It’s definitely not heavy duty, it for the price it’s alright. The skates are good, the sensor is flawless, the buttons are very good (a little bit on the clicky side but I like it that way) the side buttons have a little bit of play but thats all. Produit non conforme à la photo, livré sans lattache arrière du coup il ne tient pas aux pieds de ma fille. You also need to buy a fast charger and longer USB C to USB C on the new Apple charger. I might give it one more try before dumping it into trash but this didnt help my BP but made it worse. Bottom line is, if I had normal feet that were average or narrow width, I think these might have been comfortable after a short breaking in period. Now I have to order a second pair after 5 weeks of use. Poor quality for the money spent. Also, I have never used a high-end and much more expensive ANC headphone (reason is that most of them are not bluetooth which is what I need). Also helped with dry scalp as well.
