Phonak Slim L70-R Hearing Aids Overview 

The Phonak Slim L70-R is an advanced-level hearing aid built on Phonak’s Lumity platform, offering clear sound, reduced background noise, and a stylish, modern design. Launched in May 2023, the Slim range is created to fit naturally behind the ear while complementing the contours of the head. This makes it especially comfortable for people who wear glasses or face masks.

The Slim L70-R combines performance and appearance, giving users a device that looks modern while delivering excellent everyday hearing support.

Key Features: Phonak Slim L70-R Hearing Aids

SmartSpeech™ Technology

SmartSpeech uses AutoSense OS 5.0 to automatically adjust your hearing aids in real time. It improves speech understanding, reduces background noise, and provides easier listening in both simple and challenging situations.

The Slim L70-R also works with Roger On, a portable microphone that helps users hear clearly in noisy places and group conversations. Roger On provides stereo sound and better sound direction awareness.

StereoZoom 2.0

This feature focuses on speech as surrounding noise increases and can improve the signal-to-noise ratio by up to 2.5 dB, helping you hear voices more clearly.
