These started as great headphones, but the sound quality was just acceptable. However within a month, the sound started deteriorating, when used as a phone, calls started getting dropped or sound started becoming intermittent. Now it's 3 months later and we're looking for a new set of headphones. Definitely not buying this one again. Maybe it was a chance defective item, but I'm definitely not satisfied with them.
