Features 1.Remote microphones with button calls can be used anywhere. 2.The microphone is transmitted directly from the throat and is therefore insensitive to background noise. 3.It is difficult for those around you to find the best quality transparent tubes and protect your health from the effects of radio radiation. 4.This is very suitable for high ambient conditions such as driving, riding motorcycles and bicycles. 5.It is also well suited for crowd control at airports, casinos, public places and concerts and for surveillance purposes and security in other work environments that require careful communication. The throat microphone is also easy to hide under the collar. specificationCondition: 100% Brand New Item Type: Throat Mic Color: as picture shown 2 pin standard diameter: ear plug 2.5mm stereo (thimble), microphone 3.5mm stereo (bottom pin). 2 pin space: 8mm Compatible for Motorola portable two way radios model: for XTN Series:XTN446, XTN500, XTN600 for XTN XV Series:XV1100, XV2100, XV2600, XV4100 for XTN XU Series:XU1100, XU2100, XU2600, XU4100 for XTN AX Series:AXV5100, AXU4100 for CLS Series:CLS1110, CLS1410, CLS1413, CLS1450, CLS1450C, CLS1450CB, VL50 for Motorola Spirit Series:SV10, SV11, SV11D, SV21, SV12, SV22, SV22C, SU210, SU22, SU22C, SU220 VHF / UHF Spirit, Spirit Pro, Spirit Pro+, Spirit HP 10 for Spirit MU Series:MU11, MU11C, MU11CV, MU12, MU12C, MU12CV, MU21C, MU21CV, MU22CVS, MU24CV, MU24CVS, MU24CVST for Spirit MV Series:MV11, MV11C, MV11CV, MV12, MV12CV, MV21C, MV21CV, MV22, MV22CV, MV24CVS for CP Series:CP88, CP040.
