The Jabra Enhance Pro 20 at Costco is a prescription behind-the-ear hearing aid available for $1,600, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This places it in the top 61% of the 36 prescription hearing aids we've evaluated. In our testing, this device shows a mixed performance profile. Own-voice comfort is a clear strength, scoring 3.5/5—0.75 points above the category average—making it a solid choice for users who prioritize natural sound quality when speaking. Feedback handling is excellent at 4.8/5, slightly above the category average, indicating stable performance during typical daily activities. However, speech-in-noise performance is notably limited, scoring just 1.1/5—0.82 points below the category average of 1.96. This is a meaningful weakness for users who frequently encounter noisy environments like restaurants or social gatherings. Speech in quiet is solid at 3.2/5, though slightly below the category average. Music streaming scores 2.8/5, above average but only mixed in absolute terms. At this price point, buyers should consider alternatives. The Rexton Reach R-Li T80 at Costco scores 4.58/5 in the same price range, while lower-priced options like the Lexie B3 (4.76/5) offer stronger overall performance. The Jabra Enhance Pro 20 may suit users who prioritize own-voice comfort and feedback stability over challenging listening environments, but those needing robust noise handling should explore other options.

These results suggest the Sphere Infinio Ultra prioritizes speech clarity across challenging listening environments. Music streaming quality is solid at 3.3/5, sitting 0.66 points above the category average. Own voice comfort scored 2.8/5, which is above the category average but remains mixed in absolute terms—listeners sensitive to occlusion may notice this limitation.

The Sphere Infinio Ultra is best suited for users who prioritize speech understanding, particularly in noisy environments, and who are prepared to invest in premium technology. Those seeking the highest feedback stability or improved own-voice comfort may want to compare alternatives, though this device's speech performance stands out as a category leader.
