Description:Extendable Size:Adjustable to suits neck size between 12" and 15".Excellent Sound Quality:Dual-mic transponders designed on both the left and right side， sound is absorbed via vibrations from the throat and transferred to the radio which is then converted into recognizable voice frequencies. So， the throat microphone eliminates most background noise whether in the battle field or on the job site.Snug Fit Transparent Ear bud:The mushroom shaped acoustic tube earpiece is the best choice for long-hour operation. This throat mic is available in a professional grade acoustic ear coil. The proprietary， ergonomic design of the ear cushions ensures good fit over a wide range of ear sizes.Fine Transparent Acoustic Tube:You may hide the throat mic under the collar and the transparent tube earphone is not easily detected by the others. This is ideal for discreet communications.Analysis Of Experimental Tests:You may found cheaper throat mics (come with 1 mic on one of the sides) in the market， but sound quality will tell the difference. We have tested a number of similar products and this one is simply the best in transmitting voices in their authentic tones.Specification:Speaker Size: 12 mmMicrophone Size: 6.0 x 5.0mmSensitivity: 120 dB， +/-3dBFrequency Response: 20-16000 HzImpedance: 32 ohms， +/-15%Sensitivity: -37.56 dB， ¡À 2dBAudio Intput: 200mWImpedance: 2.20kW &1kHzResonance fre: 400Hz +/-20%S/N ratio: Min -56dB &1.1kHZNotice: Before Purchasing， Make sure it fits your transceiver.Applicable Model:TYT:TH-F2， TH-F3， TH-F5， TH-F6， TH-F7， TH-F8， TH-UVF8D， TH-UVF1， TH-UVF9/D etc.PUXING:PX-777/Plus， PX-666， PX-888/K， PX-328， PX-333， PX-999， PX-555 etc.QUANSHENG:TG-K4AT， TG-2AT， TG-45AT， TG-42AT， TG-22AT， TG-25AT， TG-UV2 etc.WOUXUN:KG-699， KG-689， KG-669， KG-679， KG-703， KG-659， KG-639， KG-833， KG-889， KG-869， KG-819， KG-816， KG-UVD1P， KG-UV6D KG-UVA1 etc.BAOFENG:UV5R/Plus， UV5RA/Plus， UV5RB， UV5RC， UV5RE/Plus， UV3R+Plus， UV-8/D， UV-82， UV-B5， UV-B6， UV-82， UV-8/D， GT-3 A52 etc.BF-388A， BF-K5， BF-A5， BF-480， BF-490， BF-320， BF-V6， BF-V8， BF-888s， BF-666s， BF-777s， BF-999， BF-888， BF-777， BF-658， BF-668， BF-530， BF-520， BF-658 etc.KENWOOD:Talk， Pro-Power Free-Talk， Protalk XLSTK-208， TK-220， TK-240， TK-240D， TK-248， TK-250， TK-270， TK-270G， TK-272， TK-272G， TK-278G， TK-308， TK-320， TK-340， TK-340D， TK-348， TK-350， TK-353， TK-360G， TK-360， TK-370， TK-370G， TK-372G， TK-372， TK-373G， TK-373， TK-378G， TK388G.Pro-Talk TK-2100， TK-2102， TK-2102L， TK-2107， TK-2118， TK-2160， TK-2170， TK-2170K， TK-2200， TK-2200L， ， TK-2200LP， TK-2202， TK-2202K， TK2212， TK-2212K， TK3100， TK-3101， TK-3102， TK-3107， TK-3130， TK3131， TK3160， TK3170， TK3170K， TK3173， TK-3200， TK-3200L， TK-3200LP， TK-3202， TK-3202K， TK-3202L， TK-3230， TK-3230XLS etc.TH-D7， TH-D7A， TH-D7AG， TH-D7E， TH-F6， TH-F6A， TH-F7， TH-F7E， TH-G71， TH-G71A， TH-G71E， TH-K2， TH-K2A， TH-K2AT， TH-K2E， TH-K2ET， TH-21， TH-21AT， TH-21BT， TH-22， TH-22A， TH-22AT， TH-22E， TH-25， TH-26， TH-27， TH-28， TH-31AT， TH-31BT， TH-41AT， TH-41BT， TH-42， TH-42A， TH-42AT， TH-42E， TH-45， TH-46， TH-47， TH-48， TH-55， TH-75， TH-77， TH-77A， TH-77E， TH-78， TH-78A， TH78-E， TH-79， TH-79A， TH-79E， TH-205， TH-205A， TH-205AT， TH-205E， TH-215， TH-215A， TH-225， TH-225A， TH-235， TH-235A， TH235E， TH-315， TH-315A， TH-415， TH-415A， TH-415E etc.Package Included:1 pcs Microphone Earpiece
