Headroom Notes
A six-gram cable adapter rated up to 70 mW + 70 mW into 32 ohms, which is 1.5 V — about the same as a good phone jack used to be, and roughly a quarter of the voltage of the desktop units in this batch. That is the honest ceiling of the category, and Hidizs states the 32-ohm test condition rather than leaving it out.
