Feature: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.Specification:Condition: 100% Brand NewItem Type: Throat MicColor: as picture shown2 pin standard diameter: ear plug 2.5mm stereo (thimble), microphone 3.5mm stereo (bottom pin).2 pin space: 8mmCompatible for Motorola portable two way radios model: for XTN Series:XTN446, XTN500, XTN600for XTN XV Series:XV1100, XV2100, XV2600, XV4100for XTN XU Series:XU1100, XU2100, XU2600, XU4100for XTN AX Series:AXV5100, AXU4100for CLS Series:CLS1110, CLS1410, CLS1413, CLS1450, CLS1450C, CLS1450CB, VL50for Motorola Spirit Series:SV10, SV11, SV11D, SV21, SV12, SV22, SV22C, SU210, SU22, SU22C, SU220 VHF / UHF Spirit, Spirit Pro, Spirit Pro+, Spirit HP 10for Spirit MU Series:MU11, MU11C, MU11CV, MU12, MU12C, MU12CV, MU21C, MU21CV, MU22CVS, MU24CV, MU24CVS, MU24CVSTfor Spirit MV Series:MV11, MV11C, MV11CV, MV12, MV12CV, MV21C, MV21CV, MV22, MV22CV, MV24CVSfor CP Series:CP88, CP040.
