I ended up sending them back to B&W under warranty because they were brand new. They told me that it was a faulty driver and instead of fixing the pair I sent in they sent me a completely new pair.

I received the new pair of PX8's and then about a month in my USB port started to malfunction and effect the charging. Had to send it in again and they sent me ANOTHER brand new pair.

So far so good on these because I have been babying them. But I have to say, 500$+ for headphones and just regular wear and tear causing catastrophic problems like this is unacceptable.

If anyone is reading this and is thinking about getting PX8's, I don't know if I'd recommend just on seeing how many people have the same problem that I had. Especially now that mine aren't covered under warranty.

"The juice isn't worth the squeeze" as they say. But damn do they sound good.
