## Product: Bose QuietComfort Ultra Wireless Noise Cancelling Earbuds (2nd Gen, Black)

Planning your listening time with the [QuietComfort Ultra Earbuds 2nd Gen](https://shopsavvy.com/products/b595a4c3-458b-de58-b64e-402801d1cd84)? Here's the full picture on charging and battery life.

## The Quick Answer

Your earbuds get about 6 hours of playtime (4 with Immersive Audio). The case holds another 18 hours worth of charges, giving you roughly 24 hours total before everything needs a plug.

## Charging Speeds

**Earbuds in the case:**
About an hour from dead to full. But here's the useful bit—just 20 minutes gives you 2 hours of listening. Perfect for when you're running out the door.

**The case itself:**
- USB-C wired: About 2 hours
- Wireless charging: About 3 hours

Wireless is convenient, but wired is faster when you need it.

## What the Lights Mean

The LED on the case tells you what's happening:
- **Glowing amber:** Charging
- **Green:** Done
- **Blinking amber:** Case battery is low

When you open the case with earbuds inside:
- **Solid white:** Earbuds are charged
- **Pulsing white:** Earbuds are still charging

## Making Your Battery Last Longer

A few practical tips:
- Immersive Audio cuts battery from 6 hours to 4. Turn it off when you don't need it.
- Keep earbuds in the case when not using them—they stay charged and ready.
- Wipe charging contacts occasionally. Dirty contacts = slow or no charging.

## Real-World Battery Life

Bose says 6 hours, and testing usually shows around 5.5 hours in practice. That's normal—volume level and features used affect it. Most people find it's plenty for a workday or long flight.
