AK120 was my first dap. Liked the warm sound with vocals. As AK jr has the same Wolfson chip I might get one as it's more portable as AK120.

Its now 10 months since i got the Mojo.. But i keep finding myself grabbing my good old AK120. I cant get used of Mojo,s recessed soundstage. 120's dual chips really feels like freeing the sound while maintaining warmth.
Just discovered using Musi on my iphone4/AK120 combo. Its a YouTube audio streamer which allows the screen to be turned off. And no interuptions by commercials (i did pay to lose the banners though) really a recommendation to try.
I even find it to render a good amount of bass on my stock AK. Same as Hiby.
Note that Musi is only available on ios. Well i didnt got my AK's Dac mode to work with android at all anyway.

how long are everyone's battery lasting? When should I replace? I feel like my ak120 titan is only getting about 4 hours every charge
Not that long unfortunately, mine was about 6 hours after 18 months.

Unfortunately, A&K doesn't really implement high quality batteries, they tend to lose 25% charge at around 250 cycles and around 50% charge at around 500 cycles.
Try a Sony DAP or smartphone, and you'll appreciate the battery longevity life in terms of cycles.
I can keep my Sony phone/tablet off for 6 months and power it back with 98% charge. Try the same with an A&K DAP and you'll get a very empty battery.
A high quality battery is a battery with very low leakage.

My ak120 titan lasts for 6,7 hours after 3 years, which I consider very acceptable. Have no idea how many charge cycles it has but I’m not using it every day. One thing for sure, never noticed the battery leaking when not in use.

Leakage is not the worst ever with AK120, but it's far from being brilliant either.

If you don't use your AK120 every day, you're probably not burning through cycles very fast.
I charged mine every other day, and 250 cycles were gone in about 19 months. A bit more than 3 years would be 500 cycles.
It seems that your battery is still well below 500 cycles. :wink:
