Widex Evoke Power BTE FP Series – A Complete Product Description

The Widex Evoke Power BTE FP series — comprising the FP 440, FP 330, FP 220 and FP 110 — is a behind‑the‑ear Power BTE hearing aid from the Evoke™ family, the world’s first platform to integrate live machine learning. Evoke learns directly from your sound‑preference choices in real‑world environments, delivering a continuously improving, personalised listening experience.

The “Power BTE” form factor is specifically engineered for moderate to moderately severe hearing loss, offering a fitting range of 20–110 dB HL across all four technology levels. It is built around a size‑13 (orange‑tab) disposable battery, which provides the longest battery life of any Widex device – up to 280 hours of continuous use, equivalent to approximately 18 days of typical daily wear (about 16 hours per day). The device connects to a conventional earhook with a custom earmold – either hard or soft – ensuring a secure, comfortable fit and optimal acoustic seal for high‑gain applications where standard domes cannot provide sufficient retention or feedback control. It carries an IP68 dust‑ and water‑resistance rating. The Power BTE design is therefore an excellent choice for users who require high levels of gain, value long‑lasting battery operation, and prefer the durability and ease of handling of a conventional BTE device.

Important note on wireless streaming: The Widex Evoke Power BTE FP series (the 2.4 GHz version) supports direct audio streaming from iOS and compatible Android devices. Unlike the non‑wireless FM/FA versions, the FP series includes built‑in 2.4 GHz Bluetooth, enabling you to stream phone calls, music, podcasts and videos directly from your smartphone to your hearing aids. Two‑way audio calls are also possible with compatible iPhones.

🧠 The Core Intelligence: SoundSense Technology

What truly sets Evoke apart is its SoundSense Technology – the world’s first machine‑learning platform built into a hearing aid. It works 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). You can repeat this comparison as many times as you like. Over time, the device constructs a completely personalised sound model based on your own listening tastes. The system uses anonymised data from thousands of users worldwide to make smart recommendations.

• SoundSense Adapt – The hearing aid never forgets any adjustment you have ever made. It intelligently applies your past choices to similar new environments – even places you have never visited before. Your Evoke constantly refines itself automatically, without any manual intervention.

Underpinning these features is the Fluid Sound Controller, a dual‑core processing system with access to more sound parameters than any previous Widex hearing aid. The system continuously analyses incoming sound and automatically adjusts multiple parameters – including variable‑speed compression – to preserve natural sound profiles while reacting quickly to dynamic acoustic environments. Paraphrased: The Fluid Sound Analyzer continuously categorises your listening environment into different types (such as quiet, speech with background noise, parties, traffic, city noise, music, and more), then automatically applies the most suitable settings without any delay.

📊 Technology Levels at a Glance

The Evoke Power BTE FP series is offered in four distinct performance tiers. The number indicates the sophistication of the feature set, with 440 being the most advanced and 110 the essential entry level. All models use the same size‑13 disposable battery with a fitting range of 20–110 dB HL.

🔍 Detailed Breakdown by Level

🟢 Widex Evoke FP 440 – Flagship Performance

The FP 440 is the most technologically advanced option in the Evoke Power BTE line. It features 15 processing channels for exceptionally precise sound shaping across the entire frequency spectrum, and the highest number of sound classes available on the Evoke platform. The FP 440 includes advanced directionality features for maximum speech intelligibility in challenging noise, and up to five listening programmes. It features advanced variable‑speed compression and advanced wind noise management for superior sound quality in dynamic outdoor environments. The FP 440 is ideal for users who face complex, changeable listening environments daily – from busy restaurants to outdoor markets and public transport.

🟡 Widex Evoke FP 330 – Advanced Everyday Intelligence

The FP 330 offers 12 processing channels and a high degree of adaptability for most daily situations – from family gatherings to outdoor conversations. It retains advanced directionality, up to four listening programmes, and advanced wind noise management. The FP 330 is an excellent choice for users who want strong performance across varied environments without needing the absolute highest feature density.

🟠 Widex Evoke FP 220 – Solid Mid‑Range Choice

The FP 220 provides a dependable core of Evoke intelligence for users with quieter lifestyles or those who want essential smart features at a more accessible price point. It uses 10 processing channels and the full TriLink Technology architecture. It includes Broadband Locator for effective speech‑in‑noise handling, but lacks the advanced fine‑grained directionality of the higher tiers. Up to three listening programs are available. The FP 220 is perfect for users who want the learning intelligence of Evoke without the more sophisticated noise‑management and directionality features of the premium levels.

🔵 Widex Evoke FP 110 – Essential Smart Hearing

The FP 110 is the entry point into Evoke machine learning – 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 programmes. It includes core features such as Broadband Locator (basic version), variable‑speed compression, and basic wind noise control. While it lacks the advanced directionality and richer noise‑management features found in the higher tiers, it still provides the complete SoundSense Learn & Adapt experience – meaning even the Essential model learns from your preferences and continuously improves its performance over time.

🔋 Battery Life and Physical Design

All Evoke Power BTE FP models operate on a size‑13 (orange‑tab) disposable battery – one of the largest hearing aid battery sizes available. A single battery provides approximately 280 hours of continuous use, which equates to roughly 18 days of normal daily wear (about 15–16 hours per day) before a replacement is needed. This is the longest battery life of any Widex device, making the Power BTE exceptionally practical for users who travel, who do not wish to manage daily charging or frequent battery changes, or who may have difficulty handling tiny batteries. The hearing aid features a battery door that doubles as an on/off switch – flipping it open turns the hearing aid off, while closing it switches the aid back on. Audible low‑battery warnings indicate when a replacement is needed. No charging equipment is required.

