Hear everything, only quieter.
The problem with virtually all ear plugs is the way they distort and muffle sound. This not only makes it difficult to have a conversation, but makes built-in helmet speakers sound like crap. By miniaturizing the acoustic filters found in $180+ professional musicians ear plugs, we have been able to make an affordable filtered plug that can be comfortably worn under a helmet all day long. With 20dB noise reduction, the Filtered S Plug works great as every day hearing protection on and off the bike, and lets helmet speakers sound their best. Proudly made in the USA.
