My daughter bought this product for me. I always wear a ear piece with wires. She said she was tired of me rushing to unwind the wires whenever I need to use the ear piece. I love that I don't have to deal with wires. When I use this truly wire-free I can hear the person on the other end clearly. I love that it stays in my ear and doesn't fall out. The range is good if I go away from my phone, I don't go a long way but I can still talk. The only thing that I have a problem with is when I make a mistake and touch my ear piece I hang up on my party. I also love the recharging time. I love the talk time before I have to recharge.
The earbuds have a surprisingly decent battery life. However, when putting them in the charging port they're left charging or would turn on automatically which drains it. That and it has trouble connecting to the device if you're more than a foot away from it.
Best fitting over ear earbuds I have ever owned..and I've had a lot. They don't fallout during lifting or running sessions at all. There are a few kinks though. The right ear bud doesn't sit right in the case for charging and has to be manipulated manually with the case open. This also causes it to be in pairing mode and connect when u wouldn't want it to (while u are driving and they are in the case in your gym bag for example). Also, there are a lot of pairing breaks when you are moving, especially in a crowded gym...it's cuts in and out maybe do to other Bluetooth interference. If you are stationary it's fine.
