One set has a horrible hum. Has anyone else experienced this?

possible interference from transmitter especially if you are using a digital to analog converter try different locations for

No. Both have worked very well. Have you reinstalled the entire thing, including the batteries?

Mine have been great! A horrible hum sounds like a power problem. This unit did not come with a power adapter...

Usually this is indicative of low batteries. I use rechargeable Lithium batteries for long performance before needing to replace. If changing the batteries doesn't solve the problem then look for what you have added into the room that might transmit near or in the same frequency as the headphones. But most likely it is weak batteries. If these are in a vehicle the alternator can cause this noise, but you should have seen this the very first time you tried them out.

Thought of something else. Make sure your power adapter is set to the correct polarity + -, mine is set at +

No, but do get occasional static. I Just adjust the volume up& down, and it clears up. Might give it try. Consider returning, shouldn't do that. Or if not worth the cost, try repositioning the transmitter to a higher position away from other electrical equipment, DVD player, satellite receiver, etc..,

It happens to me when I did not set the audio output to PCM (from the source) in Netflix occurs in some languages. Not sure if we are talking about the same.

I do not have this problem. It could be just a manufacturing error. I would just contact the company about this issue as I do not have this problem with my speakers.

This is not normal. I have the speakers and they do not buzz when there is no sound output.

I have not had that problem, love mine, sorry I was not any help, sounds like a defect or an impedance problem to me.

Thank you! I finally solved the hum problem by plugging the iMic into "Line Out" on my amplifier instead of directly into my turntable. The hum disappeared! Hope you got your hum solved, too. Maria

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?

I found that making sure there was no interference from any other electronics nearby helped. Just experiment with moving the unit, the input cable, and the source of your sound (whatever you're broadcasting) around until you find the sweet spot. I've got virtually no hum now, but occasionally I'll hear some and invariably find that someone has moved one of the elements around. Once I put it back where it belongs, no more hum.

I have heard them make noises as well. If you look at my review 5 out of 8 went bad on me. It may have been just bad luck but I sent mine back.

My first one showed up damaged, it was immediately replaced. My second one worked for 45 minutes, sounded great but then it begin to hum very loud. I just installed it in the trash container hasn't been a problem since, I bought something else.

Yeah it sounds defective. I would suggest calling Amazon to see if you can get an exchange.

You could try looking inside the speakers (specifically the one with the volume knob -- that was where my problem was) and see if the capacitors are the problem. See my previous review of these speakers for more info (http://www.amazon.com/review/R33FG0Y92298KH/ref=cm_cr_rdp_perm)If you had these plugged directly into a wall socket at time of power outage (and power restart) then maybe more stuff is fried. Note... in my case the buzzing sound was not caused by a power outage or from heat, but just from crappy capacitors in the speaker. They have been working like new for almost a year now after the fix. Good luck!

Sorry to be so long, but while the problem seemed to clear up, it suddenly developed the hum again. I have a Technics receiver with a phono output, so I have the turntable set to Phone Off. This worked until today, when it suddenly developed a hum, and when I tried to reconnect the wires the white wire produced a pronounced hum and the red wire produced an explosive pop. I played it this afternoon without incident, and have played it for hundreds of hours since last summer, but today the hum came back with a vengeance.

That's kind of what I had. But it wasn't a steady buzz - more like a loud 60 Hz humm. I even tried to move it as far from the TV as I could. I was thinking there was some sort of interference, and separation might help. But no. Amazon is great about returns. This is first time I had a problem with a purchase.

I don't know, but so far, after a couple months, mine are good. Maybe your set is defective. Try for an exchange.

I had surround sound and two of the 7 speakers hummed when I put the Direct TV HD in "pause." To fix this problem go to the Direct TV remote, setup, settings, audio, and turn "on" dolby digital. Mine was off and caused the hum!

it has a loud hum . I grounded the units directly to the Case of the Computer. It reduced the hum significantly. I replaced both units just last week because these are pretty much junk in my opinion.

They're not noisy for me. Is it the lights themselves, or the power supply you're using?
