Audien Hearing Atom

The Audien Hearing Atom is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in HearAdvisor's lab testing. At $89, it's positioned as an entry-level option in the visible-in-ear category, ranking #52 of 65 OTC hearing aids tested. In our testing, the Atom demonstrates mixed results across key performance areas. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable performance without whistling or squealing during typical wear. However, speech clarity metrics fall below category averages: speech in quiet scores 2.6/5 (0.15 points below average) and speech in noise scores a low 1.0/5 (0.48 points below average), which may limit effectiveness in challenging listening environments. The Atom does not support music streaming, scoring 0.0/5 in this category—1.92 points below the OTC average. Own-voice comfort is mixed at 2.1/5, sitting 0.41 points below the category average. These limitations are notable when compared to similarly-priced alternatives like the Elehear Beyond (4.36/5) or Apple AirPods Pro 2 (4.06/5), which offer substantially stronger overall performance. This device may suit budget-conscious consumers who prioritize basic amplification and feedback-free wear over speech clarity in noise or streaming capabilities. Those seeking stronger speech performance or music features should consider higher-scoring alternatives in this price range.

Phonak Sphere Infinio Ultra

The Phonak Sphere Infinio Ultra is a premium behind-the-ear prescription hearing aid priced at $4,898. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.9/5, placing it in the top 3% of the 36 prescription hearing aids tested and ranking #2 in its category. This device delivers exceptional speech performance in our testing. Speech in noise scored an excellent 4.5/5, a remarkable 2.55 points above the category average of 1.96/5—one of the largest margins we've measured in this critical metric. Speech in quiet also performed strongly at 4.3/5, exceeding the category average by 1.00 point. 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. Feedback handling measured 4.2/5, which is strong in absolute terms though 0.51 points below the category average of 4.71/5. 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.
