Subtle, Cool, but the BUZZING sounds?

Makes a subtle yet significant difference in my tone, however there are times when it makes some rough sounding feedback and noise interference that i cannot seem to figure out. Whenever I use the 9V power input it make a terrible sounding hum so I can only use it with the battery. Looks super cool though,

It works but when plugged in with a microphone there's a buzzing.

I like the color, the size.  I actually LOVE the color and size, but :-(  When I talk to people they hear a loud buzzing noise.  I can hear them crystal clear, but all htey hear is buzzing!  Also, I am unable to download my email.  This is a disappointment because I can not afford another right now and it doesnt come with a warranty,

I chose this soundbar setup due to its relative simplicity and compact size, as well as the low price.  Until fairly recently, it performed adequately, and as the other reviewer noted, the richness and depth of sound it provides is far better than any built-in television speakers.  However, from day one I felt it produced too much background noise - not a big deal at high volumes (just a steady static/hissing noise), but more than a little annoying at lower volumes.  For the past two weeks or so, the hissing became more of a buzzing, and is steadily worsening.  Initially I thought it was the optical inputs, so I switched to AUX and the noise is equally bad.  The buzzing seems to originate in the subwoofer, and is passed along to the soundbar through the 8 pin cable.  In any case, it has gotten to the point that the excess noise outweighs any benefit the system originally provided.  I should also note that it bears an appearance of something cheap and old-fashioned compared to most modern A/V components.

Hey I pick up the Pro thinking it would be better the video is great but then again the background buzz noise is bad I went on there web site and this is what I found...
Problem: There seems to be a lot of sound interference (buzzing) on my recordings, even in a quiet room. Why is this?
Resolution: The level of noise that you are experiencing with the camera is normal. Due to the sound activation function on the Muvi Pro the microphone is extremely sensitive therefore it will always pick up noise even in a quiet room.

Well they should fix it again pretty bad background noise..

While sturdy and seems to be well-made, it has one major flaw -- buzzing. Specifically, on a Nokia QI charging plate, while on a night-stand, it would have this pulsating buzz that is audible from 10 meters away. My previous wireless charging case was completely silent, in that sense I attribute buzzing as not normal. I have not returned the product, will probably use it in-car where buzzing can be ignored.

The sound quality is really pretty good. It's got pretty good bass, mid, and high. There's ok bass, and it doesn't get boomy. But there's an annoying buzz that kills my enjoyment from using them. The buzz is a constant quiet buzz that can be drowned out with louder music, but the fact that I know the sound will be back at a quiet spot ruins the headphones for me.

This is made worse by the fact that I use them at night so I don't bug my wife with ipad sounds. I tend to play games with the music off and the sound effects on. Contstant buzzing! I was really excited to lose the wires with these, but I went right back to wired headphones.

So if you listen to only busy music, and don't listen at very quite levels, you might like these. But if you listen to sounds, audiobooks, or at quiet volume levels--these will drive you crazy!

It's just too bad because again the sound was pretty good other than the buzzing. I'm going to try them while exercising and I think they'll be good enough for some situations, but I'll not be using them for the before bed usage I wanted them for!

The unit itself seems nice, however I get a buzz on every speaker I've hooked it up to so far.  I feel like it's the power transformer, but it could be the unit itself.  I've tried ground lifts, a hum eliminator, with no avail.  Ended up using my old normal 2RU amp.

I'm using this to go from a new blu-ray with digital audio to a sound bar with RCA inputs. Sound quality is good but there is a buzzing when the sound is turned off. It's not loud or annoying but its there. I.m still using it :)

When using the headset, there was a constant buzz when the laptop was plugged into the power outlet.  If I unplug the laptop, the buzz went away.

They make a weird humming noise. I don't know what that's about kind of annoying.

I ordered two of these to be used as 12V LED power supplies.  They arrived quickly, which was great.  But both of them make a high pitch buzzing sound constantly when in use.  I am only drawing 2A with the LEDs hooked up to it, so I know I am not overpowering them.  The high pitch noise drives me crazy!

There is a buzz on the line when I plug it in,  but for the price I can work with it.  Using a 60hz filter application seems to have reduced the sound a lot.

They have an annoying buzzing when nothing is playing. I think they were messed up by previous owner. Bose items are normally not an issue.

1. It makes a buzzy sound. It is a quiet buzzing sound, but it died buzz. Incandescents don't buzz. I noticed this because I installed one in a lighting unit in my bedroom that has two other incandescent bulbs. As I was walking around I kept hearing this annoying buzzing noise that I finally traced to the new LED. So annoying.

2. It doesn't dim as well as an incandescent. The aforementioned lighting unit is on a dimmer. The incandescents dim down to the point that they cast a romantic glow on par with candlelight. The LED? Not dim enough by half. I would say the incandescents dim down by 90% and the LED by 30%.

This was my first experience with an LED. I'm returning it tomorrow and stocking up on incandescents while I still can. Hopefully I can buy enough incandescents to tide me over until the problem with the LEDs is fixed.

The headfones have great clear sound when watching movies, very comfortable BUT......... you can hear buzzing during silent sections. Its not loud but it is detectable anda distraction when watching movies and shows. Some people are not bothered by it but once I detected it, it bothered me constantly.

I have this buzzing sound coming from the DVD player that makes the experience of watching DVDs horrible.
I don't know how to eliminate the buzzing sound. Another friend of mine bought the same DVD player but used HDMI cable to connect to his HD tv. He did not have this problem.
I, on the other hand, still don't have an HD TV so I have the buzzing noise going on on my installation.

Can anyone please help me to eliminate this noise?

Thanks.

Update on 1/5/12: I figured out what the problem was... I had plugged the red cable in the wrong place in the dvd player... the red one is an AUDIO cable and after I plugged it in the right slot it worked perfectly...  GREAT SOUND...  this dvd player is really great!

Thanks.
