Jabra Enhance Pro 20 at Costco
The Jabra Enhance Pro 20 at Costco is a behind-the-ear prescription hearing aid priced at $1,600, placing it in the premium tier. With a SoundScore of 4.0/5 and an A grade, it ranks #25 of 39 prescription hearing aids tested in our lab. In our testing, this device demonstrates notable strengths in own-voice comfort, scoring 3.5/5—0.80 points above the category average. This solid performance means wearers may find their own voice sounds more natural compared to many competitors. Feedback handling is excellent at 4.8/5, slightly above the category average, indicating reliable stability during movement and phone use. However, the Enhance Pro 20 shows limitations in challenging listening environments. Speech-in-noise performance scores just 1.1/5, falling 0.97 points below the category average—a significant gap that may affect conversations in restaurants, social gatherings, or other noisy settings. Speech-in-quiet is solid at 3.2/5 in absolute terms, though still 0.17 points below the category average. Music streaming scores 2.8/5, which is above the category average but only mixed in absolute terms. This device suits users who prioritize comfortable own-voice perception and excellent feedback control, and who spend most listening time in quieter environments. Those frequently navigating noisy situations may want to consider alternatives like the Rexton Reach R-Li T80 at Costco, which scored 4.56/5 in our testing. The Enhance Pro 20 includes rechargeable batteries, iPhone and Android streaming, and hands-free functionality.

Oticon Zeal
The Oticon Zeal is a premium prescription hearing aid in the invisible-in-ear style, carrying an A grade with a SoundScore of 4.7/5 in our lab testing. Priced at $4,798, it ranks #6 among 39 prescription hearing aids tested, placing it in the top 13% of its category. Speech performance is where the Zeal truly excels. Our testing measured an excellent 4.9/5 for speech in quiet—1.48 points above the category average—making it one of the strongest performers for everyday conversations. Speech in noise also scores a solid 3.0/5, sitting 0.93 points above the category average of 2.11/5, indicating reliable performance in moderately challenging listening environments. Music streaming quality registers at a solid 3.3/5, which is 0.54 points above the category average. However, the Zeal shows some limitations in other areas. Own-voice comfort scores a mixed 2.0/5, falling 0.70 points below the category average—something to consider if own-voice naturalness is a priority. Feedback handling measures at 3.3/5, which is solid in absolute terms but sits 1.42 points below the category average of 4.72/5. The Oticon Zeal is best suited for wearers who prioritize exceptional speech clarity and want a discreet, invisible-in-ear form factor. Those especially sensitive to feedback or own-voice effects may want to discuss these trade-offs with their hearing care provider during fitting.
