Well I received this product Monday, it's friday and won't turn on anymore. It was wonderful for 4 days, but like I didn't spend 30-40 bucks on this for it to stop working. I'd like my money back, considering my old heating pad lasted 3 years.

Definitely not worth the money. They overheat and burn my ears very quickly after being turned on, the battery life isn't more than 30 minutes, when trying to watch a show or video the audio is very behind and they have this constant beeping/buzzing noise while they're on that you can still hear over your music.

It's just waste of money. I would return it. Just using it for desktop for recording monitor. The sound is too low. And base is soo poor. Don't buy it.
