Key Performance Upgrades
Secure TwistLock™ Ear Hook Integration
The standout structural feature remains the flexible, bendable ear loop system. Utilizing an updated ergonomic TwistLock™ stabilization profile, the ear hook locks firmly yet comfortably behind your ear. This guarantees the earbuds will not shift or slide out during high-impact exercises like trail sprints, weight training, or cycling. Built-in sensor circuits automatically power the earbuds on the moment you clip them over your ears.
Flagship IP68 Water and Sweat Isolation
Engineered to survive rigorous outdoor training, the earbuds hold a definitive IP68 certified rating. The outer casing completely locks out fine sand, trail dust, and sweat. They are fully saltwater resistant and can withstand deep water submersion up to 1.5 meters for 30 minutes. This means you can comfortably push through heavy downpours or rinse the earbuds straight under a tap after grueling runs.
Enhanced Audio with Personi-Fi Optimization
Backed by dense 10mm dynamic drivers, the buds unleash bold, punchy JBL Pure Bass Sound paired with immersive JBL Spatial Sound. For the ultimate audio experience, the system supports advanced Personi-Fi optimization through the companion software. This digital feature scans your unique hearing profile to balance the thumping low-end perfectly with clear mid-ranges and crisp high-pitched frequencies.
