I have been looking into headphones again and the Sundara might just be the ticket. The search began because my IEMs had been giving a mild case of tinnitus due to, oddly enough, the earplug pressure, not playback volume which has been safely around 50dB-70dB. Back when Tyll had first reviewed them, earlier revisions of the Sundara were plagued with quality control woes that left me reticent to committing to purchase. Fast forward to today, I just ordered a pair with one-day shipping so here's hoping these are groovy and good!
