YakaI'll let you know when I get mine. I've had over 15 sets of earplugs for riding motorcycles and keep trying to get better ones. I use in ear monitors now, but will try these with helmet mounted speakers.
YakaI use the blue 21 dB in my convertible on the highway. Just right for me. No wind noise. Takes volume down about 25% based on how much I need to turn up radio volume. Very clear and uniform noise reduction across the spectrum. Sound around me is mostly natural and never unsafe/uncomfortable. I used to ride and personally would go 25 dB for the motorcycle.
