Replacement charger case for the Kirkland Signature 10.0T (Telecoil) rechargeable hearing aids. This plug-in hard-shell charging case fully recharges the KS 10.0T hearing aids in approximately 3 hours, or to 80% capacity in about 1.5 hours. The charger case is designed for the receiver-in-canal (RIC) style KS 10.0 hearing aids with built-in telecoil, which connect to iPhone and Android smartphones via Bluetooth. The "T" designation indicates the telecoil-equipped variant, which includes a small coil of wire within the hearing aid that enables clearer phone calls and compatibility with hearing loop broadcast audio systems.
