I’ve owned an HX550, H15, and Boom2 - all are Motorola. I tried these out as an alternative to the more expensive AirPods. The inner dividers are less than paper thin plastic and the shell is thin material. One thing that was slightly confusing was the instructions, they weren’t the most straight forward but by no means is it difficult. das. Seem really well made and he really likes the design and I’m sure he’ll want a new pair once he’s grown out of them. I highly recommend this headset to everyone. The sound quality wasnt nearly as good as my Bose SportSound earbuds. I didnt hear that note before. I bought these recently and love the quality and the authenticity.
