Quick Answer: Otofonix currently sells five FDA-registered OTC hearing aid models — Elite, Encore, Helix, Revive, and the flagship Groove — priced from about $197 on sale (regular prices $394-$1,590 depending on model), per otofonix.com. The only model with published independent lab data, the Helix, scored a “C” grade (SoundScore 2.6/5) from HearAdvisor and ranked 7th of 8 devices in its category for speech clarity. Otofonix also sells a separate personal sound amplifier (the Apex) that is not an FDA-regulated hearing aid — don’t confuse the two when shopping.

Otofonix shows up as a passing mention on this site’s best hearing amplifiers guide, where the Apex is our pick for best wearable amplifier — but that’s a different product category from Otofonix’s actual OTC hearing aid lineup, which has never had its own review here. Here’s what the brand’s hearing aids cost, what independent testing found, and how the naming overlap between “Otofonix hearing aids” and “Otofonix Apex” can trip up a search.

1. Otofonix Elite — The Budget Entry Point

Otofonix Elite

Entry-level OTC hearing aid · from $197 · battery or rechargeable options
  • The cheapest current model in the lineup, with background noise reduction aimed at mild-to-moderate hearing loss.
  • Available in both disposable-battery and rechargeable versions, giving budget shoppers a choice most sub-$250 OTC devices don't offer.
  • No independent lab test has been published for the Elite specifically — treat performance claims with the same caution HearAdvisor's Helix results suggest for the brand generally.

2. Otofonix Encore — The Telecoil Pick

Otofonix Encore

Telecoil-equipped OTC hearing aid · from $197 · dual directional mic, 10 volume levels
  • The only current Otofonix model with a telecoil, letting it connect directly to hearing loops in theaters, places of worship, and some phones — a feature most budget OTC brands skip.
  • Dual directional microphones and advanced digital noise cancellation, with 10 manual volume levels for finer control than single-button budget devices.
  • Same caveat as the Elite: no independent lab test published specifically for the Encore.

3. Otofonix Helix — Newest, Most Powerful, and the Only Lab-Tested Model

Otofonix Helix

Rechargeable OTC hearing aid · from $197 · HearAdvisor "C" grade, SoundScore 2.6/5
  • Otofonix's newest and most powerful model, rechargeable and marketed as the brand's flagship performance pick before the Groove's release.
  • HearAdvisor's independent lab test is the only third-party data point available for any current Otofonix hearing aid — and it's not flattering: a "C" overall grade, SoundScore 2.6/5, ranked 7th of 8 devices tested in its Amplification Product category.
  • The Helix's individual scores were lopsided: speech-in-quiet and speech-in-noise both landed at 1.0/5 (its weakest results), while feedback/whistling handling scored a perfect 5.0/5 (its strongest) — good at not squealing, weaker at the core job of clarifying speech.

Otofonix hearing aids vs. the Otofonix Apex amplifier

The naming overlap here causes real confusion: someone searching “Otofonix hearing aids” can land on either the five FDA-registered OTC hearing aid models above or the Otofonix Apex, a personal sound amplification product (PSAP) that isn’t a medical device and isn’t held to the FDA’s OTC hearing aid regulation. Otofonix itself markets the Apex to people “not quite ready” to commit to a hearing aid — it’s a legitimate, useful category of device, just a different one. We review the Apex on its own in our best hearing amplifiers guide, where it’s our pick for best wearable amplifier. If a listing just says “Otofonix” without naming Elite, Encore, Helix, Revive, or Groove specifically, check which category you’re actually buying into.

Before you buy: the OTC ground rules

Otofonix’s five hearing aid models are FDA-registered OTC devices for adults with perceived mild-to-moderate hearing loss — a self-assessed category, not a clinical diagnosis. The separate Apex amplifier isn’t a medical device at all. Anyone with severe, sudden, or one-sided hearing loss, ear pain, drainage, or pulsing tinnitus should see a hearing professional rather than starting with any OTC device or amplifier, Otofonix included.

The bottom line

Otofonix sells a real, FDA-registered OTC hearing aid lineup — Elite, Encore, Helix, Revive, and Groove — priced from about $197 on sale, plus a separate PSAP (the Apex) that’s a different product entirely. The only independent lab data available, on the Helix, landed a “C” grade and 7th-of-8 category ranking, weakest on the speech clarity that matters most day to day. If you want the telecoil for hearing loops, the Encore is the obvious pick in this lineup; if you want independently-verified performance first, Audien or LINNER currently have stronger third-party test results.
