Why this model
-
Swappable magnetic batteries — each earbud runs a 40 mAh cell that lifts out and clicks back in seconds; two 40 mAh magnetic spares are included so you swap instead of waiting to charge
-
Open-ear ear-hook fit — the hook rotates through 90° to sit the 10 mm driver over the canal without sealing it, keeping traffic, announcements and conversation audible
-
LED digital battery display built into the charging case — level readable at a glance; the 600 mAh case recharges the pair about twice and refills over Type-C in ~150 min
