Out of curiosity, why did you return the T5? From your posts, I gather that it was mostly an issue of comfort? My auditions with the Beyerdynamic have not yielded any complaints in the way of comfort (or the lack of); however, I suppose long-term use may reveal a niggling issue or 2.
In any case, my most-recent go with the T5 was just last Friday. I actually expected to leave the store with a brand-spanking new Beyer; I departed with a Focal Celestee instead. Now, I'm not bashing on the T5 (3rd Gen) - it has a unique signature that's not often replicated in the higher-tiers of the headphone world. It is an acquired taste, but if you're in the market for potent bass, gobs of warmth, silky-smooth sound, and a darker tone, there are few contemporaries in the market. At least, few that share the same character, and are yet technically competent enough as to warrant that coveted
"High-End" tag.
Some day, I might just get my hands on a T5 (3rd Generation).
