These are open-ear Bluetooth earphones that don't block your ears. They hook over your ears and are lightweight, so they won't hurt even after long periods of use. The microphone function is also excellent, making them perfect for online meetings during telework. I've used them for about six months, and I've had no problems with sound quality, microphone, or charging during normal use.
