Wired headset or headphones.

Deliberately distinct from BLUETOOTH even though both are "headphones" to a user: a wired headset is driven off the same media path, and with the same timing, as the built-in SPEAKER. It carries no transport delay of its own, so it needs no extra latency compensation — the device's speaker-measured constant already covers it. Only BLUETOOTH adds a further remainder. Folding the two together would over-compensate every wired listener.
