More info

Phonak Bolero B is the comprehensive BTE portfolio for mild to profound hearing losses. Phonak Bolero B includes four designs and four performance levels, including a rechargeable BTE with the full feature set including a telecoil and volume control. Powered by the innovative technology of the Phonak Belong™ platform, Phonak Bolero B hearing aids are the ideal solution for those clients that prefer best hearing performance in a robust, water-resistant BTE housing.


  • UltraZoom: Directional microphone technology is a proven method of effectively improving speech intelligibility in background noise. UltraZoom is the adaptive multi-channel beamforming technology, automatically available in AutoSense OS or in a manual program.
  • DuoPhone: As soon as the phone is held to the ear, the caller's voice is automatically streamed to the other ear. Hearing the conversation in both ears results in superior sound quality and improved understanding.
  • FlexControl: FlexControl allows the wearer to easily make targeted adjustments that have a significant impact on satisfaction. It personalizes AutoSense OS, transforming the simple action of turning a control up or down into a powerful adjustment tool.
  • FlexVolume: FlexVolume brings additional sophistication to loudness adjustments. Instead of linear up and down shifts in gain, FlexVolume shapes the gain curve in a frequency dependent manner. This approach results in increased clarity when more volume is required, while comfort is enhanced with less volume.
  • Rear Ear Sound: When microphones are placed outside the pinna, natural front/back and vertical localization cues can be lost. Real Ear Sound, simulates the performance characteristics of the pinna. The result is restored localization and the ability to experience natural sound perception.
  • SoundRecover2: The next generation of SoundRecover further improves speech audibility and utilizes an adaptive frequency lowering algorithm. The sound quality of mid and low frequencies are maintained while high-frequency sounds  are made audible. This creates an optimal listening experience for more users than ever before.
  • Tinnitus Balance Noise Generator: The Tinnitus Balance noise generator generates a broadband sound for use in tinnitus management therapies, either in the context of masking or sound therapy such as Tinnitus Retraining Therapy. It offers fitting flexibility through the Phonak Target™ software.
  • WaterResistant: Phonak WaterResistant hearing aids are water, sweat, moisture and dust resistant.
  • WhistleBlock: WhistleBlock differentiates between naturally occurring feedback-like sounds and true feedback. This means increased audibility and sound quality that is free from annoying feedback.
  • NoiseBlock: Noise Block Processing is particularly effective at reducing uncomfortable environmental noise. It recognizes the subtle differences between speech and non-speech sounds, removing noise while maintaining audibility.
  • QuickSync: One-touch controls two. The instantaneous broadband transfer of data between two instruments ensures that volume and program settings are always balanced and synchronized. One touch on the program selection button or volume control results in instant identical change in the other instrument.
  • User Preference Tuning: Remembers adjustments you make with FlexControl and FlexVolume and applies them automatically for a hearing aid more in tune with your preferences.
  • Auto Acclimatization: Auto Acclimatization is used to automatically increase the client's amplification, while the client is using the device. The starting level, speed of the acclimatization and the target level can easily be adjusted.
  • AOV: A proprietary, multidimensional-weighted algorithm sets an ideal target "acoustic mass" for each vent. The sophisticated 3D modeling software generates an individualized vent. This unique Acoustically Optimized Venting (AOV) value is coded into each instrument and used to optimize the fitting calculation. Occlusion can now be reduced to the lowest level possible. This exclusive, clinically proven Phonak innovation is available in the full range of custom products and styles. It is also available for BTE wearers with a SlimTip, SlimTip Soft, cShell, or xShell.
  • Finetuning Channels: Precision by which clients' hearing aid can be customized to their specific hearing needs.
