Im 53" 165 lbs, hippy. They are comfortable and not nearly as heavy as the standard sandal. It made hiking very difficult as sole would slip on virtually anything after the shoe is wet. Posso dizer por experiencia propria, já usei a garantia da logitech em outro produto, é a melhor garantia que já vi, não há complicação. To me these get the job done and are comfortable at almost 1/10th the price of big brand over-ear headphones. Practico y protege She says they?re very comfy and feel good. If the quality doesnt hold up, I will update the review. The IE40 pro has similar sound unit as momentum in ear. My feet wasn?t to tight it was more like a comfortable tight my foot didn?t slide either.
