Feedback handling is excellent at 5.0/5, meaning users should experience stable performance without whistling during typical wear. Own-voice comfort also performs well at 3.5/5, nearly a full point above average, which can contribute to a more natural listening experience. Speech understanding in noisy environments presents a limitation, scoring 1.5/5—essentially at the category average but low in absolute terms. This is a common challenge across OTC devices, though users seeking strong noise performance may want to compare alternatives. Music streaming scores 2.6/5, which is above the category average by 0.68 points but mixed in absolute quality. The Enhance Select 300 offers rechargeable batteries and streaming compatibility with both iPhone and Android devices, along with hands-free functionality. It has earned Expert's Choice Awards in both 2023 and 2024. Shoppers in this price range should note that alternatives like the Lucid Tala and Audicus Omni 2 score higher overall, while options like the Jabra Enhance Pro 20 at Costco offer similar sound quality at a lower price point. This device is best suited for those prioritizing speech clarity in quieter settings and stable, feedback-free performance.
