This clinical investigation is designed to compare audiological performance (i.e., measurements of sound quality and speech understanding) between Starkey's new receiver-in-canal device and a commercially available legacy receiver-in-canal device.

Starkey is investigating a new hearing aid with several new audiological features. These features have been assessed for benefit, individually, but this clinical investigation will serve as a test for safety and efficacy with all hearing aid features, together. The design of this study is a single-blinded, crossover design and will be conducted at Starkey's headquarters in Eden Prairie, MN.

Inclusion Criteria:

• Adults, minimum age of 18

Exclusion Criteria:

• Inability to visit the Starkey Headquarters building for testing
