Do these subjectively good-sounding headphones measure well, too? Let's find out. Above is FR plot compensated against older SBAF curve which I consistently use for all my measurements. 1/24 oct smoothed. My favorite pads (Geekria L) were equipped. Mild imbalances were seen in the graph, but nothing looks critical to me. The overall tonal balance seems shaped like V centering at 900hz. That's largely consistent with what I heard. Bass starts to roll off at 60hz, but please note that in reality this hugely depends on how earpads are fitted with ears (real/dummy). This implies while the result above wasn't too different from my perception, you may hear a little deeper or shallower basses based on how the Mini seals your ears. Between 4khz and 5.5khz, energy level looks higher than the surrounding regions. Also a little zigzagging to my eyes. Subjectively my ears didn't find it rough at all, but some pads helped to smooth out it measurably. More on this below. Big scoop around 7-10k seems more drastic than what I perceived. Pre-post comparative plots above. Solid line means pre-EQ response and dotted one corresponds to post-EQ. My filters largely "weaken" V-ness by dropping some bits in whole bass and upper treble. Post EQ, midrange level is more in line with bass and treble energies. Differences across three pads I tested. Best orientation for each was displayed (backward for Geekria L and forward for the rest). For visual convenience, I zoomed in a little bit in y-axis. Gerod L (green) does smooth out treble response between 3khz and 6khz. I doubt if I can hear it as much as the graph suggests though. Geekria L (red) seems the most neutral among the bunch. Measured differences were narrower than I heard/thought. I surmise that maybe different physical texture or wearing experience served as some confounders in my perception. More to come in the next post..
