i agree, i use my E12 to easily power my HE400i with my X5..

 

[Chris J]

So what that means is that I can use the line input as an output if im using the DAC and connect the e12 to the line output?

Yeah, that's right.
You can cable the "Line In/Out" on the E18 into the "Line In" on the E12 if you are using the E18 as a DAC.

Hey guys I have a pairing question, I see people pairing an e12 with a fiio X5, and I thought of something.  Since the X5 at 32 ohms is about 300mw of power and people feed that into the e12, i was wondering if i could do galaxy s4 --> e18 --> e12.  Since the output of the e18 is about 350mw of power, i think it wouldnt hurt the amp.  The reason i want to do this is because i love the sound quality of the dac in the e18, but dont have an extra external dac and need more power.  So my question is, can i go from S4 --> e18 --> e12 --> or is it bad for the e12?

I noticed this question was kinda left hanging there.....
If you did plug the headphone jack on the E18 into the "Line In" on the E12 you wouldn't actually damage the E12.
The "Line In" on the E12 would not actually pull 350 mW out of the E18.

But the best way to run E18 into E12 is the E18 "Line In/Out" in the E12 "Line In".

  It has a dual purpose jack that is a line input if the USB/DAC is not in use which serves as a line out when the USB/DAC is used,

Yes, I've done this and it works.

Ok thanks guys that just made my life a lot easier

Does E12 v1 has any real collectable value since it was manufactured in a limited quantity of 200 units for Chinese market only?

 

[Evshrug]

Well, "collectable" is determined by demand. It was also released in limited quantities in the US, I got super lucky to get a "OG" E12 from pre-market launch. You can tell if it's the first release because the silks teeming for the gain selector says "10 dB," even though internally the gain is a 17 dB boost. My opinion is it is the more desirable version since the bass boost is centered at 20 Hz, REALLY low bass. Both the current and first E12's have a 6 dB bass boost, but the first E12's boost the bass where most open headphones are pretty rolled off, so it is more of a bass "extender" and doesn't bleed at all into mids, very clean and atmospheric.

  How do I know when the E12 is charged fully? Will it hurt the battery to keep it plugged in indefinitely? Thanks.

 

[bms44974]

the LED will stop flashing. I do not know if leaving it plugged in will affect performance or batter life.

 

[Chris J]

Battery should be charged and discharged periodically.

But if you have it plugged in all the time, who cares about battery life?

 

[campj]

I'm not sure why I was quoted, I posted that over a year ago. My E12 has been sold and gone for nearly six months.

It doesn't harm to leave it plugged. All decent battery powered electronics has a $0.1 chip which regulates the charging.
I leave mine plugged for long time.
What I noticed, is that led continue to pulse, while turned on. Immediately after I turn it off, it does a couple more pulses, than goes fixed.

That's probably a trickle charge to keep your battery topped off.

Hey guys I finally finished my portable setup with the e12 and I'm using the JVC HA-SZ2000. Its terrific, the sound is amazing and the bass is great. I'm planning on getting the Grado sr80e's in January. But what I'm wondering is what other headphones would you use with the fiio e12's.
 
My setup is this: Fiio X5 > HS6 Line out > Fiio e12 > JVC HA-SZ2000. What other headphones would you use that would sound great and bass would be booming?

So I purchased this amp used a few days ago and got it today. Something I'm noticing is that the volume dial is very tight. I've read that it's tight in reviews, but I didn't expect it to be quite like this. Is it supposed to be really tight? Also is the volume pot meant to be removable? It comes off on mine, revealing just the metal rod.

 

[HotIce]

It is tight, as you do not want to be turning accidentally.
Should not come off easily though, even if yes, it is removable.
