I have the 3M Peltor ear buds and like them. I now have two sets; one set of their tactical TEP-100s and one of the industrial EEP-100s. Both have a cutoff at 80 dB, which was slightly lower than most of the "sport" ones I saw, and are USB rechargeable, with cases that act as chargers. Noise reduction is good even with the flanged ear tips (23dB), but they offer other tips that offer greater reductions. They stay in my ears all day comfortably.
Both models are functionally identical, but the EEP-100s are bright green, have a smaller case, and don't come with the little lanyard that connects them. The TEP-100s are black, with a bigger case that can use 3 AA batteries to charge the ear buds if USB isn't available, and come with the lanyard and some foam wind blockers to put over the microphone.
Both models charge quickly and seem to last all day, and even without the wind blockers I haven't noticed much wind noise, even here in the Snake River plain, even with the sound amplification turned up.
