I have the same thing here. It's normal for most powered speakers with an external power brick to have some audible sound when the transformer cuts to standby.

Yes - we just got ours and we have noticed the exact same thing. We are contacting Bose.

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!

I've had success pulling the power plug, counting to ten, and re-plugging. That it loses functionality seemingly at random and within a few weeks of purchase doesn't say much for the player. Has anyone else noticed how loud it is? That seems impossible to fix, a permanent annoyance.

I had this happen to me whenever the speakers were on, charging, and the headphone jack plugged in to the computer. If it is off and only charging, there is no noise emitted at all.

No, never. We are very pleased with this transformer. It runs noise free. What I can tell you though is that the one we had before this one got fried, as someone hooked an appliance up to it that was exceeding the allowed maximum wattage. That one did make a loud humming noise before it blew. If you are certain that your wattage is a match, it might be defective. The only other thing I can think of is try setting it on the floor, that is where I keep mine. Somethimes transformers can make surfaces vibrate and cause a humming sound while running.

I got the same issue (connected with USB) plus, has static. The on/off control is in the weird location and many times I get the Static with a noise in the speaker. They even get sound when I turn on and off the light in the room. It never happened with the previous speakers.

A hum that you can hear is normal. If it is loud, something is wrong. If it is noisy without a load connected, I would replace it. Are you sure you have not overloaded it?
1664945
Yeah, that sucks. I figured it out after I couldn't return them anymore. I just gave them away and bought a much more expensive one to replace them. I got a Crown 28M to replace my two Pyles. It has been on for about 4 months now, and never hummed. I needed an always on system for PA work.

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.

I noticed it too. When the device is connected via the instrument connection the floating ground will cancel any noise. One must remember, this isn't a professional piece of equipment with layers and layers of MOSFETS, JFETS AND TRANSISTORS To switch on and of the signal. So, even though there is no signal, it's amplifying the hum from the AC transformer as well. In common terms, it needs to be connected to a device to cancel the noise. Even in the ground, or lift phase.

Is it a ground hum? Because if the speaker has a hum, there is nothing wrong with the speaker itself.
1841224
Yes same thing happened to me. I ended up returning my unit. I went to the audio store to see if it happened to other units and it did. I would turn up the volume and the sound would cut out and not come back on unless I power cycled my head unit.

Are you sure it isn't the subwoofer? It stays on all the time even when the system is turned off and produces a low level hum, constantly. That seems to be the norm for all the subs and the Onkyo receivers. I was surprised to walk into my media room and hear the hum coming from the sub and the system was turned off. Sub is always in stand by. Just a thought.

mine doesn't hum. I wish I could help. Maybe it is the model. I had one, that i loved, and one day, it just quit working. They didn't make that model anymore, and I had to cut the plug, and send it to them, and then they sent me the most similiar model. But I really loved my old one. It was beautiful. This one works great, but is not as aesthetically pleasing to the eye. :-(

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.

As one of the other answers suggested, I also tried using a 12v power supply. This significantly reduced the ground noise. It's a shame that this product ships with a 15v power supply that seems to be the cause of the ground noise. Actually, the device says "9-15 VDC" so maybe it's possible to use a power supply that's even lower than 12v. I'm not sure. But still there's some ground noise left even though I'm using 12v. Not nearly as bad as with the 15v, but not entirely gone either. Good enough though. Hope this helps in any way.

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