Read many reviews online about the Audeze iSine 20 and was very intrigued. Went to give it a trial a few weeks ago and compared it to Campfire Audio’s dynamic driver-BA hybrid Polaris; liked the Audeze better and bought it.
After a week or so, have finally become accustomed to the fit. I now find the iSine 20 physically rather unobtrusive. It produces a nice and natural soundstage, and while bass may not be thumpy heavy as my other headphones (ATH M50, Beyer T51p) it’s really excellent at jazz and spacey psychedelic / prog rock genres.
