When I first wore them I was disappointed with the sound. Almost zero bass. Somewhere I read in a review on Amazon to change the eartips to improve the sound. Indeed, they were a bit loose in my ears. As soon as I put on the larger cushions that came as spares, transformation. The sound gained body. The bass started to be heard and there was better passive isolation from external noise. Although I am a fan of the company for what they offer sonically regarding music, they are expensive. They are not better than the JBL-T110. In a test with YouTube video calls, they performed well. In phone calls, people hear me perfectly. The materials seem to be of good quality. In conclusion, 3 stars to 3.5.

For this price, it's the best. Excellent sound, far better in this category with very good external noise isolation [I wear them and work with them] very good fit with high-level silicone and design, and very good reception on the radio. In Motorola g72, the sound is truly magical. Purchased from Nacca and impeccable service at all levels! Having gone through at least 30 pairs of every brand due to work, I highly recommend these and I think you will love them just like I do!
