Product
EarJack™ is designed to help rinse away earwax buildup at home with controlled water flow.
Always begin with the lowest mode and only increase if it feels comfortable.
Use lukewarm water for a more comfortable experience.
Use it only as needed. Many people only reach for ear-cleaning support when buildup becomes noticeable.
EarJack™ is designed as a more controlled water-based alternative for earwax buildup, instead of inserting cotton swabs into the ear canal.
Do not use it if you have a perforated eardrum, ear tubes, an active infection, strong pain, or after ear surgery unless your doctor says it is appropriate.
Yes — EarJack™ charges via USB-C for convenient cordless use.
