My Sennheiser 175 keeps fading in and out all the time. I connected it to my TV’s Optical output. Does anyone have this problem. null

Question

Billy757 · Accepted Answer

Mine did that too. Found out it was my WiFi interfering with the signal. Unplugged my router and it worked fine. I notified Sennheiser and they are aware of the problem.

nevo · Answer

Yes, mine cuts in and out all the time. Like it has a loose connection i cannot find. I am contemplating bringing it back.

Congressman · Answer

Yes. I have always had a problem of the sound, blipping out. Can’t find a reason. Turned unit off/on, turned TV ofF/on. Changed batteries, and recharged the batteries to max. But it still has this random event. The Manufacturer was of no help. Sennheiser just told it was “out of Warranty’ period. This ‘supports’ sucks for a very expensive item. I used to use $20 RF headphones w/ no problems. It makes me question Sennheiser’s reputation.

This is New too: (after 1 1/2 years) now the lights (and power) on the Transmitter seem to ‘fade’ on and off. Unit fails to work when it does this. It is almost spooky. Again, it is totally random. The sound is great, but I can’t rely on any enjoyment from this 175 unit. There will be no support from this self inflated disappointing manufacturer.
My recommendation is; DON’T buy it! 
There are cheaper RF choices. [stay away from Bluetooth to avoid latency issues].

Answer

Yes, I bought these because I thought Sennheiser would make a great product....but they suck beyond belief. DO NOT BUY THESE. Geez I cannot express how much I hate these headphones that I wasted $300 on. This is my last Sennheiser purchase.

Here is the Solution. Wrap the receiver in tin foil and it will block the digital signals around it that are interfering. It works but does not look the best. It is the only solution unless you down grade to the RS120. That one will work with all the wifi signals around the room.

I had this issue crop up while streaming hulu to a chromecast.

I unplugged the wifi router, and also the headphone receiver.

Then disconnected the optical audio input from the back of the headphone reciever made sure the cable's path was clear from the tv to the headphone receiver. It was tangled around some of the other cables. 

I plugged everything back in and once reconnected, the dropout issue went away. Hope this helps.

Definitely a router issue, I moved my headphones and plugged them in to my computer that is located in my basement worked perfectly

I figured out my Sennheiser headphones worked great when my tv was on a wireless signal but the minute I connected the tv to my router via either net cable the headphones cut out, the minute I switched the tv back to wireless the problem stoped. Side note my headphones are connected to the tv bu optical cord. I have the RS 175 model.

When I first got mine, they kept on cutting out, no matter what I did to them.  I tried stretching the battery spring a little, just in case their was a poor battery connection.  The I discovered something.  The batteries seemed to cut in and out, even though they had just came off  the charging unit.  I started trying different batteries.  Some worked better then others, so I questioned why. Nickel cadmium batteries has a memory that has to be reset every so often, especially if they set on a shelf for any length of time.   The memory life shortens when you use them for a short time, then put them back on charge You can’t assume a new set of batteries are new.  To reset a rechargeable nickel cadmium battery, first discharge the battery completely, by leaving the headphones on.  Set them on the charger, making sure they are fully charged.  You might have to perform this task two or three times, before the battery memory starts showing some longevity.  Keep track of the batteries, to see which ones doesn’t charge at all and which ones do.  Throw out the bad ones.  If the headphones work fine for a while, then they start breaking up, it’s time to reset them.  If they are working fine, try to keep from put them on the charger. Remember, frequent charging shortens the memory life.

I own a Sennheiser RS175 and I had this issue. It seems to be a problem with the WiFi router conflicting with the Bluetooth receiver. The router and Sennheiser receiver were the same level off the floor, could "see" each other, and were about 5 feet apart from each other. Sounds weird I know, I was skeptical. I put the Sennheiser receiver on the floor so that the entertainment center is now between the two. I haven't had a problem since I made that change.

Before I got a longer optical cable to run in the wall and into credenza below my tv mounted on the wall, I never had this issue. When I ran a higher quality Optical cable, in the wall, next to my HDMI cable to my stereo receiver, bam the issue started.

I first thought it was because the headphone receiver was behind a glass door but quickly determined that was not the case.

Put the unit back on top of the credenza using the new optical and plugging directly into the optical of the tv and problem was gone.

Going to try to channel a new path, behind the wall with no interference and wrap the optical wire. Guessing there is a better solution besides tin foil, like the metal tape you have on your furnace.

Other than that issue, the unit is flawless connection.

Answer

Yes,erratic audio on new wireless phone..

Seth · Answer

I had this issue.  I have found turning off the WIFI mode B off on my router.  Mode was set to G/N/AX  frequency was set to 20MHz,  and then swapped it to a manual channel.

Liam · Answer

I set the receiver away from the tv on the floor and it helped.  Tin foil suggestion seems to help as well

Casey · Answer

We had a storm and I lost power for 5 hours. When the power came back on my headphones started working properly again, so maybe if you unplug them for several hours you may correct the problem.

Unplugged the room wifi repeater and the audio returned to normal.

I barely bought these headphones a month ago and I only have this problem when I'm watching baseball, SF Giants games. It's irritating that I can't catch everything the commentators are saying.

Josie · Answer

I have two pairs of the 175 headphones in two different locations, both are connected through the TV Optical output and i do not have a fading issue. Even when I go into the other rooms they work normally.
