Based on suggestions here, I just tried the V-Moda M80 and I did not like them at all, especially compared to the Momentum On Ear. I also just bought the Momentum full - again - and I love the sound, definitely a step up above the On Ear, but I'm grappling with the discomfort. The pads are super soft, but they don't place well on my ears. I take them off after an hour and it's such a relief! I tried Bose again as recently as last year. I had previously owned the first two generations of the QC headphones. I never enjoyed them for classical. I prefer the HD598 for classical. I'm leaning towards the Momentum On Ear for portables including walking around the house and watching movies with my Sony goggles, and the HD598 for home relaxing in my Lazboy. Except for classical, I think I prefer the Momentum full over the HD598. Maybe I just need to find a larger more comfortable close pair for non-classical music.
