After buying a first set of Klipsch X10i headphones, extremely light and lived 18 months, I bought a pair that lasted six months .... I decided to take a cheaper model (Because 120 ca pair was getting a lot) and this time they did not keep more than 20 days ... I am going to send an email to klipsch to complain about this lack of quality for such price. I am very careful but it is not enough ... So be very careful.
