Hello, my experience in portable audio is quite limited. I've never listened to anything better than iPod and some budget earphones. Needless to say, the sound I got wasn't really impressive. Than I decided I need to have some dignity and bought myself Senn HD280 and Rocoo P. Needless to say it changed my view of music.
Unfortunately, I had to sell both. The player turned out to crucially lack bass which was a hardware change, and the headphones squeezed my head like a toothpaste tube. But I just couldn't forget the wide, clear soundstage and the instruments which sounded actually like real ones.
So, now I've decided to try to put up a good portable rig again. Well, I'm not really going to listen to it on the subway or something like that, I just don't want to be bound to one place with a desktop DAC and be able to take it somewhere.
Unfortunately there are VERY little places I can test any headphones where I live, and the selection there is pretty limited. So I just want to decide what to buy right now and do it straight away.
My dream set up is planned to look like:
Android tablet (USB Audio confirmed) -> USB DAC via OTG cable -> headphones / earphones.
I want: 1) good, powerful, natural and clear sound in general (really tired of hissing growl of budget in-ears where you can't tell one note from another on high volume) 2) wide soundstage, 3) comfort.
What I listen to: mostly indie, alternative, punk and rock.
My current contenders are Beyerdynamic DT 770 PRO (I'll probably choose them), Sennheiser HD598 (plan B) and Sony XBA-3.
On the point 1: It's decided that I need a good portable DAC/amp. But which one do I choose? I was really going for AudioQuest Dragonfly, but I've read mixed opinions on the quality of sound. Not only that, it turns out someone on the internet tried it with Nexus 7 '2013 which I have and it didn't work. So now I'm thinking about either Fiio E17/18 or DACport LX because someone said it's great.
Buuut will I even notice the difference betwen them with entry-level headphones or in-ears?
And what combo do I even choose? Am I better off with high-impedance headphones and a powerful amp or something around 50 ohm is enough?
2. And here I have a big misunderstanding. I don't actually need to feel like I'm standing on the top of some mountain listening to a song and the guitar is playing from another mountain 1km to the north and the drums are banging are 2km to the south, but every pair of under-50$ in-ears I tried sounded like all the instruments got mixed up and played from the same place which was pretty lame.
So, are headphones my only hope then? Am I bound to get instruments mixed up with in-ears, or only the size of the soundstage will suffer? Does that still apply to armature ones like Sony XBA-3 and such? If not, I'll think more about getting some in-ears.
3. Why I'm in doubt about getting headphones? Comfort is the issue. From the threads on comfort I've read here, the most comfy entry level/lower mid-range headphones are Senns HD5958/598 or 650, AKG240, and most notably, Beyerdynamics DT770. The only thing I fear is that I'll get my head strained a lot. As far as I'm concerned DT770 is a safe bet. But do they perform well, because I haven't found them in the current HF buying guide? And, to repeat the question, which one do I buy, 80 or 250 ohm? They cost the same, from what I've read they perform with amps about the same, what's the difference?