All Evoke Power BTE FP hearing aids carry an IP68 rating – the highest dust and water resistance classification. They are protected against dust ingress and can withstand immersion in water, giving you confidence to wear them during gentle exercise, in light rain, or in other moderately demanding outdoor situations without concern.

The Power BTE form factor is noticeably larger than standard BTE and much more powerful. It is designed to be fitted with an earhook and a conventional custom earmold (either hard or soft) rather than thin tubes and domes. This configuration ensures a tight acoustic seal essential for high‑gain applications where feedback control is critical. The device comes in a standard beige colour, with other colour housing options typically available subject to delivery lead time.

🧾 Features Common to All Four Levels

Across all technology levels, the Widex Evoke Power BTE FP series shares a robust core of essential technologies:

• Paraphrased: Every model in the Evoke FP range – from the flagship FP 440 down to the essential FP 110 – includes the full SoundSense machine‑learning personalisation capability.

• 2.4 GHz direct audio streaming – Stream phone calls, music, podcasts and videos directly from iOS and compatible Android devices. The FP series includes built‑in Bluetooth LE for both MFi and ASHA support. Two‑way audio calls are possible with compatible smartphones.

• TrueInput Technology – A linear input range of 113 dB SPL, preserving soft sounds without distortion while handling very loud sounds gracefully. A high input range is critical for hearing well in noisy environments and for a better music appreciation experience.

• Dynamic Feedback Controller – Fast, artefact‑free cancellation of whistling feedback, essential for power BTE devices where the microphone and receiver are in close proximity and high gain is required.

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

• ZEN / ZEN Plus tinnitus management – Soothing fractal‑tone therapy, built into all Evoke products, offering relief for users who experience ringing or buzzing in the ears.

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

• Programmable push button – Customisable for short or long presses to change programmes or adjust volume.

🚫 What Is NOT Included (Honest Disclosure)

The Widex Evoke Power BTE FP series does include the core features described above – but there are important caveats:

• No rechargeable battery – The FP series uses disposable size‑13 batteries only. There is no rechargeable lithium‑ion option for this Power BTE model (unlike some other Widex families such as Magnify BTE R D).

• Relies on audiologist setup – While the app allows extensive user control and SoundSense Learn personalisation, the initial fitting, gain settings, and programme configuration must be performed by your audiologist.

• Processing speed – The Evoke platform uses standard processing speeds; it does not include the ultra‑fast PureSound™ processing (<0.5 ms) found in newer Widex Moment models.

• Not fully automated AI – Smart learning requires you to use SoundSense Learn (in the app) to teach it your preferences. The hearing aid does not guess your preferences on its own.

The Evoke Power BTE FP series is designed for users with moderate to fairly severe hearing loss (20–110 dB HL) who require high‑gain BTE amplification, value the intelligence of live machine learning, and appreciate the convenience of an exceptionally long‑lasting disposable battery. It is the right choice when clinical need for power is the primary driver, but you still want the benefit of a personalised, learning hearing aid.

🧑‍⚕️ Who Is the Evoke Power BTE For?

The Widex Evoke Power BTE FP is best suited for users with moderate to moderately severe hearing loss (up to 110 dB HL) who:

• Need high power – The conventional earhook and custom earmold configuration delivers the gain required for more significant hearing losses where open‑fit RIC or standard BTE devices are insufficient.

• Want machine‑learning personalisation – You teach it your preferences through the app, and it improves over time automatically.

• Prefer disposable batteries – The size‑13 battery gives up to 18 days of use from a single cell – the longest battery life of any Widex device. No daily charging, no remembering to charge overnight.

• Value direct smartphone streaming – The 2.4 GHz FP series supports direct audio streaming from iOS and compatible Android devices, making it easy to take calls and enjoy media through your hearing aids.

• Need durability – The IP68 rating and robust BTE housing stand up to active lifestyles and outdoor conditions.

Which level should you choose?

• Choose the FP 440 if you want flagship performance: 15 channels, the highest number of sound classes, advanced fine‑grained directionality, maximum programme flexibility, and the best noise‑management capabilities – ideal for users who face complex, changing listening environments daily.

• Choose the FP 330 for advanced everyday intelligence: 12 channels, strong adaptability across varied environments, advanced directionality and noise management – excellent performance without the highest price.

• Choose the FP 220 for solid mid‑range value: 10 channels, core Evoke intelligence, effective speech‑in‑noise handling, and basic wind/impact noise management – perfect for quieter lifestyles or first‑time users.

• Choose the FP 110 for essential smart hearing: 6 channels, the full SoundSense Learn & Adapt experience, and core amplification features – still learns from you, still improves over time, and still delivers natural Widex sound, at the most accessible price.

If you do not need power BTE amplification (i.e. your hearing loss is less severe and can be managed with open‑fit RIC or smaller devices) or you require a rechargeable battery, consider the Widex Evoke Fusion 2 RIC rechargeable models instead. However, for power, machine learning, and the longest possible battery life from a disposable, the Evoke Power BTE FP series – from the affordable 110 up to the flagship 440 – remains an outstanding solution.
