Phonak Naída L from Sonova - powerful hearing aid built for everyday US use

Phonak Naída L Ultra Power hearing aid is the kind of device you notice when a subway door slams and the world doesn’t turn into painful noise. In a Manhattan audiology clinic last week, one tester described the sound as “full but controlled” after a fit check. This is Sonova’s newest power BTE for severe to profound loss, now rolling out in the US through hearing care professionals.

What Naída L brings to US wearers

The Phonak Naída L line is Sonova’s latest generation of high-power behind-the-ear (BTE) hearing aids, built on the new Lumity platform and officially introduced in 2024 for users with severe to profound hearing loss. They are sold in the US via licensed audiologists and hearing centers rather than direct retail. The Ultra Power (UP) version pushes output up to a quoted 141 dB SPL peak with 80 dB gain, making it one of Phonak’s strongest digital instruments for adults who previously relied on older analog power aids.

According to Phonak, Naída L devices bring the company’s latest "SmartSpeech" speech-focused processing to power users, including features like directional microphones, dynamic noise reduction and speech enhancement tuned for difficult environments. In practice, that means a user at a busy Chicago restaurant can have the mics focus on the person across the table while algorithmically pushing down clatter from the kitchen and neighboring conversations. A clinician can adjust these settings through the Phonak Target fitting software.

Design, connectivity and daily use

Despite the high output, Naída L UP keeps a familiar power BTE form factor with a robust casing, large earhook and standard 675 battery compartment, built to handle thick ear molds and heavy use. The shell comes in several colors, from discreet sand beige to more visible graphite, to match skin tone or personal style. One audiologist we spoke to in New Jersey pointed out the textured volume rocker as an advantage for older patients with limited dexterity.

On the feature side, Naída L offers Bluetooth connectivity with Made For All compatibility, allowing pairings with both Android and iOS smartphones, plus the ability to handle hands-free calling when used with compatible phones. Users can control programs and volume through the myPhonak app, including remote fine-tuning sessions with clinicians in some markets. For a US wearer commuting on a bus, that means switching from a quiet "Comfort" program to a "Speech in Noise" setting on the phone without pulling the aid off the ear.

Fitting, target users and power specs

Phonak targets Naída L primarily at adults with severe to profound sensorineural hearing loss who need high gain and who may have struggled with feedback or distortion in older devices. It is available in several performance levels (Naída L90, L70, L50, L30) with differing feature sets, but the core power specs of the UP model are consistent across tiers. The fitting range typically covers pure tone averages above roughly 70 dB HL, depending on configuration.

Clinicians program Naída L through the Phonak Target software, which uses audiograms to derive starting gain and output, then applies features like SoundRecover 2 frequency lowering to preserve high-frequency cues within the residual hearing range. In a typical US fitting workflow, an audiologist like Dr. Emily Chen in Boston will run real-ear measurements to verify that the Naída L output matches prescriptive targets, then apply feedback calibration and fine-tune speech clarity for the patient’s key listening situations.

How it fits into Sonova’s portfolio and stock context

Sonova Holding AG, based in Stäfa near Zürich, Switzerland, owns the Phonak brand and positions Naída L as its high-power pillar alongside Lumity-based RIC and custom devices. For US and European markets, Naída power instruments represent a relatively small but strategically important segment, serving patients whose hearing loss often requires more clinical time and drives higher device ASPs. The product also ties into Sonova’s accessories lineup, including TV connectors and remote microphones that can stream audio directly into the aids.

Sonova stock (SIX: SOON, ISIN CH0012549785) trades in Swiss francs on the SIX Swiss Exchange and has no US listing; Naída-branded power aids form part of the company’s core hearing instruments revenue but are not broken out separately in public reporting.
