Shokz's Innovative Achievements at IFA Berlin 2025

On September 6, 2025, Shokz, a cutting-edge manufacturer of headphones designed for continuous listening, proudly announced that its models, including the 'OpenFit 2 Series', 'OpenRun Pro 2', 'OpenRun Pro 2 Mini', and 'OpenDots ONE', have achieved the prestigious 'Comfortable Fit Certification' from TÜV Rheinland. This marks a historical milestone as these open-ear headphones are the first to garner this certification, which stands as a new industry benchmark for comfort in wearable audio products.

Background and Overview

In recent years, the instances where audio devices are worn for extended periods have surged, encompassing activities such as music listening, phone calls, fitness routines, and remote working. Open-ear headphones, designed to allow external sound while enhancing comfort, are gaining significant attention. However, the lack of clear and objective metrics to measure comfort has been a challenge in truly validating these products. The 'Comfortable Fit Certification' aims to address this gap by establishing a new standard for comfort through rigorous testing and exceptional design quality.

At the certification ceremony held during IFA Berlin 2025, notable figures were present, including Marc Zaplin, Vice President of the Electrical Division at TÜV Rheinland, and Thomas Zhang, Area Manager for DACH & Benelux at Shokz. They engaged in fruitful discussions highlighting the inclusivity of the certification as well as the future advancements anticipated in headphone technology.

Understanding the 'Comfortable Fit Certification'

The 'Comfortable Fit Certification' program involves a series of objective tests and human factor assessments concerning various comfort-related elements. Participants of diverse ear shapes and ages contribute to verifying the adaptability and user experience during extended wear in realistic scenarios.

Key Indicators of Comfort

- Weight Distribution and Total Weight: Ensures that the headphone design facilitates a balanced feel when worn.
- Wearing Pressure (Side Pressure and Contact Pressure): Assesses the pressure exerted on the ears during typical use, including various activities.
- Thermal Properties: Examines the temperature rise at the contact points during prolonged use to ensure no discomfort arises.
- Dynamic Stability: Evaluates how well the headphones stay secure during physical activities such as walking or light exercise.
- Subjective Feedback: Collects opinions on discomfort, fatigue, and overall comfort from users to create a comprehensive assessment of the product's performance.
