Retevis earpiece with mic for RT20 walkie talkies uses a 2.5mm 1-pin plug with inline PTT and microphone. The C-shape hook fits left or right ear, with a clip to fix the 120 cm cable to clothing.
Built for security, restaurants, warehouses, events and paintball crews, it provides clear audio without a speaker blasting. Works only with Retevis RT20 and other listed 1-pin 2.5mm models such as DEWALT DXFRS800 series and Gaswei G2pro.
