●Easier and more comfortable to use: with smaller earplugs which are worn hanging around your ears, it will comfortably fit even to a small ear.
●The set comes with a sound collector for good pickup of sound.
●The sound collector is easy to use with the power and volume switches in one. Sound volume is adjustable for the high-pitched and low-pitched sound separately. (Please note that if the volume of the low pitch is raised excessively, it will increase the vibration of the earplugs)
●Clip and neck strap of the sound collector give added comfort for outdoor use.
