Widex Evoke BTE 13 Direct (MFi) EBB3D Series: A Complete Product Description

What Is the Widex Evoke BTE 13 Direct?

The Widex Evoke BTE 13 Direct is a behind‑the‑ear (BTE) hearing aid from the Evoke™ family, available in four technology levels: EBB3D 440, EBB3D 330, EBB3D 220 and EBB3D 110. The “BTE” design places the main body comfortably behind your ear, connected to a thin tube or standard earmould. The “13 Direct” designation indicates the device uses a disposable size 13 zinc‑air battery — not a size 10 battery, which is an important clarification — and features direct 2.4 GHz wireless streaming from iOS devices via its built‑in Bluetooth technology. Designed for individuals with mild to moderately severe hearing loss, the Evoke BTE 13 Direct offers a fitting range of 0‑105 dB HL across all four technology levels.

A brief note on battery size: In the initial request, the battery was listed as size 10. However, the official Evoke BTE 13 Direct specifications confirm it uses a size 13 (orange‑tabbed) battery. This model is not available in a size‑10 configuration. The description below reflects the correct, verified specifications.

The Core Smart Technology: SoundSense Machine Learning

What truly sets Evoke apart is its SoundSense Technology, the world’s first machine‑learning platform integrated into a hearing aid. Every time you use Evoke, it evolves — because it learns from the adjustments you make in different sound environments and applies that knowledge to similar situations in the future. This is achieved through two complementary features:

• SoundSense Learn – When you encounter a challenging listening situation, the Evoke app presents you with two alternative sound profiles (A vs B). Simply listen and select your preferred option. Repeat this process as many times as you wish, and the hearing aid gradually builds a personalised sound model tailored to your unique hearing preferences. The system uses anonymised data from users worldwide to continuously improve its recommendations.

• SoundSense Adapt – The hearing aid remembers every adjustment you have ever made and intelligently applies those preferences to new environments — even if you have never visited that particular location before. Your Evoke never forgets, and it constantly applies what it has learned to deliver better sound automatically.

Underpinning these features is the powerful Fluid Sound Controller, a dual‑core processing system that continuously analyses incoming sound and automatically adjusts multiple parameters — including variable‑speed compression — to preserve natural sound quality while reacting quickly to dynamic acoustic environments. The Fluid Sound Analyzer maps out your environment into distinct sound classes and selects the optimal settings in real time.

Technology Levels: 440, 330, 220 and 110

The Evoke BTE 13 Direct is offered in four distinct performance levels. The number indicates the sophistication of the feature set, with 440 being the most advanced and 110 the essential entry level.

Widex Evoke EBB3D 440 – Flagship Performance

The EBB3D 440 is the most technologically advanced option in the Evoke BTE line. It features 15 processing channels for exceptionally precise sound shaping and 11 distinct sound classes that automatically identify your listening environment — from quiet conversation to a crowded restaurant or music concert — then apply the optimal settings for each. The 440 includes six listening programs, the most advanced version of the machine‑learning algorithms, and the full suite of noise‑management features, including advanced wind noise reduction and impact‑sound softening. It is ideal for users who face complex listening environments daily.

Widex Evoke EBB3D 330 – Advanced Everyday Intelligence

The EBB3D 330 offers 12 processing channels and a high degree of adaptability for most daily situations — from family gatherings to outdoor conversations. It retains all the core smart features, including SoundSense Learn and Adapt, the full Fluid Sound Controller, and up to four listening programs. The 330 level is an excellent choice for users who want strong performance across varied environments without needing the absolute highest feature density.

Widex Evoke EBB3D 220 – Solid Mid‑Range Choice

The EBB3D 220 is a reliable option for users with quieter lifestyles or those who want core Evoke intelligence at a more accessible price point. It offers 10 processing channels, up to three listening programs, and the essential noise‑management features. The 220 still includes the full machine‑learning personalisation capabilities and the Fluid Sound Controller, making it a capable performer in most everyday listening situations.

