Autiphon U0 Series Expert Review

The Autiphon U0 Series is a budget-priced amplification product available for $99, earning a C grade in HearAdvisor's lab testing. As a visible-in-ear device with rechargeable batteries, it offers basic amplification at an entry-level price point.

In our lab testing, the Autiphon U0 Series showed mixed results. Its standout strength is feedback handling, scoring a perfect 5.00/5—well above the category average. This means users are unlikely to experience the annoying whistling that can plague some amplification products. However, speech intelligibility performance was below average, with speech in quiet and speech in noise scores both measuring 1.90/5 and 1.10/5 respectively.

Notably, this device lacks adjustability—the initial and tuned fit conditions produced identical results, as there are no professional fitting options or customization parameters available. This is typical for budget amplifiers but means the device cannot be optimized for individual hearing needs. Music streaming and own-voice measurements were not applicable for this product category.

The Autiphon U0 Series competes directly with other budget options like the HSKLock Hearing Aid (scored 2.84/5) and Otofonix Elite (scored 1.46/5). While it falls slightly behind the HSKLock in overall performance, it significantly outperforms the Otofonix Elite. This device may suit consumers seeking an affordable entry point into amplification with reliable feedback control, though those prioritizing speech clarity should consider higher-performing alternatives.
