wow, did i read it correctly? 100+ hours w/o charging is really amazing battery performance.
Wonder what is your source to run in this amp? ipod. cd or radio?
(I thought ipod can only run 20-30 hours on battery)
Also, what is your headphone/iem? Maybe the cans driver is very sensitive and consumes less battery juice.
yap.. from ipod 100h+ i get from accumulation, each the ipod need recharge, my touch can go around 41-47h per charge, so after 2 time charge the ipod, than the amp give up... around 100h+

i'm using westone 3
after charging i tried the .25 battery life
once again... this time running on my pc, that never shut down, and repeat the foobar playlist...
and the result i about the same, last night the .25 is still on, and it's already running about 107h+ continuously , but when i wake up this morning, it's already turn off...

so minimal battery life that i get 107h... plus ... don't know how many hours the.25 still play until it run out battery when i sleep

i'm using westone 3 also for this test...
