3.4/5These headphones would work for two days and then stop working for two days. When they weren't working, it was impossible to connect them to any devices. The product had a lot of issues, including getting stuck in pairing mode and being impossible to reset, which was incredibly frustrating. I bought them in "Good" condition but am returning them for an "Excellent" condition pair to see if that makes a difference. Based on my experience, I advise staying away from the "Good" condition option.

4.6/5Sound quality and noise cancelling far exceeded my expectations at this price point. They barely fit over my ears which is okay, at least they aren't crushing my ears. The microphone works decently. Battery life on them is great, I can get around 20 hours from them at my normal volume levels. However, the reporting of battery % is awful. It stays at 100% for what seems like hours then drops down to 60%. It originally would say, "low battery please charge" when it got low enough, now I just get "Power off" and they just poof. So instead of charging them when needed I am plugging them in every night so they don't die with no notice, last nights power off was reported at 60% since I had just checked the battery before they died, 10% when powered back on.

3.4/5We love back market but not happy with this product. When using the wireless feature the left side has no volume..in researching the product it seems to be an issue. As an adult I would return this and get a refund but it was a gift for a teenager and the teenager is willing to use the cord and hope for the best.
