The Kinera Loki Divine Mark is 14Ω. Its maker prints a sensitivity of 105.0 dB and never says whether that is per milliwatt or per volt, so this page reads it as per milliwatt — on that reading it needs 0.32 mW to reach 100 dB SPL, or 67 mV across the drivers. If the figure is really per volt, it needs far more.
That puts it in the easy category. A phone, a laptop headphone jack or the cheapest USB dongle will drive it to painful levels. Of the 280 sources in the database, 280 have at least 10 dB of headroom and another 0 have enough. The cheapest portable source that does the job is the Apple USB-C dongle (US) at $9.
This maker printed a decibel figure and no reference unit, so the number above is shown exactly as printed. Everything below reads it as per milliwatt, which is the commoner convention on a sheet that omits the unit — if it is really per volt, this headphone is about 19 dB harder to drive than the rest of this page assumes. The converter explains the difference.
Kinera publishes a sensitivity of 105 dB and does not state whether that is per milliwatt or per volt — the spec sheet simply stops at the number.
Both readings are given here so you can judge for yourself. If that 105 dB is per milliwatt, the figures on this page are right as they stand. If it is per volt, the real sensitivity is 86.5 dB/mW — 19 dB lower at 14Ω — and everything above understates what these need by that much. The per-milliwatt reading is the one shown, because it is the more common convention on a spec sheet that omits the unit; treat it as an indication rather than a specification.

| As it is labelled | As printed | Tolerance | Standard |
|---|---|---|---|
| Frequency Response | 20Hz - 50kHz ultra-wideband | not printed | not printed |
Kinera prints 20Hz - 50kHz ultra-wideband for the Kinera Loki Divine Mark, under the heading “Frequency Response”. Source: kineraaudio.com.
Kinera prints “ultra-wideband” inside the specification cell, next to the numbers and in place of the tolerance that would have said what the range means.
No tolerance is printed with it, so “20Hz - 50kHz ultra-wideband” says nothing about how loud this headphone actually is at 20 Hz.
Only what the maker printed; maker by maker.
| Level | What it is | Power | Voltage | Current |
|---|---|---|---|---|
| 85 dB SPL | quiet background listening | 0.01 mW | 12 mV | 0.8 mA |
| 95 dB SPL | normal listening | 0.10 mW | 37 mV | 2.7 mA |
| 100 dB SPL | loud listening | 0.32 mW | 67 mV | 4.8 mA |
| 105 dB SPL | very loud | 1.0 mW | 0.12 V | 8.5 mA |
| 110 dB SPL | peaks on dynamic music | 3.2 mW | 0.21 V | 15.0 mA |
Most people listen between 75 and 85 dB; the 100 dB row leaves room for peaks.

Hiss. At 123.5 dB/V these are sensitive enough to reveal a source's own noise floor. The noisiest source in the database, the Schiit Mjolnir 3, would put its hiss at roughly 32 dB SPL in these headphones — clearly audible in quiet passages. Check your own source.
Output impedance. At 14Ω these want a source output impedance below 1.75Ω to satisfy the one-eighth rule; 40 of the 192 sources that publish one miss it. Check yours here.