Widex Evoke EBB3D 110 – Essential Smart Hearing

The EBB3D 110 provides core Evoke sound quality with streamlined features — ideal for first‑time users or those who primarily need amplification in quiet to moderately quiet environments. It comes with 6 processing channels and up to three listening programs. While it lacks some of the advanced directionality and noise‑management features of higher levels, it still includes SoundSense Learn and Adapt, TrueInput technology, dynamic feedback cancellation, and variable‑speed compression. Users can still stream directly from iOS devices and control the hearing aid via the Evoke app.

Features Common to All Four Levels

Across all technology levels, the Widex Evoke BTE 13 Direct shares a robust core of essential technologies:

• Direct Audio Streaming from iOS Devices (MFi) – Stream phone calls, music, podcasts and videos directly from iPhones to your hearing aids without an intermediary device, thanks to 2.4 GHz wireless technology.

• TrueInput Technology – An expanded input range of 113 dB SPL, handling very loud sounds without distortion while preserving soft sounds. This broad dynamic range means you can hear the softest speech clearly while loud, unexpected noises remain comfortable and never become harsh or overwhelming.

• Dynamic Feedback Controller – Fast, artefact‑free cancellation of whistling feedback, engineered to adapt and preserve sound quality.

• Variable‑speed compression – Automatically adjusts from fast to slow for consistent speech understanding and listening comfort at all input levels.

• ZEN Tinnitus Management – A built‑in tinnitus relief tool using soothing fractal tones, available on all levels.

• Telecoil – Connect easily to induction loop systems in theatres, places of worship and public venues.

• Programmable push button – Customisable for short or long presses to change programs, adjust volume or answer calls.

• IP68 dust/water protection – The device is resistant to dust and can withstand immersion in water, making it suitable for active users.

• Widex Evoke App – Full control over volume, programs and personalisation, plus access to SoundSense Learn. The app is available for both iOS and Android devices.

• DEX accessory compatibility – Works with TV Play 2 (direct TV streaming), RC‑DEX (simple remote control) and COM‑DEX (hands‑free streaming from any Bluetooth phone).

What Is Not Included (Honest Disclosure)

The Widex Evoke BTE 13 Direct does not include:

• Direct streaming from Android devices – If you use an Android phone, you will need a separate COM‑DEX accessory to stream audio, because this model lacks native ASHA support for direct Android connectivity.

• Hands‑free calling – The hearing aid microphones are not used for phone calls; you must speak into your phone.

• Rechargeable battery – This model uses disposable size 13 batteries only.

• Ultra‑fast PureSound™ processing (<0.5 ms) – Found in newer Widex Moment models, Evoke uses 2.5 ms processing, which still delivers excellent sound quality.

• AI Sound Assistant – The machine learning in Evoke is based on SoundSense (user‑guided) rather than the fully automated AI assistant found in later generations.

Battery Life and Physical Design

The size 13 battery provides extended runtime — typically 7‑14 days of use depending on streaming activity and amplification demands. Even with frequent streaming, the battery life remains robust. The hearing aid features a battery door that doubles as an on/off switch: open the door to power down, close it to turn it on. Audible low‑battery warnings indicate when a replacement is needed.

The Evoke BTE 13 Direct is supplied in a standard beige colour, with other colour housing options available subject to delivery lead time. The device can be configured with either a classic hook for use with a custom earmould or thin tubes for open‑fit domes, offering flexibility to match your hearing loss profile and cosmetic preferences. The push button is large and easy to locate, making it ideal for users with dexterity challenges.

Who Is It For?

The Widex Evoke BTE 13 Direct is best suited for iPhone users with mild to moderately severe hearing loss (up to 105 dB HL) who want a durable, easy‑to‑handle BTE with direct streaming, long battery life, and machine‑learning personalisation — at a more accessible price than newer Moment or Allure models. Choose the EBB3D 440 for flagship performance with 15 channels and 11 sound classes; EBB3D 330 for advanced everyday intelligence; EBB3D 220 for solid mid‑range value; and EBB3D 110 for essential smart hearing at the most accessible price.
