I recently purchased an SL2 and am happy with it for home use. Using the home kit, I get decent reception via the terrestrial signal. However, when I go on jogs, I get poor reception unless I wear the headphones it came with. I donâ€™t know what kind of long term health affects the headphone antenna have being so close to the brain, but I prefer to use my regular headphones. I just thought that the unit would get reception on its own when being outside. Do I have a bad device? Thanks.
