⚡ At a Glance
- • Sound Signature: Open, airy presentation with clear mids and detailed highs
- • Best for: Active listeners who want music while staying aware of surroundings
- • Not ideal for: Users who need full passive noise isolation or closed-back sound
Large 12mm × 17mm racetrack drivers with a titanium-coated diaphragm deliver clear, open-ear sound. Clip-on form and attachable ear grips focus on stability and breathability rather than isolation.
All-day breathable comfort - with open-ear clip-on construction
Open-ear design keeps the ear canal unobstructed and the outer surfaces use breathable materials to reduce heat and pressure. The clip-on shape spreads contact over a larger area for less localised strain.
Comfort that lasts through long commutes or extended runs, keeping ears ventilated while music plays. Less ear fatigue compared with in-ear buds that seal the canal.
Secure fit for movement - thanks to non-deforming hard-shell and attachable ear grips
A firm-shell framework resists deformation over time, preserving the clip-on geometry, while supplemental ear grips attach where needed to lock position. The combination prevents slippage during dynamic activity.
Retention remains reliable during workouts and outdoor pursuits, so users can move confidently without constant readjustment. Clips and grips work together to keep the earphones stable.
Clear audio and long sessions - with large racetrack drivers and extended play time
12mm × 17mm racetrack drivers are paired with a titanium-coated diaphragm to improve transient response and detail in an open-ear layout. A long play time specification supports extended listening between charges.
Sound remains intelligible and balanced in a format that lets environmental sounds through, and long play time supports multi-hour outings without frequent recharging.
