does anyone else hear a high pitched hum in the system once you start playing sound from your device through bluetooth?

No, sound quality is still excellent. Try moving it to another location just in case you are picking up interference from something else nearby.

I don't really pay attention to that really mostly on the music when it plays

You have to go into your phone settings. System&gt;Accessory&gt;Dock Sound needs to be checked.

Nope, more likely than not the buzzing is coming from your output source. Try playing audio from a different source and see what happens.

Could be cable / power point issue..the XLR cable will cut off the hum..( Balanced cable )..

No. Are you using the 3.5mm jack? This can sometimes cause a buzzing sound if not inserted all the way. Or if the phone is charging with the 3.5mm jack also plugged in.

While playing music is as good as the Bose can do (at least for my standard); once the music is over and the system still powered on I can hear an unpleasant "electric" noise. I must say I'm switching off the system now when not in use to avoid that noise

You know I had to go and check! However, I have an 828LM and no hum whatsoever. Have you unplugged (the replugged) the unit and tested it away from other equipment for this humming noise?

The hum might be due to a ground loop. This problem often happens when you interconnect devices via RF/audio/video/etc. cable that are plugged into electrical circuits with different grounds. To troubleshoot this, try disconnecting FM antenna, input and/or output cables from your receiver. Assuming that you have any kind of cable connecting the TV to the receiver, also try removing the RF cable from the TV. Cable TV hookups are reputed to be common causes for ground loops. If the hum goes away with a particular cable removed, search online for a ground loop eliminator device for that type of connection. An inexpensive audio ground loop eliminator is available at RadioShack stores; higher-end audio ground loop eliminators are available online. Cable TV ground loop eliminators are available from online sources. For further information, search the Web for the words "ground loop". Hope this helps! Dave

I had a similar experience. The bluetooth connection worked fine for the first couple of weeks. But then during playback it would suddenly begin producing something that sounded like feedback. The unit also began losing the bluetooth connection. I shipped the unit back to Nuforce (which cost me $30) and they replaced it. But the replacement unit has also produced the feedback sound a couple of times and sometimes loses the bluetooth connection. Nuforce needs to do better.

The answer is yes, I just got it hooked up a few days ago and I'm still figuring out how I want to configure my system... with that said, the other night I'm watching a dvd. Them hum was coming through the system. I turned off the Bluetooth on my s4 and that seemed to help. It seems to me it's constantly searching for a signal. Now, I've not read the Bluetooth section of my docs yet, but I'm hoping there's a way to disable it while doing other things like tv, est.

not sure exactly, but have you tried using a different cable and/or mic to see if the hum goes away? perhaps one of them is faulty.

Yes there is a hum (slight). What I hear is constant; no matter what volume I am set at. I actually had to exchange my first set due to amplifier 'popping'. Again, volume setting did not matter. I have decided not to let this hum problem bother me because it is inaudible when something is playing.

I have had this be an issue with some of my streaming music services. The issue apparently was with them as they released patches to fix that. I would connect it with the cord and see if you have the same issues. It might just be interference of the Bluetooth signal etc.

Have you ruled out a ground loop as the source of hum? http://www.youtube.com/watch?v=4YM1iwC6vhg http://en.wikipedia.org/wiki/Ground_loop_%28electricity%29

My iphone 5 plays through the Bluetooth but has a whine that I need to figure out why.

Is the hum coming from the power adapter itself? If so, it might be getting ready to go bad. Replace before you have a fire. If the hum is from the speakers, re-post and I might have some suggestions for that as well.

It is a low pitch hum. Usually mine is on low and I get used to it and don't really notice it. Higher speed is more noticeable, but still more a medium pitch, not high-pitched.
