Excellent headset - OTTO Engineering NoizeBarrier TAC

Very nice headset. Sound reproduction is spot on, at times seeming like you're not wearing hearing protection. Very easily dissembled without tools in order to attach to a helmet, and back again. Mic is removable and can be used on either right or left cup. They are fairly comfortable with memory foam ear seal. Minimal interference when shouldering a long gun. If you need a headset that you can attach to a helmet without cutting or breaking anything, then these may be what you're looking for.
