This was my first pair of wireless ear buds. I have more experience with in-ear wired headphones and higher end home theater AVR/speakers.These were advertised as being useful for working out. I found they were easy to insert into the ears and locked in nicely. They are so comfortable I would forget I had them in. You take them out of the case and they immediately turn on and find the bluetooth connection, in my case an Iphone X. They tell you when they are connected. At that point you can use the built-in mic to issues commands to Siri or talk on the phone.They came with a wireless charging case using a USB C cable. While in the case they are not likely to get lost and the case keeps track using % numbers. The case charges up quickly and battery life was good. To charge the ear buds they simply have to be stored in the case, charging is automatic.The sound quality is what I like. Clear voice and vocals, bass was full and not boomy.These are well worth checking out.
