Q: Bought this to replace old wireless headphones. I was looking for something cordless and had good reviews. At first it worked as expected but after a week of use the left ear bud stopped working. Don't waste your money. I'm sure these have great sound quality if you are comfortable with buying poor quality. Will not purchase from this manufacturer or vendor again based on my experience. Do yourself a favor stay away.
A:
Bad review
