About the KS 7.0

Update February, 2018: Kirkland Signature™ 8.0 hearing aids are now available.

Costco has not published detailed technical specifications on the Kirkland Signature™ 7.0 hearing aids. However, some have speculated that the KS7's might be similar in technology to the Rexton Trax 42 hearing aids, also sold at Costco. The KS7's look very similar to the Trax 42's on the exterior and are compatible with the same accessories (Smart Connect, Smart Power Charger, Smart Remote, Speech Connect) and smartphone apps (Smart Connect App and Smart Remote App). The Trax 42 hearing aids have 42 processing channels, 20 gain adjustment channels, 6 programs, directional microphones with mic-pattern adjustment, telecoil, Bluetooth wireless, rechargeability, etc. 

Informational videos, frequently asked questions, user guides, compatibility information, and more can be found at the Kirkland Signature™ 7.0 user portal. The current pricing for Costco's Kirkland Signature™ 7.0 hearing aids are $1,699.99 a pair.
