I felt horrible after that whole thing, thats why the caveat obviously...these have the polished and dynamic low end the ety's never had. It was the only thing my MC5's were lacking, they (mc5s) were that very first b-stock purchase i made at headroom by the way. If the etys had any low end I'd still use them daily.
The Senns have the perfect amount of highs,lows and mids to my ears. I enjoy good low end done correctly and to me these have that. I've spent a lengthy amount of time today using the Senns within a wireless or bluetooth setup I've recently started watching films with all to try and make any worts appear anywhere...so far so good.....best to try first in any event to avoid any mixups....I'll update this if they change dramatically....over time....
