Been a long time since the last time I bought a device which specifically use for playing music. I remember having a usb stick mp3 player that I loved long time ago. I broke the thing then I start to use my phone as a music player ever since. Take note that I never have or even tried any expensive DAP (such as AK's line of DAP). I have my Ipod Shuffle but I stopped using it because it cannot play FLAC and I hate using iTunes to transfer files, so annoying, but I personally love the Ipod Shuffle sound signature and everything (except that you can only shuffle song and nothing else).
I got my phone (Sony Xperia Z1 Compact) broken on the 3.5mm jack so whenever I move around the music stopped, so I was looking for a temporary cheap music player that can play my flac files and that's when FiiO release the M3 (I've been eyeing for X5 by the way but still counting on my budget whether I actually need it or not, so M3 is a good bargain)

Side by side with E17k
Okay enough with the pre-story, now down to the review
Once again this is mostly what I like and dislike with my purchase of FiiO M3, you can agree or not. If you are ok with it, please proceed
Design & Build Quality
What I Like:
I love how small it is, it doesn't take any place or whatsoever. It is very lightweight and you can toss it around without worrying it will break. The body made from plastic (as expected by the price, but I wish it was made of alumunium, just like my E17k) but it is a good quality plastic that I feel it won't get easily cracked. Screen is okay, I won't say it good or ugly, but I don't have problem with it. The color selection is NONE. It coming in Ivory color with a black front panel. I would be very happy if it was black.
One thing I like that surprise me from it (because I dont expect it at all) it is compatible with any headphone with In-Line Music Control. Yes! You can skip file, Forward, Previous with just a click from your In-Line Control. You don't have to reach your pocket to skip songs. But somehow since the FW 1.5 it doesn't work with my Vmoda M100 anymore but still working with my Momentum In-Ear I wonder why.
What I Don't Like:
UI
One thing that irritate me the most is the screen won't turned on whenever I press the front control, I still need to turn the screen separately whenever I want to access the menu. Well, one click less hustle than two, right?
Well, I have mentioned about the volume control above.
The rest of it I'm good with the UI.
One thing I wish from the custom equalizer is more audio bands selection instead of just 5. I have this filthy Sennheiser Momentum In-Ear which is very ugly sounding until I tweaked the equalizer (on my Xperia) and it is so much harder to get the perfect sound with the current bands selection. Upgrade FW please??
Sound Quality
This part would be very subjective for every person, so take precautious with my impression.
I will compare it with my FiiO E17k which I use by daily basis.
Coming out from the E17k, FiiO M3 have more emerging detail in the higher mids to lower highs.
Sound impression would have a tendency with the highs. Something with a lot of textured sibilance. The highs is grainy, especially in the vocal. So if you don't like sibilance (like me) I would recommend you to take audition first, but depends on your gear I think sound quality would be work just fine. I will say that base is okay, it's relatively flat IMO.
Overall, I still prefer my E17k instead of M3 in term of sound signature but it is more than twice the price so what can I say? LoL
It doesn't support USB out DAC (I tried it with my E17k) so you might only be able to use Aux for Amplification only
I bought it so I can play FLAC files so I don't have much expectation from it because it is a good bargain. The screen is a good bargain compared with Sansa Clip or some other players.
So far I don't encounter any problems like heat or hangs, everything works just fine. One annoying thing is I got some songs not supported with it, I believe it is a High Res 96/24bit music.
Take note that I notice my 44/24bits files can be played but displayed 44/16 instead. I don't know it is a downgrade or not, but since it is still playable I'm okay. Anyway I bought it not for some serious listening session but for mobile on the road.
Overall:
In terms of DAP i believe there's a lot of other better in term of sound quality, but in terms of feature, price, file compatibility, mobility, FiiO M3 something that you would considered for.
PTP Ration I give it 8 out of 10. Well done, but still have a lots of room to improve.
NB: It come out with some good bundle of accessories such as Straps, Screen Protector, and Earbuds. What? Yeah you read it right earbuds. The earbuds sound great paired with the M3. Not a fan of earbuds but it is a good companion (I would much prefer IEM for the sound isolation and comfort reason)

What I Don't Like:
- Volume Control Button. I love the mechanical volume button, but I like it independent on the side better... instead of in front, I like it on the side (so in the front would only be Prev,Play/Pause, Next) It still okay anyway, but the most irritating thing about the volume control is you need to be in the music playing interface to change the volume so whenever I want to change the volume while costumizing my equalizer I need to go 'outside' ga back and front, so much hustle.
- A bit crampy down there. Got what I meant? Yeah, I know that size comes with price but I just realize that price a little bit too high. I will take comparison with the Ipod Shuffle which I don't have much problem with control.
- Edgy Design. I wish instead of exact square shape, it better have a rounded edge, I prefer it aesthetically.
- Strap Hole. It is good to have a strap or something so you can put it somewhere when you don't have any pocket, but I wish instead of strap I would like a clip better, more practical for me because for e.g if you want to jog with it, having something around your neck swinging while running isn't a good experience IMO. By the way, why the hole need to be down there? Now whenever I hang it, the headphone jack would be lying awkwardly (I wish it will be in the opposite direction from the headphone jack)

Sorry to hear, that you found them uncomfortable, I myself did find them very comfy and could wear them for hours.
As for replacementparts, the earpads are easy to take off the headphone. Pro-Ject also sells a rounder kind of pads...
