The Kirkland Signature 10.0 Custom Color hearing aids are premium receiver-in-canal (RIC) style digital hearing instruments sold at Costco Hearing Aid Centers, available in a choice of custom colors to match personal style. Manufactured by Sonova — the company behind the Phonak brand — these hearing aids deliver performance comparable to premium name-brand devices at a fraction of the cost, priced at $1,399 per pair including the charging case.

The hearing aids feature lithium-ion rechargeable batteries with a included plug-in hard-shell charging case. A full charge is achieved in approximately 3 hours, with 80% capacity reached in just 1.5 hours. Bluetooth connectivity enables direct audio streaming from smartphones and other Bluetooth-compatible devices, with simultaneous connections to two devices supported. Hands-free phone calling is built in, and a double-tap gesture on the hearing aid answers calls, pauses or resumes streaming, or activates your smartphone's voice assistant.

A built-in telecoil (T-coil) provides compatibility with hearing loop systems found in theaters, houses of worship, and other public venues. Smart technology automatically adjusts settings across 9 automatic programs as listening environments change, while 20 fine-tuning channels and 4 manual programs allow precise customization. Additional capabilities include Echo Manager, Speech Boost, a built-in accelerometer for improved speech understanding during movement, and a dedicated tinnitus relief feature.

The KS 10.0 carries an IP68 rating for water and dust resistance, surviving immersion in 1 meter of water for 60 minutes. Compatible accessories include the TV Connector, PartnerMic, Roger system, Easy Line Power Pack portable charger, and Remote Control. Volume, programs, and audio stream mix can be adjusted through the Easy Line Remote smartphone app. The set includes the pair of hearing aids, charging case, cleaning brush, and cleaning cloth.
