Ive used the Howard Leight Impact Sport and the Peltor Sport Tactical 100 and Im liking the Peltors way more because of the ear seals on the Peltors. Very light weight just what I wanted An incredibly annoying feature is the low battery alert, which kicks in when levels hit 30% - it gives a loud beep at 1 minute intervals. I workout often and since the gym has closed Ive been resorting to running outside as much as possible. My boys are very hard on them half the time when there not on there head they are on the floor very well made and very durable! Touch sensitivity to control player/phone seems very good too - may be even too good - even slightest tap controls the connected device. Im still trying to get the memory foam broken in but otherwise they are perfect! La talla viene muy amplia I too had to be equally generous and therefore sought neither the refund nor returned the device. I wish more shoes could be bought with the memory foam insoles, as they left me feeling that I could happily walk all day in them.
