Review on Ultimate Noise Isolating Earplugs: Plugfones Guardian Plus - Enhanced Audio, 26 dB NRR, Mic & Controls by Sharon Weston

Works as expected. I wear them when riding my motorcycle. True, at high speeds the music is not very easy to hear. It's better than skull lozenges which don't block as much noise and stay in my ears like headphones do when wearing a helmet on a bike. The sound quality is mediocre, but perfectly acceptable for an iPhone with small speakers. The buttons on the controller are not so easy to press when wearing gloves. I would like to have the left and right indicators on the headphones.
