Human Factors UX Research Revolutionized Earbud Design for a Global Wearables Leader
Client Background
A Global Fortune 500 leader in consumer wearables (smartwatches, fitness trackers, audio devices) aiming to dominate the $50B market but struggling with design limitations.
Challenges Faced
This section outlines the core difficulties and pain points the client was experiencing. It provides context on the hurdles that needed to be overcome before achieving the successful outcome.
Anatomical Diversity:
Generic designs caused discomfort for 40%+ users due to varying ear shapes.
High Return Rates:
15% of returns due to fit issues, hurting profitability and brand reputation.
Activity-Specific Demands:
One-size-fits-all approach failed during workouts, calls, and commutes.
Exclusionary Models:
Narrow anthropometric data alienated diverse demographics.
