I have been using this product for over a year now. The sound quality and wire quality and noise cancellation are excellent and worth the money you spend. However, it doesn’t have mic, volume controller or music changing button which is a big let down in this earbud! One cannot use it for calling purpose as it lacks mic. One cannot enjoy listening to music with it either as it fails to fulfill even the basic requirement of a headphone or earbud, i.e., volume controller or at least a music changer key which is a disadvantage considering it’s price of approx Rs 800!
However, after experiencing it’s sound quality, one can simply ignore these cons!
