This looks like an OEM unit offered by multiple vendors. However, no complaints. At the time of purchase I bought it for $16.99. I've bought more BT headphones than I can count. In terms of sound, it offers excellent value for money, outperforming other BT devices with higher specs and features. Classic question: Does that sound good? Yes. Does it work well for voice calls? I've given up trying this for calls with cheaper devices another customer might think. No problem with the price.
