Can PSP Headphones Work on Nintendo Switch Lite? Compatibility Guide

Yes, standard PSP headphones work on the Nintendo Switch Lite. Here's the detailed breakdown.

Port Specifications

Device	Audio Port
PSP (1000/2000/3000/Go)	3.5 mm TRS (Stereo) — PSP-1000 also has a separate remote port
Switch Lite	3.5 mm TRRS (Headset with mic support) + USB-C (Digital audio)

Compatibility Results

Standard 3-pole (TRS) headphones: Work perfectly for stereo audio output.
4-pole (TRRS) headsets with microphone: Work for both game audio and voice chat.
PSP wired headsets (with mic): Use TRRS connectors, so they function fully on Switch Lite for audio and microphone.

Caveats

Inline volume controls on the headset cable may not function (different signaling standards).
The PSP-1000's proprietary remote control accessory will not work.
USB-C headphones or USB-C-to-3.5mm adapters also work on Switch Lite.

Verdict: Plug your standard 3.5mm headphones or headsets (including PSP models) directly into the Switch Lite's headphone jack. Audio works immediately; microphone works if the plug is TRRS (4-pole).
