Great purchase Shripad ! A decent upgrade from M2 . Just take good care of them cause out of 3 I got (friends + TE members) , 2 of them died . NuForce later admitted that there were quality issues with the cable and they have improved on it in the second revision but your doesn't look like the new revision .Shripad said:Another great sub $100 IEMs (Nuforce NE 700X). My 4th set this year (need to stop) after M1, M2 and ATH M50.
Worth every single penny.
