Monster Open Free AC100 Open Ear Headphones, Bluetooth 5.3 Wireless Headphones with Earhooks, Immersive Stereo Sound by Dual Large Driver, Clear Talk, 30H Playtime,Waterproof Sport Earbuds for Running

Review: Best ones I have had yet - good fit, comfortable, good audio - Very pleased with the quality of sound, the fit of the ear buds, quality materials, holds a charge, so far I have not had to recharge after a few hours already of use, good connection. I need something that does not go in the ear and this proved to be ideal. Not heavy and sits comfortably over the ear. The ear piece itself does rest over the ear opening but does NOT go in the ear. The instruction pamphlet lack clarity and you will find out more by just experimenting with the device. I get on my voice mail to test everything out, it beats irritating friends and family - LOL. If you wear glasses it works best to put the ear piece on and then put on your glasses.
Review: Really good earbuds - I used this open-ear earbuds for a week and like it. The build quality is solid and the sound is clear. What I like most is they don’t block my ears. When I’m working in the office, I can still hear my coworkers important conversations. They’re also great for workouts or driving, since completely blocking ears might be unsafe. I could enjoy music while still awaring of things around me. They fit my needs very well. I recommend it and worth to get it.
