Headphone Output Power into 16 Ohms (Unbalanced)
This rating states continuous power per channel from the single-ended headphone output into a 16-ohm load.
It is expressed in milliwatts or watts. Low-impedance loads can demand substantial current, and headphone sensitivity is also needed to relate electrical power to listening level.
Headphone Output Power into 16 Ohms (Unbalanced) — Headphone Amp
The 16-ohm figure describes the amplifier's output under that specific load. It helps assess available headroom for low-impedance headphones, provided the distortion limit and other conditions are retained. Higher permitted distortion can yield a larger published power number without representing the same operating point.
Compare continuous per-channel ratings at 16 ohms from the single-ended socket, with matching gain, operating mode and channels-driven conditions where stated. Do not add the two channel powers or substitute a balanced-output figure. A rating at 32 or 300 ohms, a peak-power claim and a maximum voltage alone are different measurements.
Headphone Output Power into 16 Ohms (Unbalanced) — Digital Audio Player
For a player, this describes the supplied amplifier module's single-ended output into 16 ohms. The main figure prioritizes the highest stated battery-powered result; a separate desktop or DC-powered result needs its own qualification. External power can enable a mode that is unavailable while listening from the battery.
Compare the same power source, socket, gain and distortion limit. When only an externally powered rating is available, keep that fact visible; an unspecified supply remains unspecified. A larger balanced-output rating does not describe the single-ended socket. Sensitivity still matters: impedance and electrical power alone do not determine the achievable acoustic level.
