Bought these on Amazon for $49 and have used for a week. These are amazing for the price! Pairing with both Android phone and Windows Surface Pro tablet is easy. Bluetooth connection with both devices is automatic and has been reliable.
Sound quality is what blows me away. I own a pair of Apple’s AirPods and these sound BETTER at one-third the price. Also, they fit my ears better and have the benefit of blocking out surrounding noise.
