Headphone was absolutely fine.
However not satisfied with the product.
I used sanheiser cx 180 previously. That was very good at performance. The high notes and lows were very soft and smooth bass was very apt. Bass of these earphones are good but Treble is more as you increase the volume. Its better if you keep them at low volumes by that you can get good output.
This product jbl dosent set that standards. Hence returned this product.
M not saying this is the worst but.
It is definitely good for rock and classic.
