Jabra Enhance Select 300 Hero
JabraSoundScore 4.1Grade A

Jabra Enhance Select 300

The Jabra Enhance Select 300 is a premium OTC hearing aid priced at $1,695 that earns an A grade with a SoundScore of 4.1/5 in our lab testing. This behind-the-ear device ranks #17 among 65 OTC hearing aids tested, placing it in the top 25% of its category. In our testing, the Enhance Select 300 demonstrates notable strengths in speech clarity for quiet environments, scoring 0.85 points above the OTC category average. Feedback handling is excellent at 5.0/5, and own-voice comfort scores a solid 3.5/5—nearly a full point above average for the category. Music streaming performance, while above average for OTC devices, remains mixed in absolute terms at 2.6/5. The device's main limitation appears in challenging listening environments. Speech-in-noise performance scored 1.5/5, which is low in absolute terms and essentially matches the category average. Users who frequently encounter noisy restaurants, busy offices, or crowded gatherings may find this a meaningful constraint. The Enhance Select 300 is best suited for individuals who primarily need improved hearing in quieter settings such as home conversations, one-on-one meetings, or watching television. It offers reliable streaming to both iPhone and Android devices, rechargeable batteries, and hands-free functionality. Shoppers seeking stronger noise performance at this price point may want to compare alternatives like the Lucid Tala or Audicus Omni 2, which scored higher overall in our testing.

Olive Union Air

The Olive Union Air is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.9/5 in our lab testing, placing it in the top 31% of OTC hearing aids at #21 of 65 devices tested. At $250, it represents a competitive entry point in the over-the-counter hearing aid market. In our testing, this visible-in-ear style device demonstrated notable strengths in music streaming, scoring 3.6/5—a solid result that sits 1.67 points above the OTC category average. Feedback handling was excellent at 5.0/5, meaning users should experience minimal whistling or squealing during normal use. Speech understanding in quiet environments also performed well at 3.3/5, measuring 0.46 points above the category average. The Olive Union Air does show limitations in more challenging listening situations. Speech in noise scored 1.0/5, falling 0.48 points below the category average—a common weakness among budget OTC devices that may affect conversations in restaurants or busy environments. Own-voice comfort measured 2.2/5, slightly below average, which some users may notice when speaking. This device is best suited for individuals who prioritize music and media streaming, need reliable feedback control, and primarily listen in quieter environments. Those who frequently encounter noisy social situations may want to consider devices with stronger speech-in-noise performance.
