Since the FDA's OTC rule took effect in October 2022, the consumer market has organized into four broad product categories.
Self-fitting in-canal
Small, often invisible devices that calibrate to the wearer through an in-app hearing test and frequency-band tuning. Best for adults comfortable with smartphones and looking for discretion. Trade-off: tighter fit can feel occluded at first.
Example: Panda Stealth ($279) — near-invisible ITC, 16-channel processing, three preset modes, no app required.
Self-fitting behind-the-ear (BTE / RIC)
The receiver-in-canal form factor used by most prescription hearing aids, now available OTC. Better suited to higher-frequency loss and longer battery life. Trade-off: more visible.
Example: Panda Quantum ($349) — RIC, 16-channel WDRC, frequency-matched amplification, tinnitus masking.
Preset OTC amplifiers
Devices that ship with a small number of fixed sound profiles — no in-app test. Often the lowest-priced category. Trade-off: limited personalization, often a worse fit for asymmetric or sloping loss.
Examples: Audien Atom, MDHearing Volt — entry-level preset amplifiers commonly seen at $99–$300.
Earbud-style OTC devices
Hearing-aid-grade processing inside earbud hardware (in some cases also functioning as Bluetooth headphones). Useful for adults who want to ease into hearing support. Trade-off: shorter daily wear time and bigger fit.
Examples: Panda Air ($299) and Apple AirPods Pro 2 with the FDA-authorized Hearing Aid Feature ($249).
