They went through the washer and dryer and still works. They are some of the best sounding headphones i've ever listened to. i've gone through a ton of earbuds and none of them have lasted as long as these have. the sound quality is really good! After a month one of the ears stopped working... but i realized that it was just my earwax that got clogged... so it was easy to clear out
Output:
positive
