Stone Mountain Phoenix Remote Speaker Microphone with Channel Selector - XP5s and XP8

Stone Mountain Limited (SML) Phoenix Remote Speaker Microphone (RSM) is the only RSM for PTT over cellular with a 10 channel selector and one touch high and low volume controls. SML custom designed the Phoenix RSM to reliably connect to Sonim's SecureAudio Connector on the XP5s and XP8 handsets. This allows the Phoenix RSM connector to screw into the handsets and draw power. Phoenix RSM is ultra-rugged, passing MIL-STD-810G for vibrations and shocks and IP-68, making it resistant to micro particles and water submergible.
