I tested the HiFiMan Arya's briefly, the first thing I noticed is that they are brighter than the Sundara, though I think that is mostly because I swapped the Sundara pads for suede ZMF Auteurs. Soundstage is also noticeably wider.
Comfort out of the box is excellent, loads of room for my ears and they don't get close to touching the drivers. Clamping force feels just right and as it's spread over a larger area with the huge earcups you feel less pressure. In contrast the Sundara was very poor out of the box, too much clamping force and the stock pads were too small and shallow so I had to pad swap and bend the metal headband.
The only negative is that the mesh material on the pads isn't very nice, but it might get softer as they wear in. I'll probably upgrade them if I find something better that doesn't change the sound much.
