Question about Sennheiser RS 140 Consumer Headphones

1 Answer

Hissing and poor sound quality

I recently bought the Sennheiser RS140. I have plugged them into my TV and get fine sound quality but in all honesty not knock anything too dynamic.

Second and main problem is that there is a continual slight hiss and in moments of silence or quiet there is a real bad hissing.

I have reset, re-tuned, fully charged, moved the transmitter around the room, tried increasing tv volume and vice versa.

Is this a common fact with all wireless headphones or a specific error?

Thanks for help

Re: Hissing and poor sound quality

Well it could be interference from the TV, computer, or other 900Mhz device (some wireless routers run on this frequency).

I'm currently dealing with the same issue myself, if I find a solution I'll post back.

How do I get the tv sound on after plugging speakers into audio on my TV?

That's what's 'sposed to happen. You get TV sound OR sound through headphones - not both

No audio just static

Surely the instructions for your new Samsung TV provide at least minimal information regarding what does what.

The right headphone on my sennheiser eh 150 doesn't work, Iv'e opened up the headphone and both the cables are securely held in place so its not the speaker, the cable is also fine no sign of any damage,...

I have the same problem, but in my case, I pulled accidentally the cable when it was plugged, but I can't neither see any damage in the cable,plug or headphone; in fact, it looks very strong. I did the same, opened the headphone, but everything's in its place. I've been browsing for two days and can't find any article related to this problem. It would be a shame to have to get rid of these headphones, they sound great!

Brand new Sennheiser RS140 headphones stopped working

Mine is a bit older (2yrs), but I have exactly the same problem. Absolutely no sound from the headphones (no beeps). I also tried new batteries, but still nothing.

If you have a solution, let me know!

RS120 Can still hear TV when headphones are on

Ok.. first.. the simple thing is to go into your television menu and turn the television speaker OFF.
Then exit the menu and turn the volume up.. try your headphones now.

Next.. check the back of the TV for a FIXED AUDIO OUT.. plut your headphones into these outputs.. if you have these.. you can simply turn the set down.. and use the volume control on the headphones.

Fixed broken headphones but sound quality has plummeted

 it sounds as if the wires are wired wrong . yes it is best to solder the wires.all jacks are the same,yours will be stereo i believe. is the braid attached to the earth point, the two other wires attach to the centre of the plug and the other terminal point. these are right and left.

No sound, only static

Hi I had the same problem and just emailed Sennheiser.Go to the menu on your TV and change the variable audio output to fixed. I use the headphones through the home theatre so the volume must be max on the home theatre and then you can adjust your headphone volume. It absolutely worked and I don't get anywhere near the static noise when I go to another room with the headphones on that I got previously. Also be sure your audio cable is plugged into the fixed audio output socket. I did not have to do anything with that.
