The second ones down. 33 NRR


For $0.96, 5 pair, and come with a small tube to keep a pair clean. Handy to have in a coat or jacket pocket (or tank bag).

I can hear the sound of the engine (intake/exhaust), enough sound from other traffic, etc., but it cuts out the wind noise. If I'm riding for more than 20 minutes at highway speeds, I'm wearing them.
