 and RS 195 Wireless Headphones have the ability to connect directly to a digital optical output that is outputting a PCM signal.

    The alternate way to connect to a digital output is to use a digital to analog decoder which will take the digital signal and change it into an analog signal. When using a digital to analog decoder any analog headphones have the ability to be connected to a digital output.

    NOTE: The Digital to Analog Decoder we recommend is the OREI DA 34 as it is a good quality component that not too expensive but does not compromise the audio quality.

  • What is the wireless signal range of wireless headphones?

    As an industry standard the range of wireless headphones is measured "line of sight" (headphones from transmitter) as it is the only way for all manufacturers to measure the range in an equal manner.

    The effective wireless signal transmission range (ie: how far the headphones can get from the transmitter) will vary from product to product and is determined by the type of wireless transmission signal being used by the individual wireless headphone system. 

    The effective wireless signal transmission range will also be affected by external factors like obstacles, audio signal strength, wireless signal congestion, etc.

  • Why do I only hear sound from one of my audio sources?

    In a situation that where there are multiple audio components (ie: cable box, DVD, player, etc) connected and the headphones are only receiving sound from one of the audio components likely indicates that one of two scenarios is occurring.

    SCENARIO ONE
    The transmitter is connected directly into an external audio component (like the cable box) and hence can only get sound from that component. To get sound from a different external component the headphones would need to be disconnect from the original external device and connect to the other external component directly.

    A solution to avoid having to unplug from one component and plug into the other component all the time you could use an AV switching box to create a hub where all the external components can be connected into one place. The hub will then provide outputs to run audio to the TV and audio to the headphones as well.

    NOTE: An analog version of an AV Hub can be seen here: (http://www.amazon.com/Cables-To-Go-28750-Composite/dp/B0032ANC8M/ref=sr_1_1?ie=UTF8&qid=1393521908&sr=8-1&keywords=Cables+to+go+28750). 

    NOTE: A HDMI version of an AV Hub can be seen here: (http://www.amazon.com/Monoprice-Matrix-Switch-Splitter-Analog/dp/B004264PT0/ref=sr_1_3?s=electronics&ie=UTF8&qid=1372360465&sr=1-3&keywords=hdmi+rca+switch).

    SCENARIO TWO
    All of the external audio components are connected directly into a device (TV, Receiver, etc) however the devices are utilizing different types of audio signal (analog, digital, HDMI, etc) and the device that the headphones are connected to can only output some of these signals in a format that the headphones can utilize. The headphones are designed to use an analog signal so this is the type of signal that the device needs to output for the headphones to use.

    The solutions that could be used here would be to try an get all the external audio components connected using the same type of audio signal and utilize something like the AV Hub mentioned above. Alternatively a component like a Digital to Analog Decoder or Digital Audio Decoder which will accept different forms of audio signals (including multi-audio stream signals like HDMI) and convert the signals back to analog for the headphones to use could also be utilized.

    NOTE: A couple of the versions of the Digital to Analog Decoder are as follows: 
    - GEFEN Digital Audio Decoder (http://www.amazon.com/Gefen-GTV-DD-2-AA- Digital-Audio-Decoder/dp/B0021QBIBQ/ref=sr_1_2?ie=UTF8&qid=1393427713&sr=8-2&keywords=GEFEN+digital+to+analog+decoder)

    - OREI Digital to Analog Audio Decoder (http://www.amazon.com/Orei-DA34-Digital-5-1-Channel-Headphone/dp/B008EPW7O0/ref=sr_1_2?ie=UTF8&qid=1393427822&sr=8-2&keywords=OREI+da+34)

  • Why don't all headphones have a digital/optical connection or include a digital converter?

    Many of the older wireless headphones manufactured by Sennheiser were designed before the digital/optical connection became as common as it is today and up until quite recently most audio devices had both RCA outputs and digital/optical outputs hence the headphones were able to be connected directly.

    It is not possible to retrofit older Sennheiser models to have a digital audio input as the internal electronics are designed for an analog connection/signal not a digital connection/signal. NOTE: Newer wireless headphone models (like the RS 175, RS 185 and RS 195) do have optical audio connections.

