Best Openear buds hands down!
I have tried so many of these open earbuds, but they either have a very weak sound or don't fit right. This is an exception, and they sound better than in-ear earbuds. They are very comfortable and stable and work excellent for running and workouts - highly recommended!

Sound is very good despite background noises but
But the mic is very weak it barely picks up my voice. If you want to hear music or podcasts then this is for you. But for work? I do not recommend it!

Sounds great but stopped charging
I bought this on Feb 2024 and I was happy with the sound quality and comfort. After few months one of the charging pins got stuck maybe because of the sweat after I put it inside the case. I had to buy new case and used it till Aug then one of the headset stopped charging.

Sono le uniche cuffie che non mi fanno venire mal d'orecchie o mal di testa. Comode, pratiche, facili da usare, la batteria dura lungo, il suono è più che discreto. Si può parlare camminando per strada tranquillamente, anche in mezzo al traffico. Questo è il secondo paio che prendo sono davvero ottime spero continueranno a produrle.

It’s one of the best products I’ve ever bought. Sound quality for listening and receiving during closed or indoor activities is almost 100% excellent. For outdoor use, it depends on the surrounding activity—for example, in a windy environment, the person listening to you may complain that they cannot hear you clearly. What I like most about it is that it never falls off, and this is exactly why I chose this product. Finally, compared to its price, it’s an excellent product overall.
