You most likely will not need an amp with the 80ohm version unless you like to damage your hearing.

Once I threw them on a decent headphone amp I was relieved that the mids weren't as recessed as I had feared, and the whole sound became much more lush and balanced

I think getting a cheap (sub $50) amp would be worth it, but not a necessity

I'm using the FiiO E6 portable amp and it is amazing with these headphones.

If you can get a decent amp maybe 50$ you will find that these headphones are unbeatable when it comes to monitor tracking and producing music

If you plan on doing any computer/mobile listening with these guys, then I really recommend an external amp

Second of all, these are very comfortable, you will have no problems with the comfort.3rd, these things can be used as portable cans (don't advise it) but you need an amp, like a fiio E11, and you need to rap the cable up with something like a rubber band

That's the thing with good headphones and amps; you have to feed the beast

I purchased a FiiO A3 portable amp

so don't expect great sound coming from these without a proper amp; especially if you're using a mobile device to drive them

He stated that they need a portable amp to get the best quality sound, in his opinion, but overall the headphones are comfortable and the sound is excellent

The Lycan is a transparent amp and will let you hear the sound of the op-amp

I mentioned the computer above because I'm sure these headphones would be even better with the appropriate system / amp

A good DAC and a strong amp really make the difference.

I've tossed them around inside my backpack and they are still in mint condition.-Buy a powerful amp

but all you need when paired with a decent amp

If you're willing to invest in bit more in a decent dac/amp; you'll be able to tap their true potential.

In conclusion these are comfortable, with good sound isolation and are easy to drive for inexpensive amps like the Samson S-amp

I used them for both recording and mixing for my amateur home music studio, as well as for general use (often late night music, TV, and movies).I was really pleased with the quality of these headphones

At first,​ I was worried about the headphone cable eventually breaking as it is not detachable, but from continuous use, I have seen no wear or tear on the cable itself.

I'm not too worried about them breaking as they are not flimsy like plastic beats and the like
