They are an extremely clear sounding set. Definitely a brand I would buy again. I was concerned this might result in rubbing in this area, however, after a week of use, that included emersion in salt water and then a walk of 2km, that concern seems unfounded. ive had other yoga mat flip flops but these dont sweat your feet and the others will wear out quickly becoming flat but these are very comfortable and I have plantar facitis and they feel great! I love the adjustable Velcro strap across the top to tighten the fit. The one thing Ill say is that the footbed is a tiny bit narrow. I guess i will still have to use my old lock cable. Im not going to pick my phone from my pocket every time I want to do something. le son est vraiment propre, les basses sont présentes et nettes sans empiéter sur le reste du spectre, les aigus sont tout aussi clair et aucune distorsion ne se fait entendre. I know it’s a refurbished item but the speaker will not charge.
