Description: Features: 100% brand new and high quality. 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. 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. Finger PTT Switch: The finger PTT with a Velcro is enough for demanding outdoor operation. Notice: Before Purchasing, Make sure it fits your transceiver.
