Looking for a comfortable portable headphone

[monster7]

Hello, I would like to seek for your advice on portable headphone. I will use it when I play poker in casino, I prefer open ended as I dont want noise isolation. I will drive them by Oppo HA-2. I have tried the following closed ended
 
Sony MDR 7506: light and comfort, but very harsh treble, I cannot stand it

Grado SR80i: warm vocal and guitar, but no sound stage, bass is too weak

Shure 440/840: very detailed, sound stage is good for a closed can, vocal is good too, bass is a bit blurred, but it is too bulky.

UE 4000: light, the sound is good in general

AKG 451: kinda light-weighted sound, good for acoustic music, but bass is too light 

Skullcandy Aviator: Bad sound for the price

PSB M4U 2: bulky but sound very good

ATH M50x: sound good but uncomfortable

V-moda xs: sound good but uncomfortable

For open ended

Senn px100-ii: warm and laid back sound, but quite muddy, very comfortable

Koss pp: Bass is too strong, surprisingly quite comfortable for me

Shure 144: not good sound compare to the aboves

So my question is, is there any HP as comfort as px100/ Koss pp, but sound quality is better? Some closed can sound really bad like I am standing outside of a disco room to listen music.

Cheers  bros.

Sennheiser PX95, I don't have the PX100 anymore but I think the PX95 may clamp a bit tighter on the ears.
 
Koss KSC75 with Parts Express headband, these are the most comfortable on-ear headphones I've used, also less bass than Porta Pro so they may be suitable for you.
 
V-Jays is another option.  Out of the box they clamp quite tight, but they loosen up after a while.
