Audien Atom Pro 2 vs Phonak Sphere Infinio

The Audien Atom Pro 2 is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in our lab testing. At $289, it sits in the lower price tier of the OTC category, though several competitors at similar or lower prices deliver stronger overall performance. In our testing, the Atom Pro 2 showed a clear strength in feedback handling, scoring an excellent 5.0/5—0.46 points above the category average. This means users are unlikely to experience whistling or squealing during normal wear. However, the device showed mixed results for speech clarity, with speech in quiet scoring 2.3/5 (0.49 points below category average) and speech in noise at 1.3/5 (0.16 points below average). Own-voice comfort was slightly above average at 2.6/5, though still mixed in absolute terms. The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Users who want to stream phone calls or music through their hearing aids should consider alternatives like the Olive Union Air or Elehear Beyond, which offer substantially better streaming performance. The Atom Pro 2 may suit budget-conscious buyers who prioritize basic amplification without feedback issues and don't need streaming functionality. However, shoppers in this price range should also consider the Linner Saturn or Olive Union Air, which offer similar or better sound performance at lower prices.
