After going blind reading reviews of semi-portable closed phones to use with my new Pono player, I settled on the PM-3's (nowhere to audition anything decent in town). Unfortunately I won't be able to really audition them on my main rig versus the HD650's I have since the WA-2 is OTL and probably doesn't play well with the low impedance PM-3's. I was going to go for the HP50's, but I have a large hat size and was put off by the comments about comfort/fit on large heads. I'm also really curious about planars (considering PM-1's for the home system).

I have a big head/hat size and these fit my noggin the clamp force fells a bit strong but the overall comfort is really good.
