One of the nicest upgrades in the 2nd Gen? The case finally supports wireless charging. Just drop it on any Qi charger and walk away.
Any wireless charging pad you probably already own will workβAnker, Belkin, Samsung, whatever's on your desk. Place the QuietComfort Ultra Earbuds 2nd Gen case with the LED facing up, and you're set.
The case still has USB-C if you prefer wired charging or need a faster top-up. Bose includes a short USB-A to USB-C cable in the box.
Here's the tradeoff with wireless convenience: it's a bit slower.
Not a huge deal if you leave it on a charger overnight, but worth knowing if you're in a rush.
Need juice fast? Twenty minutes in the case gives you about 2 hours of listening time. Perfect for those "running out the door" moments.
Your earbuds alone get about 6 hours (or 4 hours with Immersive Audio). The case holds enough power for 3-4 complete recharges, putting your total at around 24 hours before everything needs a plug.
If you have the 1st Gen, your case can't be upgraded to wireless charging. It's a hardware feature specific to the 2nd Gen case.