    Since a digital to analog converter/decoder is not required for all applications it is not practical (and in fact would be cost prohibitive) to include this kind of a component with all older headphone models. Instead if a digital to analog decoder is needed for an individual set up it would be purchased as an aftermarket accessory. A good quality digital to analog decoder is the OREI DA 34.

  • Why don't I get audio from all sources (Netflix, Apple TV, Amazon FireStick, etc)?

    Audio coming from certain content providers or devices (Netflix, Roku, Apple TV etc.) typically use an advanced digital audio signal such as HDMI or advanced Dolby audio. These cannot be translated into analog or PCM by most television software and so the signal is not passed through into the headphones. As a result you may get silence or audio from a different source like your cable box.

    In order to resolve this, you will you will need to change the audio output format in the app or device to PCM (may be in the smart hub on some TVs) or you will need a digital to analog decoder. The Digital to Analog Decoder will take the advanced digital signal and decode it into an analog signal that your headphones can utilize.

    You will not lose audio quality as the digital signal is a carrier signal only. Any audio you hear from your TV speakers, sound bar or headphones is an analog signal. The digital signal is translated by the TV, receiver or other device by the time it reaches the transducers. The only difference is where the audio signal is translated.

    If your digital optical output is not in use we recommend the OREI DA34. The OREI DA 34 can be seen here: (http://www.amazon.com/Orei-DA34-Digital-5-1-Channel-Headphone/dp/B008EPW7O0/ref=sr_1_1?ie=UTF8&qid=1407330599&sr=8-1&keywords=OREI+DA+34).

    If the digital optical output is already being used by a device like a sound bar you will want the J-TECHDigital to Analog Decoder because it offers both an analog output for the headphones to use and an optical output for the soundbar (or other device) to use. The J-TECH can be seen here: (http://www.amazon.com/J-Tech-Digital-JTDDBSW0301-Decoder-5-1-Channel/dp/B00L3OZK1G/ref=sr_1_1?ie=UTF8&qid=1428599714&sr=8-1&keywords=jtech+digital+to+analog+decoder).

    Please bear in mind that we recommend these specific devices because we have tested them and know that they work. We do not recommend digital to analog CONVERTERS (a different device entirely) because they cannot translate the more complex digital audio signals.

    NOTE: We do suggest looking at your TV's documentation to make sure that there are no design features that prevent certain digital signals (like HDMI signals) from being output through the Digital Optical output before purchase. It is possible for this feature to exist but exceedingly rare so for most applications the Digital to Analog DECODER is the optimum solution.

  • Why do the speakers shut off when I connect my Wireless Headphones to the headphone port?

    A connection to the headphone jack of any audio component (ie: TV, A/V receiver, computer, etc) will automatically disable the speakers.

    If you need the speakers active so others can be enjoying the same audio we recommend connecting your headphones to the audio outputs (ie: RCA outputs, digital optical audio output, digital coaxial audio out, etc) of the audio component rather than the headphone output.

  • Why is the headphone sound slightly behind the video image or speaker sound?

    The issue where the sound of the headphones is slightly behind the image on the TV or audio from the speakers could be caused by the latency of the headphones (the time it takes to transmit sound via a wireless signal) or it could be the device that the headphones are connected into and how that device is outputting the audio signal that is the issue.

    Latency occurs in all wireless headphones however the technology being used to create the wireless signal does affect how much latency is caused. For example a Radio Frequency (RF) model (like the RS 120) has a latency of approximately 1 m/s whereas a KLEER digital model (like the RS 160/RS 170/RS 180) has a latency of approximately 45 m/s. Usually the delay (even at the 45 m/s level) is not discernible and hence goes unnoticed.

    The component that the headphones are connected to will also affect this issue and could make the inherent latency more obvious. For example if a TV outputs sound to it's own speakers slightly faster than it outputs sound to the audio output jacks that the headphones are connected to then that would mean that there is a delay in the audio getting to the headphones on top of the latency of the headphones so the difference between audio and image would be more obvious.

    To overcome latency issues sometimes the component that the headphones are connected into will have a latency adjustment which can be used to adjust the component to match up with the headphones. If the component does not have a latency adjustment then a second option would be to connect the headphones directly to the audio source (ie: cable box, DVD player, etc) so that the headphones get the audio signal slightly before the TV and hence the latency factor compensates for getting the audio signal before the TV.
