    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.
    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 headphones which in turn will turn on your transmitter. The LED on the headphones will illuminate and start blinking and the LED on the transmitter will light up and remain solid.
    Step 8: Wait 30-60 seconds for the wireless signal between the headphones and transmitter to be established and then you will have audio.

    NOTE: If connecting to a digital output make sure that the audio device is set to output a PCM or stereo signal.

  • Why do I hear an "echo" in the RS 185 headphones?

    The RS 185 headphones are "open aire" headphones which means that they allow sound in and out of the headphones. The headphones are designed like this to provide a more expansive sound scape and more nuance to the audio.
    The "echo" that is sometimes experienced is caused because the same sound (ie the sound through the headphones and the other speakers) is being heard twice at slightly different times.
    To resolve this issue there are a couple of options you can try:
    1) Turn the volume in the headphones up until it covers the sound from the other speaker and eliminates the echo.
    2) Turn the sound from the other speakers down until it gets low enough that the volume through the headphones is stronger than the sound from the other speakers and hence the headphones hide the echo.
    NOTE: Sometimes a combination of option one and option two are needed to achieve the desired results.

  • What do I do if my Assistive Listening System suddenly stopped working?

    In a situation where a unit that has been functioning correctly has suddenly stopped functioning 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 reset period reconnect the system to power and put the batteries back in the headset and test the system.

  • What is the wireless signal range of a wireless Assistive Listening System?

    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 (Infrared, radio frequency, etc) 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 experience Static/Hum/Hiss when using an Infrared Assistive Listening System?

    Typically a static/hum/hissing sound in the infrared headset is caused by one of the following events: 

    1) One of the RCA cables (red/white) is connected into an input rather than an output or the 3.5 mm connection has been plugged into a digital output rather than an analog output. To resolution is to make sure the audio cable is connected into analog audio outputs.

    2) There is some form of interference with the infrared beam of light from an external source (ie: a lamp or other form of light is disrupting the infrared light). The resolution is to remove this external interference. NOTE: If the unit is connected to an LED or plasma TV the light from the screen can actually be causing the interference and we would recommend switching to a radio frequency (RF) model rather than use an infrared model.

    3) The hiss is being created by the audio connections themselves through a faulty connection. The resolution is to try the unit on a separate independent audio source (like a cable box, DVD player, iPad, stereo, etc). If the unit works correctly on the new audio source you can then determine that the issue lies with the original audio connections and new connections with the original audio source need to be established. NOTE: For testing purposes we would recommend connecting directly to the audio source with the 3.5 mm connection on the audio cable as it is possible that a faulty 3.5 mm to RCA adapter could cause the issue.

    4) The audio signal itself is corrupted and the hiss is actually part of the audio signal. This typically occurs when a cable signal is involved. The resolution is to call the cable company and request that the audio signal is reset.

  • Why do my speakers shut off when I connect my Assistive Listening System to the headphone output?

    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 Assistive Listening System to the audio outputs (ie: RCA, optical output, digital audio out, etc) of the audio component.



    RS 185 ( #505564 )
  • 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.

  • 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.



    RS 185 ( #505564 )
  • 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:

  • 무선 신호 (또는 WiFi) 간섭이 있을 때 어떻게 해야 합니까?
    디지털 전송 신호를 사용하는 무선 헤드폰은 다른 무선 기기 (WiFi 라우터, 무선 프린터 등)와 마찬가지로 비공식 2.4 Ghz 대역에서 작동하며 작동 가능한 특정 주파수 대역이 있습니다. 무선 헤드폰은 로컬 무선 신호 환경을 스캔한 다음 지정된 범위 내에서 사용하지 않는 주파수를 자동으로 선택합니다. 따라서 다른 무선 기기와 충돌 없이 함께 사용이 가능합니다.

    일반적으로 WiFi 라우터의 대역폭은 헤드폰의 대역폭보다 크며 실제로 더 큰 대역입니다. 대부분의 경우에는 두 신호가 서로 떨어져 있어서 특별한 문제가 발생하지 않습니다. 하지만 WiFi 라우터가 헤드폰이 사용하는 대역폭에서 신호를 설정하면 두 신호가 서로 엉켜 문제가 생길 수 있습니다. 상황에 따라서 라우터 자체 스위치를 사용해서 수동으로 WiFi 라우터 주파수를 변경할 수 있습니다.

    WiFi 라우터를 수동으로 변경할 수 없는 경우, 헤드폰과 WiFi 라우터를 꺼서 간단하게 해결할 수 있습니다. 헤드폰을 켜고 15분 동안 작동시켜 신호를 잡은 후 WiFi 라우터를 켭니다. WiFi 라우터는 헤드폰의 신호를 감지하고 다른 곳에서 신호를 설정하게 되어 두 장치가 서로 간섭하지 않고 작동하게 됩니다. 참고: 한 번 설정된 신호 체계는 장치가 꺼져있어도 계속 유지됩니다.

    위의 방법으로도 문제가 해결되지 않는 경우에는 혼잡한 무선 환경이 원인이 될 수 있습니다. 이를 해결하려면 일부 무선 신호를 환경에서 제거해야 합니다. 예를 들어, 무선 프린터가 켜져 있으면 무선 신호 혼잡을 일으킬 수 있는 무선 신호가 생성됩니다. 따라서 혼잡을 줄이고 헤드폰이나 무선 기기가 작동할 수 있도록 프린터를 사용하지 않을 경우에는 꺼두는게 좋습니다.

  • 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.

  • 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.
