The original HF that come with the phone are not too good for muzic... it's not laud and no bass at all.
There can be 3 ways (that I know ;) ) to solve it:
1. Use 3.5 mm adapter to any other quality HF, but without option to answer the calls.
2. Use iDNA MRH-300 remote control with 3.5 mm adapter to any HF you like, with full control of media player and call answering option.
3. HPM-82, same as MRH-300, but for my opinion, worse sound quality and less comfortable (no joystick and Hold button).
