EX71
- bass very aggresive & exaggerated, while mid band is flat...good for bass-craze crowds...
- sounds much better than most earphones at the same or lower price point
EX81
- warmer, richer, deeper sound to a crisp and accurate one
- bass is tuned down
- not as details as those S$300+ canal type earphone...but it will please most ppl who appreciate good sound & dun wanna sacrifice bass...
if ur choosing between these 2, i say go for EX81...but make sure ur comfortable with the ear hook.
but if u want to get the best outta ur mp3 player, go for Shure E3c and E2c...
i'm personally using EX71 for quite long already & quite content with it...
