Sennheiser Wireless Headphone Stops transmitting signal

I have my headphones on with the transmitter plugged into my computer. It works for approximately 15 minutes before the transmitter stops transmitting a signal, the green light (on/off) goes blank and all i hear is a loud static sound.

    Identical problem. Is there a solution?

  • gnewman313 Jan 29, 2009

    Same problem but only about 10 minutes. Unplugging from the sound source solves it each time, but only for a few minutes.

    same as above: works fine for 10-15 minutes then loud static.

    Sennhieser headphones rs110 series. Headphones work great however for no apparent reason the transmitter will power off for anywhere from 5 to 45 minutes. When it comes back on it may stay on for several hours and then simply turn itself off. When it does come back on it will stay on for 5 minutes to several hours or only 5 to 10 minutes. Any ideas from anyone would be greatly appreciated since when the trans unit goes off the static is ear shattering.

    After reading this response and another that said check the connection of the transmitter (I had tried everything else - connections, volume) I unplugged the base signal cable and simply plugged it back in AND IT WORKED. No explanation why it happened in the first place - I have no kids, no pets, I went to bed one night and it was working - turned everything on the next day and the headphones weren't working. NOW THEY WORK. Base connection wasn't loose - I jus unplugged it and plugged it in again. GOOD LUCK!!! Joe

I had the same problem when I plugged it into a new HDTV. The problem was that the sound on the TV was set too low. The transmitter has a feature that automatically turns off when the signal is off or too low. Try turning up the TV volume to a high/higher level and it should solve your problem. Using the headphone jack with the white input allows you to use the headphones while bypassing the TV speakers.

Unfortunately these headphones have a “feature” that shuts them off after a set amount of time has passed. If no audio signal is detected.. after x number of minutes.. off they go.

A great feature for extending battery life.. a poor feature when using with sources that often have long pauses between signal output.. like using with a PC.. Often when listening to music while working on a document.. the music ends.. and a long pause ensues.. and the headphones turn off.

You need to turn them on and off again when you are sure an active audio signal is being sent to the base unit.

There is no workaround..

Since your problem doesn’t state they quit working during listening.. the above answer is all I have for now.

Other obvious things to check.. batteries.. and connections.. especially the connection on the base unit.

Best of luck

I can't believe anyone would design a pair of headphones with an "automatic switch off" without giving the option to turn the "automatic switch off" off.

    I am thinking about contacting the company if I cannot get a workaround... my wife bought two pairs of these headphones as a birthday gift to me to help me study, and the delay is an absolute nightmare... I basically have gotten that ringing in my ear about 4 times when the loud static comes on... It is insane.

I'm sure there is a way of doing it for a pc using a batch file or something but I'm not too up on my pc programming anymore..

Hope it helps..

Sennheiser HDR120 - missing transmitter / alternative OR replacement?

The system is working in the 860 Mhz range, so not that common. Most of the time it is cheaper to by a complete new system then to tray to buy components. Just keep looking in the thrift stores you find a transmitter for this headphone for a good price.

A2dp pairing problems

The Victsing unit states that it is a receiver. This will receive the wireless signal from a device and output sound through the headphone jack. A bluetooth transmitter would input sound into the headphone jack from your tv or other source and transmit the signal over bluetooth to a paired receiver. Two of the same type of unit will not pair with each other.

Set up the transmitter. Wireless headphones rely on a transmitter that sends audio via infrared or radio waves to your headset. Use the digital audio output (coaxial or optical), RCA outputs (red and white) or headphone jack on your TV to connect the transmitter. The connection will depend upon which outputs are available on your TV and/or the transmitter.
Use an RCA-to-headphone adapter. If you don't have a headphone jack on your TV and the transmitter includes only a headphone connection, connect an RCA-to-female headphone connector. This will allow you to plug the wireless transmitter into the female headphone end and then hook the RCA ends into your television's audio outputs. You may also need a 3.5 mm (mini jack)-to-1/4-inch adapter if the headphone plug on the transmitter doesn't match the television jack.
Read more :
Set the transmitter on top of, or next to, the television. For infrared transmitters, you'll need a direct path between the headphones and the transmitter. Placing the transmitter on or near the TV will allow you to take advantage of the clear path you already have.
Plug in the transmitter and turn it on. Charge the headphones if necessary.
Turn on the headphones. Adjust the volume and settings and you're ready to watch TV.

Sharper image indoor/outdoor wireless speakers and transmitter has no audio.

First, determine if the TV device is putting out sound by plugging in a headphone into the audio out of the TV. If audio is there then the
transmitter and wireless speakers system may be at fault.
You can also plug in a CD player playing a disc into the transmitter to see if that source then transmits the audio.

Audio from tv is not restored by turning off power on headphones

It sounds as if you are plugging the base into a standard headphone jack located on the Television set.

RCA Headphone jacks (incl mini) automatically stop the sound output to the main speakers on almost every set I have seen.. or home stereo.. etc etc

In other words you can take a standard RCA jack.. with nothing connected to it.. plug it in while the music or sound is coming out the main speaker.. and it will cut off the output to those speakers..

If you set has audio outputs on the back.. preferably Fixed Audio Out .. you will need to connect your base unit to those.. turn your set volume to 0 and adjust the headset volume using the control on the right ear-cup.

If you have variable audio out.. you will need to go into your TV sets setup menu.. turn off the speaker.. and turn up the set until you achieve a signal and decent volume through the headset.

If you are missing these connections.. your current “work around” is your only solution.

Best of luck

Unable to listen to my wireless

They need a minimum level of signal to switch on the transmitter.
Verify if it works on yet another system.
Make sure you have the right output on your Samsung.
Try to increase the output level of your Samsung...(up the volume, but it may be a fixed output..)

Wireless Headphone not working with my portable DVD player

Firstly, make sure your DVD have built-in IR wireless module so that your headphone can receive the audio signal from your DVD player.

Second, it should be clear which frequency transmitted from your DVD player. Generally speaking, there are two frequency of IR transmitter.One is 2.3MHz/2.8MHz. another is 3.2MHz/3.87MHz. Only emission frequency same as receiver can receive the audio signal.
