My response... If your are referring to the E17K (and not the old E17) then i can now tell you that the E17K and the E18 both share the same functionality for OTG purposes. For some reason FiiO has been a bit backwards in coming forwards about this if you know what i mean, but finally i got an answer from them in my email today, i asked them for a simple yes or no answer, here is what they said in their reply... "Sorry to reply so late. Yes, the E17K wont drain the smartphones battery, as it has a battery inside, but i don't know whether it is compatible with your smartphone. As you know some smartphones are not compatible even with the E18 when it is used as a DAC. Nonetheless, the E17K has the same theoretical capability, therefore please confirm the E17K works with your phone before buying."
Well really, i must say, this is not really about the E17K or E18 being compatible with our phone, this is about if our phone has OTG capability. So there you have it folks, the truth is that this is not about the E17 or E18 functionality, they are essentially identical, and it's not good that FiiO has not been upfront about this; up till now they've been quite evasive and ambiguous about all the relative details, it would have been very easy for FiiO to just come in here and give us a straight answer, but probably they want people to pay more for the E18. Oh well, that's business I suppose.
This whole dilemma is really all about the version of Android you have. Any of the Google Nexus phones have native OTG capability from version 4.4.4 upward, and my Motorola Moto G2 with version 4.4.4 (Motorola was owned by Google when my G2 was manufactured) has OTG capability also, but this whole OTG thing is essentially software driven, not hardware. Just so every knows, Android 5.0 Lollipop has native OTG audio streaming 'built-in' with no need for a specialized app, so then that will make any phone OTG-compatible by default.

I also asked them if they can order for me if I pay in advance. They declined. Finally found one seller on AMAZON.CA cost me $225, placed my order a week before and he hasn't shipped it yet. I'm thinking of canceling order if Alpen e17 is better than e18."
My response... dude, if you still want to buy an E17K and are having a hard time getting it, i can sell you mine, it's still brand new, not a scratch on it, i've only used it for one hour total. I'll sell it to you for $150 Canadian. Just let me know.
tugsthebugs asked: "I'm newbie.. what shall I get, Fiio e18 or Alpen 2 e17? I'll be using it on Samsung galaxy note 2+Bose QC3 headphone...."
My response... I haven't heard the E18, but the reviews are not as good as i would have hoped for, that's why i didn't buy it.
However, what i can tell you is that my Yamaha headphones have been giving me a false impression during all my recent listening tests (i never would have thought so), the Yamaha MT220's are not nearly as accurate as i had been led to believe, this Yamaha headphone has been skewing my listening experience with the E17K.
I decided to take a listen through my trusty Shure SRH440 headphones, and ahhhh, a sigh of relief came to me, back in action, the Shure is much more balanced and accurate than the Yamaha MT220, so now i did my listening tests again for 2 hours here.
Now because i have been amazed at the performance of the DAC/Amp built into the 7th generation iPod Nano, i decided to do some more listening tests here, the E17K against the iPod nano back-to-back over and over again on the same parts of the same songs, A/B, and again A/B, and again A/B and on and on and on. Here's my summary...
The E17K and the iPOD Nano were giving nearly identical performance right across the audio spectrum, i'm serious! I am not lying. I used the iPod Nano on its own, direct from its line-out into my headphone. The listening tests were done at exactly the same volume level, and i had a very hard time picking the difference, that's how close it was. I had the E17K plugged into the USB port on the computer and playing the music through the DAC/Amp section so i was getting its true and unhindered pure performance, and the iPod direct into my headphone; swapping back and forth a hundred times during the same songs, they are both beautiful, the only difference was the E17K is ever so slightly warm, and i mean slightly, definitely not as warm as my Yamaha MT220 headphones had led me to believe.
Summary: The E17K is very detailed, has a nice wide soundstage, and embues a very 'mild' translucent warmth (but not to the point of annoying), and the treble range is ever so slightly recessed right at the very top-end, but not overly so. The E17K drives the sound with weight and authority and excellent timing. It is a very endearing DAC/Amp and performs beautifully and coherently. If anything it could be accused of being slightly clinical, but not in a bad way. All-in-all, for those who want a touch of warmth and have bright headphones, this thing is perfect, because the E17 dampens the natural 'snap' of the treble range ever so slightly, but not in a big way. Otherwise, on the whole, it is a very well-balanced performer, that's for sure. There is no glaringly obvious faults, and quite the contrary, it has a very nice transparent and detailed overall performance.
leobigfield asked: "I didn't understand. Did you like the e17k or not?"
Yes, now with my most recent tests, i have to say it is a very nice DAC/Amp, and the overall sound can be described as luxurious, well-balanced and nicely detailed.
Just so you know folks, the new MT220 headphones are not as accurate as the reviewers are stating, something dodgy going on here. Unless burn-in will fix things a bit, but i can't see it happening; currently the MT220 is not sounding like it should, i can tell you that much, and that has caused me a lot of misleading impressions when reviewing these DAC/Amps. I'm sorry for any trouble caused. Cheers.
