GSM Silencer BT 2.0 Features The GSM Silencer BT 2.0 Electronic Ear Buds use Bluetooth 5.0 to stream audio and take calls while still protecting hearing on the range and the newer Bluetooth standard brings improved battery life and a wider more stable connection range than earlier versions. Sound Activated Compression continuously monitors ambient noise and clamps down the instant it detects a loud impulse like a gunshot then returns to normal passthrough so the shooter can hear range commands and conversation without interruption. Touch button controls keep adjustments simple without fumbling for tiny physical buttons while wearing gloves or ear protection and voice prompts confirm settings changes so the shooter always knows the buds current mode. An auto shut off feature conserves battery power when the buds are not in use extending the Li-ion battery s rated run time of up to 14 hours between charges. Built in an In The Ear style sized for adult use the Silencer BT 2.0 is finished in a white polymer exclusive to this edition. The included USB charging dock with its integrated rechargeable lithium battery allows the buds to recharge on the go without a wall outlet which is useful for all day range sessions or hunting trips far from power. Three sizes of Sure-Lock fins and foam tips in small medium and large let each shooter dial in a secure comfortable seal for consistent hearing protection and audio quality. A cleaning brush and Micro USB cable round out the included accessories giving the GSM Silencer BT 2.0 everything needed to maintain and recharge the buds for the long term.
