I'll make this clear - the sound signature of these headphones will not blow you away. I was expecting a lot from these (after reading the many positive reviews) and when i first listened to them i felt a little underwhelmed.
 
We've all had that experience where we listen to a piece of music and think...meh it's ok - and then months later you're putting in your top 10 all time favourite list. Well i've had the same experience with these cans. I have grown to love them!
 
 
Design - They're lightweight, surprisingly portable and have a minimal look and feel. They can be used as DJ headphones due to their tilt cup design (the left headphone can be tilted away from the ear). They are also modular which means you can replace the parts if they ever go wrong.
 
Comfort - At first these things did hurt my head and gave me a bit of ear ache when listening for long periods. However after about a month of use, the comfort significantly increased. The clamping force became much less intense and i can now wear them for many hours.
 
Sound Quality - As i've already mentioned, the audio quality will not blow you away. These are a neutral set of cans with an emphasis on detail and clarity. The sound stage is lacking and some tracks can sound a little flat. At first i thought this was a bad thing, but soon i began to appreciate the purity in the sound that these headphones offer. Give them high quality audio and you will hear every bit of detail. What puts the icing on the cake though is the instrument separation - this is what these headphones do best and at very high volumes too (i sometimes DJ in a club where the booth is ridiculously loud and no matter what the volume is - i can always make out the low, mid and high without any bleeding of the sound).
 
Bass - A little more emphasis here, but they never overwhelming and sound punchy rather than warm
Mid - Clear and neutral in texture
High - Clear without sounding bright (not fatiguing on the ears)
 
These headphones are great for electronic music (house, techno, tech-house) and sound great with older flavours too (trance, progressive etc.)
 
Value - Not that cheap and even though they're modular in design, the parts are pretty expensive. However these things are build like a tank, so in my opinion they justify the price tag.
 
 
9/10 - i absolutely love these headphones and recommend them to anyone who is looking for a closed back design.

I paid around $120 for this device and felt pretty underwhelmed by it's performance.
 
At work, i use a bog standard dell pc with an on board sound card (which one would presume is not of great quality). When i plugged in the DragonFly - I noticed a slight (and i mean ever so slight) difference in sound but I could not tell if that was a good thing or not. It certainly sounded a little different, but did it sound better? I'm not so sure.
 
I have a variety of different headphones:
 
HiFiMan RE-400
Sennheiser hd 25
HiSound-Audio Crystal
 
And to my ears i could not hear a noticeable difference in sound quality. I compared the device to my Macbook Pro and (in my opinion) the Macbook actually sounds slightly better (the sound stage is wider and the bass is punchier).
 
I wanted to like the Dragonfly - it's well made and looks nice plugged into my computer. However for the price it was just not worth it. Spending the money on some improved headphones would have been more worth while.
 
I cannot recommend this device based on my experience. Would be great to hear the thoughts of others if they have owned this device.
