Tonal Profile
24 ohms, 105 dB/mW: the easiest headphone in this batch to drive, and the only Denon over-ear whose page still publishes electrical data at all - the AH-D7200 page, same 50 mm FreeEdge driver and same series, lists neither impedance nor sensitivity.
What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
«Impedance 24ohm | Sensitivity 105dB/mW | Maximum Power input 1.800mW | Frequency response 5-56.000Hz»
The en-US page writes its large numbers with a full stop as the thousands separator: '1.800mW' means 1800 mW and '5-56.000Hz' means 5 Hz to 56 000 Hz. Read with the decimal convention that page's own locale implies, the power rating becomes 1.8 mW - a thousand times smaller. The figure is quoted here verbatim rather than carried into a field.
