Beltone uses a binaural connection to create a stronger, more focused beam for sounds in front of the listener. Compared to traditional directionality it provides a significant improvement for listening in noisy places like restaurants, bars, or family gatherings. The Serene and Achieve lines also utilize a steering system that can narrow the directional response while utilizing faster processing. Small but powerful – The Serene microRIE is Beltone’s smallest-ever rechargeable RIE hearing aid—25% smaller than its standard models—but still offers a full day of battery life. Hands-free phone calls and tap controls – With Beltone Serene you can take hands-free calls (for compatible phones) by simply double-tapping on the device or your ear. M&RIE – The “Microphone & Receiver-In-Ear” places a third microphone inside your ear canal for more natural sound pickup. Beltone says this technology improves sound localization, wind noise reduction, and sound quality ratings. High-bandwidth audio streaming – The extended bandwidth of the chip platforms in Serene, Achieve, and Imagine hearing aids provides high sound quality when streaming music or phone calls directly from Apple and Android devices, or with 2.4 GHz audio streamed through Beltone wireless accessories. Rechargeable batteries – Beltone touts the long life of its rechargeable lithium-ion battery options in Serene and Achieve hearing aids. The company says a single 3-hour charge provides 30 hours of power.
