These Wireless Headphones are my very first purchase on Back Market and I've got to say I'm very impressed with what I got. First of all, these are $70 headphones brand new but I was able to get them refurbished here for only $4 in Excellent condition! Not only that I also got a free 1-year warranty! The headphones were packaged well with bubble wrap and are in great shape. As for the headphones. They are awesome since they have tight integration with the Apple Ecosystem. They support features like Find My, Siri, Audio Sharing, iCloud Device Switching, and more. They also work great on Andriod with the Beats App on the Play Store but will of course work on any other device that works with Bluetooth audio like Windows or Nintendo Switch. The audio that comes out of these headphones is clear even in higher volumes and the built-in microphone is also pretty good too. Overall these headphones are great and I will be buying from Back Market again
