Hearing protection.

I shoot a lot and have tinnitus from helicopters, explosions, and shooting. I am cheap and just use foamies when I shoot or run a chainsaw now. I have been wanting to get some ear muffs for shooting that have bluetooth but I don't really want to listen to music when I shoot or saw. Plus, it is a short duration that I would use it anyway. I shoot, take them off, and go check my targets. Seems like a waste for me but for someone who spends more than a song's duration of time I could see the cost being worth it.

Walker's is a brand I see a lot in the shooting sports arena. I would check their products out. Also, if you go on MidwayUSA.com or another shooting sports retailer like Bass Pro or Brownells you will be able to find a cheaper off-brand to the Walkers ear muffs.
