Dont get me wrong the Howard Leight Impact Sport are good muffs too and cost less than the Peltors but with my glasses I wasnt getting a full seal and the sound of gunfire slipping through the ear seals was getting annoying and I want to protect my hearing. Great accessory for drivers, very pleased with the headset. I love Bose, but the gauge of wire used for the internal connection (too thin or loosely soldered), or the planned obsolescence from Bose, is insufficient to last for anyone, that actually uses the headphones on a regular basis. Even just hoodies because it pops out by your pits. Paint rubbed off and biggie had no eyes. I went back and purchased the medium and they are perfect - not big at all. Aber die schwarze Sohle ist so hart, dass ich nicht damit laufen konnte und beim Anprobieren nur stolperte. Pull the top and back flaps away from the Velcro. This is my 3rd pair of Rowkin buds. These were just what I needed!
