Band: opinion spread · Dot: weighted average
Sources split, though not evenly. Most call the low end the headphone's strongest suit — deep, physical and unusually well controlled for a closed-back, with the emphasis kept in the sub-bass so it never bleeds upward. A minority hears the opposite: bass that is light for a closed-back, or a hollowed-out step between the bass and the mids. The measurements back both: the sub-bass shelf is no bigger than a FiiO FT1's, but a 150 Hz tuck 3–6 dB below the FT1, 109 PRO and Liric 2 is what the second camp is hearing as missing punch. Seal matters more than usual (the vent is doing real work), and two owner 'no bass' threads turned out to be the 3.5 mm plugs not pushed in to the click.
Measured
B&K 5128 (Earphones Archive, five seatings): +6.1 dB at 20 Hz re 500 Hz on every seating (sd 0.3), then −2.1 dB at 150 Hz. Same rig: 1.8 dB less sub-bass than a FiiO FT1 and 5.4 dB less at 150 Hz; 0.5 dB more than a Focal Azurys at 20 Hz, 3.1 dB less at 150 Hz. GadgetryTech's rig: 6.5 dB more than the 109 Pro at 20 Hz, 3.2 dB less at 150 Hz.
vs. listeners — The graph supports both camps: the sub-bass extension the majority praises is real, and so is the 150 Hz tuck the minority hears as thin punch. The 'no bass at all' owner reports are fit or cable seating, not the tuning.
“The bass response is arguably one of the Strada’s strongest assets.”
Animagus, Twister6
“The one flaw of the bass response is that it dips a bit towards the upper end of the bass/the transition to the midrange in a way that can make some things feel a bit hollowed out.”
