UPDATE @purrin measurements: https://www.superbestaudiofriends.o...2-measurements-and-thoughts.7194/#post-251075 Got a chance to measure my E2 with relatively good level of quietness. Honestly I was surprised again with their measured performance -- kinda had an assumption that mrspeakers don't measure good. (1/6 oct) (1/6 oct) All the measurements were done with the following setting: Minidsp EARS SBAF compensation curve: https://www.superbestaudiofriends.o...g-sbaf-compensations-from-minidsp-files.7067/ RME ADI-2 DAC Eddie Current Black Widow 2 Indeed, measuring E2's frequency responses is tricky for several reasons. I found that pad seal, headband fit, and "angle" affected measurements. Yes, angle matters. Non-circular shape of ear holes induce some variation on trebles, depending on the "angle" between ears and pads. This also mirrors my subjective experience -- finding an optimal position was critical to pull the maximum performance. For your reference, above results are based on the average among 5 pairs of measurements at different positions. Anyway, both objectively and subjectively, E2 sound quite neutral with a bit dark and warm top octaves. In particular, E2 has the best midrange quality among I experienced. Not overly meaty but full-bodied. Resolution is also very satisfying. While HD800 still wins in treble resolution, I could detect microdetails and microdynamics in bass and midrange more easily with ether 2 than hd800. But somehow suspect sins of commission -- reproduction seems too romantic for some tracks. Also with slightly exaggerated spatial cues. Overall, E2 sound very pleasing.. but I am not sure whether or not they reproduce "accurately". Compared to auteur (eikon pads), unlike the measurement suggests, I still think E2 is slightly brighter than auteur. Tonality is surprisingly similar. But to my ears, E2 have fuller bass and midrange, also outperform in transient speed and plankton. Auteur win in attack and macrodynamics though. It is worth noting that I felt my RME ADI-2 DAC was too polite when used with auteur and eikon pads, but with E2, everything sounds just right.
