1. do not use the E11 in On mode while charging
2. if the battery failed, you can replace it with the ordinary Nokia mobile / cell phone battery.
I bought the Fiio 11 to be used with Galaxy S3.
They will be connected by 3.5mm cable.
The S3 volume is from 0 to 15. Which point should be the volume? Half way like 7?
If I put at Max volume in S3 will have distortion?
I will suggest you set the volume in S3 to 13 or 14.
maybe there will have someone who can reply you , but depend on the specification the answer is yes. note the sound quality depended on different people. and people can't just judege the sound only by the specification.
I set S3 to 12 and E11 set at 4 or 5. It's good for me.
Concern SQ, Is it better use high voltage or low voltage?
Best to test it yourself.
Depends on HP sensitivity and taste.
I think high gain is more aggressive and possibly adds a bit more dynamic range.
E11 works better with lower end HP's (Senns PX100) and IEM's, not as effective with my Senns HD595. E11 is definitely better than a HP out, regardless the player.
mind posting ur recommendations for an HP amp(excl)? as you own a Senny HD595. Budget oriented(<us$80) and portable like FiiO is ok. ibasso is little costly. just an amp is all i'm looking, not along a built-in DAC.
At that price point the E11 is probably the best bet. There is a whole thread devoted to this, check out the best sub $100 portable amp shootout. Not much more than that and the sub $200 amps are significantly better, they are also reviewed in that thread as well. The HD600 is a really nice HP enjoy.
I would use the E11 with an iPhone 5 and a new ~ $50 IEM, decent model. What should I expect from the AMP? I never used one. Is it only volume, or the sound improve? How? Why? Thanks.
Yes amps can make the volume louder, so be careful with those IEM's, beyond that they can significantly improve the quality of what you listen to, assuming the sound source is decent.
It doesn't need an amp to drive an $50 IEM.it's like 2 stages of volume booster(output gain) then....said that SQ is little improved even on some shy IEMs for sure, like detail etc BUT not as good as heard on an BD DT 770/880/990,Senny HD580/600/650/700/800 and models alike...... It's all headphone Impedance that matters to invest an HP amp to drive any power-hungry-headphones. if u own E11 already stretch ur budget for a mid-tier IEM (portable) or studio/pro grade HPs for home. it's solely ur personal preference and how it bites ur wallet.
PS:using AMP,some/most IEMs susceptible to distortion even at moderate volumes or above and also hiss because their sensitivity/VC design.
