Moisture build-up from sweat and body oils can ruin the performance of IEMs. The Dry & Store Zephyr by Ear Technology is an electronic desiccant (drying) system which, when used consistently, can virtually eliminate the expense and aggravation of moisture-related IEM failure.
The Zephyr is an AC-powered system with high-efficiency non-renewable Dry-Brik II desiccant. Just drop your earphones into the drying compartment, snap the lid shut, and turn it on to gently evaporate and expel moisture from your earphones over its 8-hour duty cycle. Dry-Brik II desiccant is so powerful, it also acts as a deodorant. A single brick is good for two months; replacements are readily available direct from Sensaphonics.
