    • Absolutely Love These Headphones!
Review Image by Iris
I love the Monster Open Ear AC210 wireless headphones in rose gold. They look beautiful and feel very comfortable, even when worn for long periods. The open ear design lets me enjoy music while staying aware of my surroundings. Sound quality is clear, Bluetooth connects quickly, and the battery lasts all day. Great quality, stylish, and practical. Highly recommend. ... show more

    • SO COMFORTABLE!
Great sound, and very comfortable! I totally forgot i was wearing them. They are so light! Most over-the-ear headphones kill my ears after a very short time. They stay put as well, through playing at the park with my kids, riding bikes and cleaning house. I will say I wish the battery life was longer. They go dead before my ears have had enough of wearing them. 😁 I'll be buying another pair. ... show more

    • Don’t buy. It’s cute at first later you will need to replace it
Review Image by Jennie
Battery doesn’t last. First time I used them they were loud after 2nd charge somehow the sound quality is low. I bought this for work and contarle pushing carts so with the sound of carts and people talking I can hardly hear. I stayed hang my AirPods or other brand earbuds I have. They are cute tho but cute isn’t enough. I don’t recommend. It’s been a month and I can’t get a refund since the return window closed. ... show more

    • Easy to use. Love the comfort and sound quality.
Review Image by Tre-ski
Sound is wonder and the price was great! Very comfortable I forgot I had them on. The quality is better than I expected and loved the color. Take both the right and left pair out to pair them together at one time.

    • Sound quality is so-so.
These are ok. I paid $20 for them so didn't have high expectations. They are very comfortable. Battery life seems adequate. The button seems to only turn music up. Call quality was fine. I'm used to airpods that go in your ear, and I've noticed that the sound quality of the airpods is far superior to these monster ear phones. The Monster ones are great, I'll use them at work, but if I want to jam out, I'm going to pick the airpods over these. ... show more

    • Nice! Just need some improvements
Comfort, sound quality, and phone calls are all excellent and 5 stars. But… the case and battery life are the issues. The case has no display to show charge. The lights are red or white only so only way to see if they are charged is on my iPhone. The magnetic seat they sit in is very shallow so barely holds them, sometimes leaving them loose in case and still connected to phone after putting them away. I wear one at a time and only lasts 3-4 hours then I have to switch. Also I would prefer to only tap ONCE for pause/play/answer call and more of a pink color would be nice However I am still keeping since they are so comfortable and sound great! ... show more

Great sound and they stay in my ears!

    • Really cute, pretty good sound - but charge simply does not last (Bong-bong! Bong-bong!)
Probably the cutest earbuds I've owned. Beautiful. But think fashion, not tech. These charged and connected easily; no speech needed. Sound was crisp and seriously pretty good. After way fewer hours than advertised, both began bonging and complaining of low power. No problem; fully recharged and carried on next day. After three hours, left one started complaining. Well, three hours doen't work for me. ... ... show more
