can anyone here compare these with the px5s pls,i was thinking about selling them

is there any good headphone that can work with ps3,pc, handphone(iphone or any other that use 3.5 jack )

the price ?
thinking of getting sony headset but cannot work with 3.5 handphone .

lol yea im slowpoke..but doesnt it need to use the 3.5jack hole to use it? nver use bluetooth headset before. but this headset wont work with iphone iinm?

but i still need 3.5 jack bcause my mp3 dont hve bluetooth. but i think its ok. can still use phone to hear songs

but if i buy another brand..will it be compatible?
bcause i got xperia play and nokia n82. the earphone only works with the original earphone. i tried plug in iphone 3.5jack to xperia play. it wont recognize.
as for nokia. the earphone only works with nokia products.

The problem with the PX21 is that it only fits for people with smaller ears (not saying yours are big, no offense bro!  ).
Otherwise yeah... it hurts because the auricle of your ear presses against the speakers itself and that hurts, after 2 hours of usage.

Sony headsest won't have such issues due to the much bigger allowance in the ear pads.
Personally, the only other gaming headset that feels more comfortable than the Sony is Steelseries Siberia v2.
