Better than Bose, Sony, nuraphones, and any other company. I havent cleaned them (Im terrible with shoes. Very easy to put together and install. I called Chaco about this concern, and they confirmed their design is now different. it is definitely what you are looking for. Der Innendurchmesser der Lauscher beträgt etwa 3,5 cm x 6,5 cm. The quality is good in itself, I had another pair of wireless earphones and it made me unsure if I should buy another pair as the sound quality want good, but these are amazing.
