Anyone Find Headphones To Be Uncomfortable

I just recently bought a pair of headphones to see what the fuss was all about. Unfortunately I find the listening experience to be uncomfortable with high levels of listening fatigue. Maybe it's the clamping force, the whole thing sticking to the head like a parasite. Perhaps it's the pressure that the cups impose upon the jawline, or the ears needing a breath of fresh air after being enclosed in a semi-tight chamber of some sort for long periods. Perhaps it's the sound pressure build-up within the open/semi-open/closed chamber. Or a combination of any of the above.

Initially I can't listen for more than 5 minutes but that improved to about an hour after some training. Nevertheless I still find the headphone listening experience to be uncomfortable(and unnatural) in comparison to loudspeaker-based systems.

Maybe I need more time to adapt to the headphone listening experience, or perhaps headphones just do not do it for me. I know this may sound ironic but sometimes music from the Edifier computer speakers (~$75) is more enjoyable than headphones (~$1000) despite people suggesting the other way round($1000 headphones offering more than speakers costing up to $2000). The discomfort and listening fatigue with headphones marred the listening experience for me. Does anyone feel the same with headphones?

For what it's worth, the headphone that I have right now is a Beyerdynamic T1. Are there any headphones that are substantially more comfortable than this with significantly lower levels of listening fatigue? Stax?

As a side note, I would like to clarify that my impressions above are not exactly a criticism toward high-quality headphones but more to my difficulty in adapting to them. There isn't any doubt that the Beyerdynamic T1 or any other good headphone designs are capable of a high quality playback and performance.

Any thoughts will be appreciated.
