Very comfotable and solid sound quality

Just received them, and compared to oladance 2 and Cleer Arc sport 2, these are very competitive indeed. Much more comfortable than both of them, with good sound across the range. Will be testing out more and add to this review over the next few weeeks.

4.0 out of 5 stars The fit & ambient sound won’t work for everybody

Good sound quality, good call/microphone quality, but the fit can be hard to get used to, and there’s always ambient sound with no way to “noise cancel” or block out surrounding sounds. *Comfort* The fit of these takes some getting used to. The biggest difference I noticed is that the ear tips do not fit snugly inside your ear, sealing into place, the way most rubber ear tip earbuds do. The earbuds are held in place with the wire that wraps around your ear, and the ear tips kind of just sit outside your ear canal. The ear tips also have holes in them, for airflow and ambient sound reasons. It works but feels a little odd. They’re fine for short term wear (less than an hour at a time) but can get very uncomfortable if you want to wear for long periods of time. Because they hook around your ears, and the ear tips don’t seal snuggly into the ear the way most runner tip earbuds do, my ears get sore if I wear these for too long. The arms that hook around the ears just get too uncomfortable after a time. *Hear surrounding sounds* These earbuds let you hear ambient sounds, but you can’t “turn off” the feature, because it’s not a setting- is just that the earbuds tips don’t seal into your ear, and they holes in them, so they don’t block out noise from around you. It’s easy to hear your surrounding environment while using these earbuds. This is great for safety if you’re jogging and want to hear incoming cars, but terrible for somewhere like the gym, where you’d rather block out the noise and just listen to your audio. *Phone Calls* The sound quality is really nice for phone calls. When I call somebody, they never hear their voice echoing back, even with the volume turned way up. The audio stays crisp and clear, and the microphone does a great job picking up my voice.

These open-fit earbuds are the first earbuds that don't cause discomfort in my ears! Truly pain-free

These earbuds are AMAZING; exactly what I’ve been looking for over the past few years. I’ve always found that most earbuds, from AirPods to over-ear Beats, tend to cause discomfort in my ears within the first ten minutes of use. When I saw these earbuds, with their unique shape, I was rather intrigued and decided to give them a try. A GAME-CHANGER, I tell you. The earbuds rest just outside of your ear, ensuring a pain-free experience – and if I hadn’t tried these for myself, I would have expected the output to lack the crispness of typical earbuds. But despite the lack of an in-ear portion, I’ve found that’s not the case. Now, I’m not an audiophile; more of an average listener, so take my words with a grain of salt unless you too are an average listener. Even after a long call, I experienced zero discomfort, and I was shocked. Each earbud magnetically snaps into their slot of the charging case, which also serves as a sleek, convenient storage solution. I’ve found the battery life to be impressive as well. Overall, I could not be happier with these. I’m SO glad I decided to try them. They are ideal for unending work calls, Zoom meetings, or listening to music without disturbing anyone else in the house. Pairing these via Bluetooth to different devices is actually a breeze; it’s so intuitive that I didn’t even need the manual the first time around. They feel well-made and durable, so I think they’ll last me for quite a while. Highly recommend!

Excellent Sound Quality

These are the best pair of earbuds I've ever had. They even beat my AirPods. The sound is so clear and crisp. After the first setup, these will connect to your device automatically as soon as the case is open. These charge in about 30 minutes. It came with a USB cord, extra tips, and a manual. These are so very comfortable to wear. I can't even tell I'm wearing them. They are so light. The best part for me is they actually stay in my ears no matter what I'm doing. These are excellent quality.

Although the sound is clear and clean

I have tried a LOT of open earbuds - Oladance Pro, OWS2, Shokz Openfit and these are by far the best ones. They are like a pair of open fit but with great sound. I can understand that the fit is not for everyone as the ear hook can be a bit tight but on me they are perfect. I can work out like crazy and they don't budge. I will try go on a bike trip later to see how they perform there but I have high expectations. These are open-ear designs, so if you want to block out your surroundings, these are not for you - that is the point... I commute by bike and you need to hear your surroundings or you.. I so really looking forward to taking these for a spin because the sound is really really good for a pair of open ear. Oladance Pro might be a tad better but they cost 150 euro more. Oladance OWS2 falls off my ear when you benchpress or do situps, so don't go there.
