Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Jabra Enhance Select 700
The Jabra Enhance Select 700 is a premium-priced OTC hearing aid available at $1,795, earning a B grade with a SoundScore of 3.8/5 in our lab testing. This behind-the-ear device ranks #26 of 65 OTC hearing aids tested, placing it in the top 38% of the category. In our testing, the Enhance Select 700 showed notable strengths in comfort-related metrics. Own-voice comfort scored a solid 3.7/5, measuring 1.19 points above the category average—a meaningful advantage for wearers sensitive to the sound of their own voice. Feedback handling was excellent at 5.0/5, well above the 4.54 category average, indicating reliable stability during typical wear. Speech performance presented a mixed picture. Speech in quiet scored a solid 3.1/5, sitting 0.27 points above average. However, speech in noise was a weakness at 1.0/5, falling 0.48 points below the category average—an important consideration if challenging listening environments are a priority. Music streaming scored 2.5/5, which is above the category average by 0.58 points but only mixed in absolute terms. At this price point, several alternatives delivered stronger overall performance in our testing, including the Lucid Tala (4.61/5) and Audicus Omni 2 (4.59/5). The Jabra Enhance Select 300 and Lucid Engage also achieved higher scores at lower prices. The Enhance Select 700 may suit those prioritizing own-voice comfort and feedback stability over speech-in-noise performance, but shoppers should weigh these trade-offs carefully given the premium pricing.

Signia Silk Charge&Go IX
The Signia Silk Charge&Go IX is a premium prescription hearing aid featuring an invisible-in-ear design, currently available at $3,298. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #32 of 39 prescription hearing aids tested. This device demonstrates a notable strength in speech clarity for quiet environments, scoring an excellent 4.6/5—well above the category average by 1.22 points. Speech in noise performance is mixed at 2.2/5, though this still edges slightly above the category average. Feedback handling is strong at 4.3/5, providing reliable stability during typical wear, even if it falls just below the category average. The Silk Charge&Go IX has significant limitations to consider. Own-voice comfort scores low at 1.5/5, falling 1.20 points below the category average—a trade-off that may relate to the invisible form factor. Most notably, the device does not support music streaming, scoring 0.0/5 in that metric, which is 2.76 points below the category average. At this premium price point, several competitors deliver substantially higher overall performance, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Silk Charge&Go IX is best suited for users who prioritize an invisible, rechargeable design and primarily need clear speech understanding in quieter settings, while having minimal need for streaming audio content.
