Just out of curiosity, why are you specifically looking for closed phones?
I use the AKG 271 mk2 primarily for tracking vocals and any other acoustic material where I want to avoid bleed from the phones to the mics. For most everything else and especially mixing, I use AKG K601 reference phones. These are open but bleed is not of concern here. They are lighter, very comfortable, and a great deal less fatiguing.
