I do not need any orthodic insert and I have had no pain or swelling at all! My only concern is that it may not be made to throw up your wet shoes from the rain or snow, but I do think its somewhat tolerant to water. Im also not a person who does much mechanical work. BATTERIA -> direi ottima, con un ora continua di ascolto gli auricolari sono scesi solo del 20%, con una carica completa del case si ricaricano fino a 3 volte gli auricolari quindi direi che se si usano costantemente si fa almeno una settimana. --- Rather rough/grindy-teeth feedback when cornering, not like a real steering input/feel. It’s made weird and it feels a bit cheap. Also could not make any equalizer or base adjustments. I bought my first pair and literally wore the soles out on them so I looked for them online and found them here. 9/10 - just because I found bigger bottles at Costco for a lower price. I am returning them for size 9-10.
