He likes to rotate between 3-5 pairs and usually leaves them throughout the house. But like I said I dont worry about loosing the phone as I ride. I use them inside industrial earmuffs for background track when drumming. I work from home and I wear slippers all day for support on the tile. This does not trap moisture and lets me workout with out worrying about scratches. Battery lasts about 5 hours of music, less when used for communication. Shortwave Freqs, SSB, FM, AM all perform strong on whip/ferrite. The jars are nice, though. Easy installation, took less than 5 minutes. Bought a warranty for it as well contact the place I got the warranty from and the seller of the speaker over a week ago and STILL havent heard back!
