Hello gents,

Figured I'd ask for help around here since you guys have been around the block before. I very recently bought new edifier s350db speakers for computer, and there is a high pitch squeal coming from them whenever i have them connected to an audio source. It's sort of subtle enough to be drowned out when playing or watching something, but it's still there and it's damn annoying.

I have two connections that I've tried, I used an optical connection to my PC and it squeals while connected to it, once I unplug the cable from my computer it stops however. I also tried bluetooth with my phone and I was surprised that the squealing happened there too.

Any ideas/advice?
Maybe it really is all cocks in the end.

That sounds like a hardware defect! With the optical and bluetooth connections, it can't be current parasites from the audio source.

Even high end gear (which your powered speakers isn't) can have such problems: I remember buying a Rotel preamp whose left channel sound was louder than the right, despite balance being set at neutral: the preamp was replaced and the problem was gone.

I thought it could be that, didn't want it to be cause these are so new :( I sent Edifier an email about it so hopefully they'll get back to me.

It does sound like the speakers are defective. I have encountered this once, a long time ago. I brought the speakers to the company that made them and interestingly an audio engineer there could not hear the sound that I could easily reproduce with a particular recording. Ultimately I left there with a replacement pair of speakers that did not have this defect.

If they are still under warranty I would just ask for refund or replacement.
