The Preview of a "Pink Floyd CD" with headphones surprised me very positively. To expect a balanced sound image with a slight overstatement of the bass range. This is however, in my opinion, within the tolerance range can be combined with a few settings on the equalizer of the mobile phone largely correct. I can also imagine that this effect from manufacturer target group is deliberate, because just put teenagers on bass dominance value me.
Also I was surprised by the sound momentum of headphones. The small in-ear headphones sound almost as large on-Ears and the sound has a volume that you would not expect in a small orchestra.
Strong buy recommendation!
