Phonak Slim launched in early 2023 with a distinctly new form factor. On the inside, Slim is exactly like the rest of the Lumity Family, with strong background noise management and an industry-leading Bluetooth connection. Lumity is currently the top-selling hearing aid in the U.S.

Lumity Slim is all about design. Slim has a rebuilt portable recharging case, a single push button on each device, and several tech-forward colors.

Like the rest of the Phonak Lumity family, Slim devices allow hands-free phone calls using both Android and iPhone. The device has impressive listening tech onboard, including a motion sensor that focuses sound when seated and gives 360° listening when you walk around.

Unlike most hearing aids, Lumity Slim designates a right and left hearing aid with a 7-degree contour on each side to ensure a comfortable fit. The design leaves more room for glasses, masks, or oxygen tubes.

Pros 👍
  • Innovative modern design
  • Top of the line customization, Bluetooth connection and rechargeable batteries
  • Enhanced background noise reduction
  • Highly water-resistant option available for active lifestyles

Cons 👎
  • Lumity Slim is a premium product with a premium price
  • Phonak's app can be more finicky then other models

There’s a new hearing aid in town, and it will make you rethink what you know about hearing health design.

Today Phonak announced a new hearing aid design called Phonak Slim. The name quickly reveals what the leading hearing brand has in store.

Phonak Slim runs on the same technology as the flagship product Phonak Lumity but with a new streamlined design meant to challenge hearing aid design convention and leave more room behind your ears (big for anyone with glasses or oxygen).

Let’s Start with a Close Up on The Product Design 

While most hearing aids look virtually the same on the right and left, Phonak Slim contours to the head with a 7-degree bend that hugs your head and ears on each side. 

The unique design also gets a special charging case with a slightly contoured right and left charger. 

Phonak Slim comes in four two-tone colors, including: Graphite/Black, Coppy/Black, Sandalwood/Black, and Silver/Black.

Phonak Slim also includes a low-profile pushbutton for easy volume and program updates. This sets Phonak Slim apart from Signia Styletto (the only comparable design), which does not have a button. 

What’s underneath this sleek new exterior? 

Phonak made a point to launch Phonak Slim under the same tech platform as their flagship product, Phonak Audéo Lumity.

Lumity was released in late 2022 with a focus on background noise management. Lumity helps cut through background noise in a few ways. The first is a new operating system (the brain of the hearing aid) called AutoSense OS 5.0.

This new automatic operating system uses machine learning and scans the environment 700 times per second for real-time adjustment. Those rapid adjustments mean the hearing aid can shift modes quickly when your environment gets louder. 

Lumity also adds new special features focused on background noise, StereoZoom 2.0, and SpeechSensor. StereoZoom 2.0 enhances the sound of the person in front of you over the background noise; this leads to a better understanding of speech. 

Phonak Slim inherits some of Lumity’s favorite connection features, such as tap-control, hands-free calling on Android and iPhone devices, and a more stable Bluetooth classic connection. 

Phonak Slim hearing aids will access the same myPhonak app as other devices.
