Commuters wanting long battery life

Buyers who need active noise cancellation or a higher water-resistance rating should consider other models. The IPX5 rating protects against sweat and light rain but not submersion. Anyone requiring a wireless charging case will not find that feature here.

Type-C charging case with LED power display

The case charges via a Type-C port in about two hours and can recharge the earbuds roughly three times. Each earbud holds a 40 mAh cell for up to six hours of music or four hours of talk time. The case itself stores 320 mAh to deliver the combined 30-hour figure.
