Boasting micro - sized Balanced Armature full range driver units, it delivers an incredibly balanced spectrum of sound - from the highest highs to the lowest lows - at a fraction of the size of traditional drivers.

great sound detail


from Undisclosed

For all those who complain about the lack of bass, try to use the extra small earbud (red ones) in the package and stick them well in the ear. The bass will be perfect, detailed and punchy. Also the mids will be better. I use them on my HTC One X with Beats Audio turned on.
