Negative Positive
Title: Good sound, very poor quality.
Review: My first set after a fair amount of use gave up. Because the sound quality and sound isolation is good I bought a second set. After very little use they quit working. They can't be fixed, even by the manufacturer, and the warranty is useless. Replacing the filters is also a hassle and expensive. Not recommended when there are so many other choices out there. I feel like I wasted $80.00.
