Review on COOSII Bluetooth Headphones Wireless with Dual Microphone - V5.0 USB Adapter for PC, Laptop, Chromebook, Cellphone - Over Ear Headsets for Home Office, Online Class, Skype, Zoom, Call Center - 40H Battery Life by Doug Twilights

Very nice headphones. In general, the sound quality is very good. While my laptop supports BT capabilities natively, the included BT dongle adds additional value. Since the BT dongle is paired with the headset first, it connects within 2-3 seconds and you don't have to go through the BT pairing process of Windows 10. Just works every time. If you leave the 30ft range (which is actually closer to 20-25ft), the headset will announce a shutdown. When you return within range, you will hear the headset connect message without user intervention. I listen to music when I work (not in meetings!) and the sound quality is great. The only reason I didn't give this one a perfect score was for two reasons. 1. It is not possible to have a hardware mute button that works in Windows 10 communication programs. The mute button works when paired with a mobile phone, but hardware mute adds additional benefits to the device2. the overall volume is somewhat inconspicuous. With the volume set to 100% it sounds good (no tearing or hiss/distortion) but you want a little more volume. My other wireless headphones have enough volume and I wish this device had added a bit more.
