i plug into my smart phone(lg g3) is amp needed for the volume only or does it make a difference to the sound hd600 produce?

Anybody got any ideas..?

I tried listening to both devices yesterday. this is the impression i got: - 1440 has brighter sound compared to hd600 - hd600 sounded more lively when listening to piano songs i couldnt hear the very details cuz it was a lil noisy in the shop. so overall, i got better impression with srh1440...

do you think srh840 has quality bass? i tried it and it definetely doesnt have a lot. i think it has a sufficient amount

Alright thx for your thoughts. if any of you have any more comments please leave it here :) i'd like to hear few more

so do you think beats has quantity only or quality and quantity? in my opinion beats has quantity whereas srh840 has quality

so if you are not a super-bass heavy person srh840 is better? if you compare high,mid,bass, sound stage which headphones sounds better in each case?

Hi guys i would like to ask your opinion on which headphone is better. please dont consider the price or price/quality ratio and simply compare the sound quality. assume that you have all the money you need. So which headphone would be a better choice only considering the sound...
