Both are portable players, $189 against $179. This page puts them side by side on the only three things a maker can be held to — power, output impedance and noise — and then asks the question that actually matters: which headphones do they treat differently?
The TempoTec Variations V3 Blaze reaches 100 dB on 566 of the 567 models here, the Hidizs AP80 Pro-X on 556.
| Specification | Hidizs AP80 Pro-X | TempoTec Variations V3 Blaze |

| Power into 150Ω | 15 mW | 176 mW |
| Power into 300Ω | 7.5 mW | 88 mW |
| Power into 600Ω | 3.7 mW | 44 mW |
| Output impedance | not published | not published |
| Output noise | not published | not published |
| Price | $189 | $179 |
| Headphones it reaches 100 dB on out of 567 | 556 | 566 |
A figure marked not published is missing from the maker’s own material, which is not the same as being good or bad. Where one of these two publishes a number and the other does not, the comparison on that axis cannot be made at all — and saying so is more useful than guessing.
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. That is a power count and nothing more; whether either source suits a given headphone also depends on the two lines above.
Each has a page of its own with every power figure traced to what the maker published and a full headphone list: Hidizs AP80 Pro-X and TempoTec Variations V3 Blaze. Or put either against your own headphones in the source comparison tool.
