I have one that works ok, except that there is a loud buzzing sound in my headphones when I use it. Is that normal? How do I prevent it?

Seems like it might be a flaky ground connection. If you've tried other headphones, and if you don't get a buzz when you plug your guitar into another amp, I'd guess that the AmPlug has a faulty ground connection inside, most likely at the 1/4" phone plug.

First time I plugged in headphones, I didn't plug them in tight enough to the socket, so i also had bad audio with buzzing. The microphone connection was apparently shorting one of the earphone channels. Sounded terrible but securely plugging solved it.

My headphones do the same thing. I believe it is charging. I have used them without issues.

I have had the same issue w/ some Bose 20i headphones. The male it won't fit completely in the female end. I'm not sure if it's defective or it's just too small.

I think the head phones are defective. I sent mine back because they didn't work on my phone, iPad, and other devices.

It hasn't mine. I have the sennheiser 360 gaming headphones. So far I haven't experienced anything like that. May depend on the make and model.

Hi, sorry can't help as I don't have experience with this devices. Anyway you ordered outstanding headphones, top class for sure, I used with a good DAC and a Magny amplifier and really are one of my prefered headphones (well, I keep the 250ohm version as I almost never use portable devices for music). Hope you likes the Beyers. Leo.

Yah you might have a faulty pair. Mines work just fine with the noise cancelling activated.

No, you are not doing something wrong, I have the same problem, sometimes all I get out of mine is buzzing, not only can't they hear I also can't.If it's not too late send them back.

I'd like to know the same. It happened to me exactly you described and my headphone only plays on one side and it's very disturbing to have to fixed it every other stroke. If you find that out let me know. Tks Claudia

No, it's not normal... Make sure that everything is plugged in correctly(power cord, aux cable, etc.). And make sure that you earphones and your music device are capable and functioning. If nothing works, contact Nuforce and tell them that you got a defective product and they will help you out.

Yeah, that happens with these and every wired earbud. Try looking for some Bluetooth headsets if it bothers you that much.

No, the buzzing sound is always on, unless you are on mute. I had mine for a couple of months now and it seems to have gotten worse

I discovered similar issues with my recently purchased HA400. It was the headphones!!! Not every headphone, but the type with microphone built in, designed for use with phones. It seems that some (all?) adapters do not correctly place their internal contacts for the special plug that comes with these headphones. Instead, the signal is shorted out and makes it appear that the amp is broken. Happened to me until I figured it out.

Hmmm . . . the only thing I can think of then is that perhaps you have a defective unit. On mine, the low end is full and powerful, so much so that I've never felt the need for a sub (I'm using JBL L880's by the way). Curious--do you also notice this phenomenon with headphones?

That is what I have & it works great. I use it a lot. Can't plug in headphone while using it, but I just take it out to plug in headphone.

Hello Dale, don't forget about the volume control on the back of the unit. Also, switching the polarity might help on the buzzing sound. Hope this helps.
