Stay protected and connected with our Restrictor BT Earbudsthe next evolution in sound enhancement and hearing protection technology. Designed for shooters, hunters and other outdoor enthusiasts, these premium earbuds combine an impressive 24 dB NRR (Noise Reduction Rating) to shield your hearing from gunshots and other loud noises, while integrating Bluetooth 5.0 for seamless connectivity through the Walker's Link app. With the app, users can independently control each earbud's volume, activate sleep modes, monitor battery life, and switch between four advanced sound modesUniversal, High Frequency, Power Boost, and Clear Voicefor an experience tailored to their environment at any given moment. This ensures wearers are prepared for shooting and other excessively loud scenarios by arming them with SAC (Sound Activated Compression) technology, which delivers crystal-clear digital hearing enhancement without compromising wearers' safety. Plus, everything about the appearance and functionality of the buds is streamlined and intuitive, from the patented Sure-Lock fin and foam tip system to the ergonomically placed buttons that are both easy to access and sleek in their appearance. And at the end of a long day at the range, the duo's built-in lithium batteries, which provide up to 14 hours' worth of runtime, are easily recharged using the included micro-USB cable, so you always have appropriate hearing coverage juiced up and ready.
