Thanks for the quick reply, I am now definitely considering getting them. Only trouble is I can't have all my music in lossless... damn 16gb!
Almost all Li-ion battery from China is overrated for their capacity. So far, I am happy with the one from BXT. It said 2050mAH but but it is more like 1400mAH. Still better than the stock at least. Got another battery from Andida which is totally suck.
Thinking of getting one of these for my portable use. It's going to a Fuzev2 rockboxed no EQ>E11>ATH-M50. I'm currently using this combo with an E6 but it sounds very changed signature wise and mine is also starting to die it seems like so i figured an upgrade( if this is) wouldn't hurt. music of my music is FLAC or mp3 320 CBR out of the fuze for reference.
watch out we got another one comin, E11K - built-in battery.....no more user replaceable.
