Howard Leight Impact Sport Features The Howard Leight Impact Sport earmuffs use digital sound compression to react in just half a millisecond instantly lowering harmful noise levels the moment a shot is fired. This near-instant response is what allows the earmuffs to provide genuine hearing protection with a 21 dB noise reduction rating while still letting the wearer hear quieter ambient sounds the rest of the time. Two high-gain omnidirectional microphones amplify low-level sounds by five times making range commands conversation and approaching game easier to detect. Recessed microphone placement also reduces wind noise which keeps the amplified audio clear even outdoors. Bluetooth 5.0 connectivity allows these earmuffs to pair with a mobile device for music streaming or hands-free phone calls adding convenience for long range sessions or hunts. Separate volume controls for Bluetooth audio and environmental amplification let the wearer balance both independently. The low-profile ear cup design uses Air Flow Control Technology to maintain a slim profile for firearm stock clearance while a padded adjustable headband ensures a comfortable custom fit. Included with a rechargeable lithium ion battery and USB charging cable these Gray earmuffs are a practical modern hearing protection solution for shooters and hunters alike.
