[stymie miasma]

I am looking for comments/impressions/comparrisons of the sound quality of these two portable headphones. I realise the PX-100 is open while the PX-200 is closed - would it be correct to assume that the same drivers are used in both? I will be using these for portable use without an amp - straight out of my Sharp MDMT99. Isolation is not really a huge issue for me.

Assuming the sound quality is comparable, I am leaning towards the PX-100 purely for comfort reasons. The pleather earpads on the PX-200 don't look too appealing.

Thanks in advance
