Full disclosure, I own a pair of Drop's version, wich are supposed to be exactely the same, but then again only when they get measured here, with this set up, will we know for sure.
Amir's and others take on this phone puzzles me somewhat..To me if has always sound very full, with excellent bass extension, although not to the very end, say, from 40 downwards ( I hear no weakness up to on an electric bass lowest free string strum). That can be my ear canal or my auditory system on the whole (and I am talking nothing fancy amping them, laptops, and phones mostly) , but the thing is, this doesn't jive with the measurements, and perception of my own speakers vs these, for example. As I said, these phones always sound fuller, with more bass extension than my speakers, wich measured trough REW, show a better extension and some peaking on bass that has to be corrected with PEQ, and /FIR. Even when corrected to a +3-4 db shelf from 100 downwards the speakers sound noticeably leaner than fhe Senn's, but slightly lumpier on very low bass and clearly less clean, robust and effortless overall ( Kef reference 205 , amps are Hypex Fusions 503 in a 50 sqm room, )
I am nowhere near as knowledgeable as the majority here, but I remember reading how distortion ans harmonic profile alters subjective perception of sound and loudness.
Could that explain that difference in perception, and shoudn't that be taken in account when you calculate scores, if this is altering the actual perception, not the raw, individual measurements..? If a leaner measuring transducer in the bass actually sounds consistently fuller there is something not being taken in account its seems to me, but these are just my two cents..Overall, will never part with these, may get another ( Senn HD 800s maybe?) ..Not the pinnacle, not perfect, but 90 percent there, at a cost every music lover can eventually get one, a classic in the best sense.
