on a full charge, does the amp last for hours of listening or is it a shorter charge, like an hour or so?

On a full charge, and, for me, I had it on the third setting (Blue) on constantly, onto my iPod, it last around 6 hours! So, if you want to run it for a long time. Quick charge during lunch breaks, coffee breaks, and so on.

The specs say it should last about 5 hours, but it's even better than that for me. With my headphones (Bose AE2) on the "blue" setting (bumped-up bass, i.e. high power output), the amp will last a full work day (8 hours). So, for me at least, it's "hours of listening".

I have not personally had the unit stop based on a low battery. However, I have never timed it. I carry it along with a USB power block to keep up power to my player and the FiiO during plane flights. It works well in this mode as it provides sufficient volume to overcome noise on the flight. I have been very satisfied with the unit as it small and gets the job done.

a new battery lasts 8 - 10 hrs when fully charged. don't waste your money on the fiio e05 or e06 (both $30), because they only amplify 30%. try instead the fiio e11 ($60) which doubles sound volume.

I use mine daily, and if I forget to charge it up, it dies after about 10-12 hours of use. So for an 8 hour work shift, you should have no problems at all! When you charge it, a red indicator light goes on. Mine seems to go out, meaning it's fully charged, after about 2 hours.

I have not used it in several months, but it seem like it would last for several hours.

Battery life is around 10 hours - yes you can listen while charging, but only if you have a USB charger (not PC connected) - the cable that comes with it goes to your PC, which charges and syncs but no listening while syncing

I listen to audiobooks so it's as many as 8-12hours/day. I also wait until it tells me "low battery" before recharging completely. That seems to insure that each charge provides me 16-20 hours of listening. I charge about every two days.

Mine only lasted barely an hour with ipod at 3/4 volume and the NuForce amp set on low. It may be defective so I don't know for sure. Product description says battery included. From what I gather it is not user assessable. I may return it after 3 trials of overnight full charge and doesn't last more than an hour.

I get between 10 and 12 hours. It depends on the type of music...bass heavy music drains it faster.

With a new charge, and constant use. You will get a solid 4 hours of play. Though Ive tried it as a hands free in the car, i do not know if that would affect its battery life. Ive used it for listening to music.

I can listen to a music/radio at work for two days straight (18 hours total) and still have battery life left. I've never tried to go three days without recharging, but I might be able to do so. I have noticed that because of the pause/playback feature, listening to the radio tends to use more battery time than listening to MP3's.

I've only used at moderate volume levels; plug in my acoustic bass so that I can keep up with acoustic guitars that would otherwise over-power the bass. On another (unrelated) note - the battery life is nowhere near what is being claimed, I'd say about 6-9 hours max. Good enough, but definitely way less than the 75 hours they claim.

It just depends on how loud you have it. I sometimes make it two 8 hours shifts before I have to charge mine!

I get 7-8 hours of continuous audio out of mine! I listen to talk mostly, so maybe less bass = more battery? I dunno, but I've been through several pairs and always get, at least the 7 hours the nice lady inside the headphones says I'll get.

I haven't used it for 20 hours but I think it probably would. Maybe not if you were cranking it up all the way but I don't know. But it is a nice little amp.

not sure the exact time , but i listen to audio books and it has lasted well over an hour when fully charged. most of the time i just leave the cord plugged in.

In the short amount of time I used it, I only charged it overnight once. I probably listed 6+ hours and still was working good. The only thing was the sound quality.

Not sure. I used it on/off for 4 hours. It last longer than my cell phone battery used as the music source.

Thanks for your question. HiFiMan states that the battery should last about 15 hours and it depends on the volume that the unit is playing back at. Takes about 2 hours to charge. You can charge it either way. This is a fantastic sounding player. World Wide Stereo is 36 years old and a very proud HiFIMan dealer.

No, it lasts closer to 4 1/2 hours on a full charge. I have never gotten more than that out of it.

I have never used it past 3 hrs and there was no problem ...The company says a full charge can play for 5 hrs .. With a lot more hrs standby.
