I be sorely disappoint with these earphone . at first I be pretty excite about they ; they seem to be work great -- I buy they to replace a pair of iFrogz earphone that suddenly stop work . after about two month I start have the same problem with these as I do with my previous earphone . I have music on , and midsong , the earphone stop work . I could hear the music fine , but the singer be so fade out that I could not even hear the word . it sound almost like I be listen to someone sing underwater . this be the same thing that happen with my last earphone . I be very upset that I spend the money on these only to have they break on I . I would not recommend buy these .
