Annoying high-pitched buzz/hum (~1 kHz) from R speaker when charging: is it really only when they're near full charge?

I'd love to help but I haven't noticed this issue...admittedly I am not a serious audiophile..........

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.

I have had no trouble with my speakers. They are great for such little things. I personally would return them to Amazon.

I have not experienced any problem as described with my speakers. Sorry I can't be of more help.

If I charge it at the same time, it will have the buzzing sound. Otherwise, it is perfect and sound great.

Sorry mine don't buzz. But buzzing normally occurs if the speakers are being overdriven by the varying voltage levels that produce the sounds. The speakers have a wattage rating that is optimum that is a design in factor. You could be providing to much power. But try disconnecting one speaker after the other. That way you can tell if you have a bad individual speaker in the pair. If there is no change indicated the problem lies somewhere other than the speakers. Ensure that the system is grounded. If not grounded you may be hearing a 60 cycle buzz induced by normal AC power.

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?

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.

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.

All of what has already been said, AND, the headphone link is very noisy. Mine is anyway. Buzzes...hums... Same with two different inputs, two different power sources, no matter where it is placed. It's not an enviromentally induced noise...it's the converter.

Mine does not make a buzzing noise. Contact customer service they will get you a replacement charger out promptly. Mine do take a full charge and last as long as the OR battery.

They have active noise cancellation that requires recharging. I suggest that there is some other sort of signal processing happening also. The charge seems to last well if you remember to unplug the cable from the headset.

The unit needs charged. It will continue until charged. Did it come with a little red plug that you put into the alert or alarm spot on the front? If you have this, putting the plug back in should stop the charger from the high pitched noise. Let me know if this works for you.

The charger i received does not make any noises, so hopefully it helps you identify the issue. In your case i would definitely try to get a replacement as this noise usually corrseponds to malfunction. To add...my last charger which i replaced made those noises and aoon after stopped charging.

I don't think I've heard any on mine. If you are hearing the hum while using the RCA jacks then maybe trying unplugging it from USB/have the turntable and speakers on separate outlets. If you are hearing it over USB then maybe just try the same isolation but between the computer and the turntable.

OK!........4 or All of mine are making sequel and crackling sounds when a phone call comes in. I was told to unplug the charger and let it set for 15 minutes and then plug them back in. They are still making large crackling sounds and squeals! Now what should I do because I purchase the 6 set through amazon. The one out in the shop I doubt is a problem so I'm not worried about #6! Up until last week everything was great. Now I'm having problems and I put in new rechargeable batteries but I still get the screeching and scratching noises! Bruce HartogWildwood, FL 34785

This is true. I've learned that if I open the cover over the charging site when I use it the sound is fine. Or you can use the speaker which works fine. Hope this helps.

Mine did the same thing. I only kept this a week due to the poor sound quality. However, the problem seemed to go away after charging the unit a few times.

I did noticed that. I also learned it was due to an inadequate power supply. At higher volume levels I found the best performance at 13.5vdc. I accidently discovered this by taking the speakers to the beach and using a car battery to power them. As the voltage dropped after a few hours of use, that's when I noticed higher pitched volcals being drowned out by the lower signals.
