Well to be honest the audio is good but not better than JBL. But if you use equalizer the audio comes out great . The USP i felt of these earphones is that these are very durable , the wire is thick and strong enough and the earpieces are made out of metal which looks and feels strong enough . Well in this price range i have used all the earphones including the JBL C100SI , the Senheiser CX180 , The house of Marley Smile Jamaica even the Boat ones. These arr the best you can get if you want Durability. But if you want better audio quality , go for the JBL ones. I posted because i felt i should share this information as i have used all of the earphones in this price range.
Update : 7 months and they are still working great . No complaints till now.
