Comfortable and capable - ISOtunes Sport DEFY BT Tactical Earmuffs with Bluetooth, 25 NRR

Used these for the first time at a very busy range last weekend. I was very pleased with how well the noise amplification works, while drowning out all of the shots and loud noises. I was there for 2 hours, and they stayed comfortable throughout. I've got a fairly large head, and the adjustments were abundant and worked perfectly to give me the comfort I needed while completely covering my ears. Not sure how good the battery life will be yet, but so far - I'm impressed and pleased with the quality and execution.
