I just purchased a pair of 3 year warranty ear plugs. At BMW MOA Das Rally. On my first ride 10 hours back to Virginia on Sunday. I loved them. I have tried all kinds of foam and rubber ear plugs. None are comfortable after 2 hours or come close to the hearing protection. The crowd at your booth versus the other ear plug booths speaks volumes. I can’t wait till the Washington D.C. Progressive Motorcycle Show in January to get a spare pair.
