dont mean to mislead u immitbiker
i always want a er4p for their clear sound etc not the bass, tf10 is pretty all rounded but at this stage before i do some comparison it just not for me so i might keep RE0 and get a headphone for the bass purpose~ eventually i m gonna get headphone any way~ right now i m leaning toward HD650/HD800/DT990 600 ohm
if i travel to asia next year then i might look for AKG etc
until i hear grado then i will decide but at this stage grado is out because i dont think the built quality match the price~ and the customer getting enough respect judging by un-even built quality

u can have fang do his best to finalize the quality without compromise or you could pay over 1000+ for grado and not getting the quality for the price. so grado have not earn my respect yet ( then again i havent hear it)
