The Bose QuietComfort Ultra Earbuds 2nd Gen brings meaningful improvements over the original model. Here's what changed:
Major Upgrades
New Features
Unchanged
Should You Upgrade?
If you're happy with the 1st Gen, the upgrade isn't essential. If wireless charging and better call quality matter to you, the 2nd Gen delivers. First-time buyers should go with the 2nd Gen.
The Bose QuietComfort Ultra Earbuds 2nd Gen can handle workouts, though they're not designed as dedicated sports earbuds.
Water Resistance
IPX4 rating protects against sweat and light rain. Adequate for gym use but avoid submersion or heavy rain.
Fit System
Nine combinations of ear tips (S/M/L) and stability bands (1/2/3) provide secure fit for most users. Note: the earbuds are chunky and may not suit smaller ears.
Running Considerations
Some users report subtle "thunking" sounds from footsteps, especially when sweating affects the seal.
Safety Features
The Bottom Line
Excellent for casual workouts where audio quality is the priority. Serious runners or heavy gym users may prefer sports-focused alternatives with higher water resistance.
Connecting your Bose QuietComfort Ultra Earbuds 2nd Gen takes about a minute.
Enter Pairing Mode
iPhone Connection Settings → Bluetooth → Select "QuietComfort Ultra Earbuds"
Android Connection (Recommended)
Android Without App Settings → Connected Devices → Bluetooth → Pair new device
Fast Pair (Android) Many Android devices show automatic pairing notification. Just tap to connect.
Multipoint Connectivity Connect to two devices simultaneously. Pair your phone first, then repeat with a second device.
Troubleshooting
Bose Immersive Audio creates a speaker-like listening experience through earbuds, making sound feel like it's coming from in front of you rather than inside your head.
How It Works
Uses onboard sensors and Bose processing to create spatial audio. Unlike competitors, it works with any stereo source—no special content required.

Battery Impact
Reduces battery life from 6 hours to approximately 4 hours.
The Verdict
Worth trying. Easy to toggle on/off via earbuds or Bose app. Many users love it; others use it selectively. It's a key differentiator of the QuietComfort Ultra lineup.
The Bose QuietComfort Ultra Earbuds 2nd Gen significantly improve call quality over the first generation with new AI SpeechClarity technology.

Real-World Performance
Self-Voice Monitoring
Hear yourself naturally during calls. Adjustable in Bose app.
Important: Fit Matters
Improperly positioned stability bands can block microphones. Ensure proper fit for best call quality.
Comparison
Good but not best-in-class. AirPods Pro 2/3 still lead for call quality.
Verdict
Excellent for regular business calls and video conferencing. Power users who prioritize calls should consider AirPods Pro or dedicated headsets.
The Bose QuietComfort Ultra Earbuds 2nd Gen offer sound customization through the Bose app, though options are more limited than some competitors.
