Who it's for
The single-wire design keeps cable routing clean and low-profile, while the acoustic tube delivers audio quietly to your ear and the in-line PTT lets you transmit without reaching for the radio. That makes the PMLN7158 well suited to security, retail, and event teams running the SL300. To keep your radio powered on the floor, pair it with the Motorola 25009298001 Micro-USB rapid-rate plug-in charger for SL300.
