Dunnersfella: sleemanj - have you considered that the content you're listening to is of poor quality / your hearing is damaged?
I listened to some $1500 h/phones today through a headphone amp... and there is no way, on this earth, that you could compare the sound coming out of a pair of Philips $12 headphones.
No way.
Ever.
I mean, ever.
Life is too short to listen to crap sound... and I don't spend much on headphones as I rarely use them.
I totally agree. I have never heard a sub-$200 set of headphones that I would be happy with and you need to spend a lot more than that if you want noise cancelling.
Personally I'm a big fan of Sennheiser because they're the only headphones that I've managed to make last for years rather than months, and I like how their sound profile gives good clear reproduction of vocals and stringed instruments, where Japanese headphones have a nasty tendency to drown out everything with boomy and overbearing bass. At the moment I'm using the PXC-250 which I've had for 2.5 years, but I understand that the newer PXC-250-II is even better.
