U-94 — Kenwood 2-Pin (K1)
Mil-spec U-94 push-to-talk for Kenwood K1 2-pin radios and K1-compatible handhelds (Baofeng, Wouxun, Retevis, and more).
U-174 Headset
Radio Interface: Kenwood 2-Pin (K1)
Connector: K1 — 2.5 mm / 3.5 mm dual-prong
Verify your radio connector visually before ordering. Headset side is standard NATO U-174/U (TP-101). U-384/U (TP-105 / red rings) needs the TP-105 O-Ring adapter.
K1 is the standard commercial 2-pin. If your Kenwood has a multi-pin side connector (NX-5000 / X11 family), you need the K2 / X11 U-94 — not this K1.
