Expert Audio Engineering Commentary

Tonal Profile

A 7 mm TrueResponse dynamic — the same transducer family as the IE 600 and IE 900. The supplied tips have two positions on the nozzle; the deeper one adds bass, and Sennheiser treats it as a tuning control rather than a fit option.

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.

Measurement conditions
«Impedance (without cable / with cable) 16 Ohm / 18 Ohm»

Almost no manufacturer separates these two, and Sennheiser is right to: the source is connected to the cable, not to the transducer, so 18 Ω is the load that matters and 16 Ω is a property of the driver alone. The two ohms of difference are the cable's series resistance. We store 18 Ω. The reason to record the claim is the opposite case — when another brand prints a single low number, you now have no way to tell which of the two it is, and the difference lands exactly where low-impedance in-ears are already sensitive to source output impedance.
