Solid open-ear option and looks good
I have been trying several different brands of open-ear and bone-conduction headphones, hoping to have a few pairs stashed around my house and in my purse for use with my phone and laptop. I will admit the aesthetic of this with the off-white and gold really appealed to me, which is one of the reasons why I bought them. I also liked that they were well under $100; if I'm going to have several pairs of headphones I need them to be high-quality and on the less expensive side. First impression, I was not certain that these would fit but they are flexible and curved around my (smaller than average) ear. The sound is actually quite loud in comparison to the two other pairs I have. I have not used them for phone calls yet, but for music and podcasts these are perfect. It was very easy to connect to my Android phone, and it charged in less than an hour. I have not used them for more than a couple of hours without charging, so I can't speak to the longevity; I don't necessarily need them for those since I always have my external battery and my USB-C cable with me wherever I go. All in all, very happy with my purchase considering my primary considerations are value/price and ease of use/portability.

Great Headphones!
Was looking for some open ear style headphones and came across these. They were on sale so I figured I’d try them. I now use these headphones more than my Apple AirPod Pros!! The music is so clear, they’re comfortable and light on my ears & the battery life is great. Like I said, I got them when they were on sale for $20 but after using them now for almost a year I’d honestly buy them at full price if I had to buy them again!!!

Pretty good
I am happy for the most part. These open ear buds are light weight and fit well (little bit loose) they are comfortable and have a decent range of connectivity. The sound clarity is good enough for my needs however I’m not using them with my phone so I can’t speak for the sound quality on a call. They hold a charge for a long time and also will charge in the case so really get a lot of use on a single charge. I got the pink/gold ones, very posh and girly. I recommend them for basic stuff, they might not be right for everyone so think about what you need and also the price was absolutely reasonable for them.

Comfortable design
My boyfriend ear hole is relatively large, and the in-ear type is not tight enough, and it is easy to lose. The design of this plug-in is very good, comfortable to wear, and the call is also very clear.

My absolute favorite over ear earphones!
These wireless earphones are my absolute favorite. So much in fact, that I ordered a second pair for back up! I have an ear condition where anything I put in or over my ear gives me vertigo! I am always on the hunt for super light weight ear phones and these were exactly what I needed! They are super lightweight and comfortable, I don't even feel them on! The sound quality is amazing and voice calls come in really clear. As for the battery, surprisingly after a full charge, they lasted about 7 hours. The case is a charger as well. If you have that fully charged, they will charge the earphones without having to plug in! I highly recommend these earphones to anyone that likes to feel like they don't have earphones on. They sit over your ear and wrap around the back of your ear, so they are hidden as well. Also, I love that they came in rose gold, which is my absolute favorite! Great find on Amazon!

Doesn't last
I don't use these often, but after a month of having them only one ear piece works. The other one won't charge at all. Don't buy, they don't last very long.

My favorite earbuds
I love these! They don't go in my ear, so my ear canal doesn't get sweaty like they did with other styles. The rose gold color is very pretty and not overly feminine. Sound quality is better than I expected, and I rarely have any complaints while using the microphone during calls. Long lasting battery life for both the charging storage case and the earbuds. I would definitely purchase again.

Maybe I got a dud
Maybe I got a dud, but I had to return these Monster open ear AC210 headphones. On the positive side: they look great, had good sound clarity, and fit my small ears comfortably. On the negative side: the volume did not go low enough, and it made a loud beep every time I touched one of the sides to control the music, and when either earphone connected to Bluetooth. The beeps were seriously jarring. The volume would be fine if I wanted to listen to things loudly, but I wanted to use them for mediations and sleep music. If muted were a level 0 and the loudest it could go would be a 10, then the lowest level of volume before mute was at a level 4. There could have been several audible levels of lower volume, and that's what I needed. I couldn't find a way to fix either of the issues, and really didn't have time to scour online to figure out what was wrong. So back they went. I also want to point out that the listing title says they are waterproof, but the additional details say "Water Resistance Level Not Water Resistant" ...no idea which one is correct.

Parfait et facile a utiliser

The headphones are okay overall and very easy to use. Sound quality and basic functions meet expectations. However, one very annoying issue is that they stay connected to my phone even when they are in the charging box. Because of this, I sometimes thought there was something wrong with my phone when audio suddenly switched or disconnected from other devices. This issue really affects the overall experience and should be improved.

Wonderful sound quality and slick look. I love the open ear concept since I can still hear what's going on.
