The Phonak Naída Lumity L70-PR is a high-performance, rechargeable behind-the-ear (BTE) hearing aid designed for people with moderate to severe hearing loss who want both power and advanced smart features. Built on Phonak’s Lumity platform and powered by SmartSpeech™ Technology, the L70-PR offers a seamless listening experience across a wide range of environments, while also delivering the convenience of direct connectivity and a reliable lithium-ion battery.

Intelligent Listening with SmartSpeech™ Technology

At the heart of the Naída Lumity L70-PR is Phonak SmartSpeech™ Technology, which runs on AutoSense OS 5.0. This system continuously analyzes your acoustic environment (whether you’re in a quiet room, a bustling cafe, or out on a windy street) and dynamically adjusts your hearing aid settings to optimize understanding and reduce listening effort. 

Some of the standout speech-enhancing features include:

• StereoZoom 2.0: A sophisticated adaptive directional microphone system that focuses on speech coming from different directions for better clarity in noisy groups
  
  
• Dynamic Noise Cancellation: Helps reduce background noise so conversations feel clearer.
  
  
• UltraZoom: Provides strong directional focus to pick up speech in very challenging listening situations.
  
  
• Motion Sensor Hearing: In the PR version, this sensor detects when you're moving and adapts the sound settings accordingly, making speech comprehension easier while walking or in motion.
  
  
• Tap Control: You can use a simple tap on the hearing aid to change settings, like switching programs or adjusting volume — very handy when streaming or changing environments.
  
  

Universal Connectivity

The L70-PR supports direct Bluetooth® streaming from both iPhone and Android devices, letting you stream calls, music, videos, and more directly into your hearing aids.
It also works with the myPhonak app, so you can personalize your programs, adjust volume, and monitor your battery usage in real time.
Moreover, you can pair it with Roger wireless microphones for challenging listening environments, giving you a further boost when you need it. 

Rechargeable & Reliable Power

The “PR” in L70-PR stands for built-in rechargeable, meaning you don’t need to worry about replacing disposable batteries. Instead, it uses a lithium-ion battery designed for all-day use. According to BuyHearingAid, you can get up to 30 hours of hearing per full charge.
Charging times:

• 0% to 100%: ~ 3 hours
  
  
• 0% to 80%: ~ 1.5 hours
  
  

Durable & Built to Last

• The hearing aid has an IP68 rating for dust and water resistance — it can handle immersion in 1 meter of freshwater for 60 minutes, making it robust in everyday life.
  
  
• It features a hydrophobic coating to resist moisture, adding another level of protection against sweat or humidity.
  
  
• With a built-in motion sensor and tap control, it’s designed for active users who need smart, durable performance.

Despite its power, the device is surprisingly lightweight — 3.68 g for the PR version.
