Tonal Profile
17 ohms and the most efficient driver Dan Clark has shipped in this price class. The first DCA headphone tuned to a revised Harman over-ear target, which matters more for what you hear than the 4 dB of sensitivity it gained.
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 | 17ohms | Sensitivity | ~94 dB/mW | Frequency response | Yes, it has one»
The sensitivity carries a tilde and no measurement conditions - no coupler, no measurement point, no tolerance - and the frequency-response row of the same specification table answers with a joke rather than a range. The number is usable as an order of magnitude, not as a figure to compare against a maker who states conditions.
