With high-quality source material and a decent amp, you will be astounded at how good these headphones can sound

It gets richer and full with an amplifier, but it doesn't take much, a wee portable or basic desktop amp will do it

I'd imaging you'd be able to fir extra wires, adapters, your mp3 player, and a portable headphone amp

You really need a good headphone amp for use with these headphones to get the full dynamic range from them.

but I would still recommend an amp.

Sound stage is very nice would definitly recommend an amp to get full sound quality because ipod and laptop are not enough.

While the Pro 750 don't require a headphone amp to run, I would recommend a good quality amp like the Fiio E11 if you are going mobile with an iPod or smartphone being your music player

There's a guy that sells some nice burr-brown portable amps from his ebay store that are inexpensive and work well with these cans

With a weak amp or connected to electronics with unemphasized bass (like most pro audio gear), it is acceptable, but not with many consumer audiophile electronics with boosted bass themselves

You can really crank them up with a good amp and they sound great never harsh or grainy

I've used these at home with a good amp and on bussiness trips, I don't think they were made for everyday commuting?

They CAN run from a computer or phone, but the difference with a proper amp is remarkable; everything comes to life

With some proper amp/dac and good quality songs, this headphone will redefine music itself

I listen to mostly trap, and some other types of EDM and with a proper amp, these things really come to life

An amp is recommended to get the true soundstage from these bad boys but they still work without one

Good analytical detail and good soundstage regardless of source and amp thanks to high efficiency drivers, and excels at ambient detail/echo in proportion to better source and amp

I loved my Beats as it's super comfortable on my ears, noise isolation despite not being advertised for it, and the sound signature

Over time as they've gotten burned in, they have lost that edge a bit
