Bluetooth 5.0 with Great Sound Quality 1. Bluetooth 5.0 technology with a more solid connection and an effective wider range (80ft) than Bluetooth 4.2. No longer worry about losing connection when you take your phone out of your pocket. 2. Hands-Free calling and voice prompts. You won't miss a call when working in a noisy environment. 3. Stream Entertainment - Enjoy clear music with great sound quality. 4. Comfortable for wearer. I use these headphones in my business as a Landscaper, very comfortable, great volume, and can clearly hear my music over the sound of a ride on lawnmower. Outside noise cut down greatly (25db). Highly recommended. I've used very expensive versions that are limited in volume by EU directives, you can't hear what you want to listen too, but with these you can.
