Audio data moves 150 percent faster, yet range still depends on the source device and obstacles. The earbuds pair automatically when removed from the case and work with any Bluetooth-enabled phone, tablet or computer.

40-hour total playtime

Each bud runs for 8 hours on a single charge and the case extends listening to 40 hours. A full recharge via the Type-C port takes 1.5 hours. Dual LED indicators show remaining power for both buds and case. Buyers who need longer unbroken sessions or wireless charging should consider other models.
