Only the Hidizs AP80 Pro-X has a separate balanced rating from its maker; through it, it reaches 100 dB on 564 of the 567 models here. The TempoTec Variations V3 Blaze may still have a balanced socket — its spec sheet simply gives no figure for one, so there is nothing to put beside it. Derived figures are worked out from the loads the maker did publish.

Both makers publish a power rating. Hidizs AP80 Pro-X publishes at 32 Ω; TempoTec Variations V3 Blaze at 32 Ω. The other rows are worked out from those.
The two publish at the same loads, which is the one case where the rows of this table can be read straight across.
10 headphones reach 100 dB on the TempoTec Variations V3 Blaze but not on the Hidizs AP80 Pro-X — HiFiMAN Susvara, Moondrop COSMO, Moondrop PARA, 7 more.
556 of the 567 models here reach 100 dB on both.
Headroom is at a 100 dB SPL peak.
The widest gap on the list is the Audio-Technica ATH-R70X: TempoTec Variations V3 Blaze has +15 dB of headroom there against +5 dB. 11 dB is about 12 times the power, which matters for peaks rather than for how loud the music sits.
The hiss columns are empty for Hidizs AP80 Pro-X and TempoTec Variations V3 Blaze because neither maker publishes no output noise figure.

The Hidizs AP80 Pro-X costs $10 more than the TempoTec Variations V3 Blaze, and on these three axes the money buys nothing: among the 567 models here there is not one that the Hidizs AP80 Pro-X handles and the TempoTec Variations V3 Blaze does not — not on power, not on the one-eighth rule, not on hiss. The traffic runs the other way: the cheaper TempoTec Variations V3 Blaze drives 10 models to 100 dB that the Hidizs AP80 Pro-X does not.
Only published figures count here; blank axes are counted separately.
