Which is better for running and workouts?

The Ultra. It is rated IPX4 for sweat and water splashes, and reviewers say it stays sealed during runs. The standard QuietComfort Earbuds has no water-resistance rating.

Is the Ultra worth the extra money?

If both sit near $229, the Ultra adds Immersive Audio, CustomTune, aptX Adaptive and IPX4 for the same money. If the standard model is meaningfully cheaper, it still delivers Bose noise cancellation.

Which has longer battery life?

They are close. Both give up to 6 hours per charge and about 18 hours with the case. The Ultra drops to 4 hours when Immersive Audio is on.

Does the standard QuietComfort Earbuds have spatial audio?

No. Immersive Audio is an Ultra feature. The standard model offers Quiet and Aware modes only.

Which is better for phone calls?

The Ultra. It has four microphones in each earbud and noise filtering for voice pickup. The standard model uses a beamforming microphone array.

Do both work with iPhone and Android?

Yes. Both use Bluetooth and support SBC and AAC, which covers iPhone and most Android phones. Only the Ultra adds aptX Adaptive for compatible Android devices.

Bose QuietComfort Earbuds (2nd Gen) vs Bose QuietComfort Ultra Earbuds (2nd Gen)

These are two different products despite the shared Bose name. The QuietComfort Earbuds (2nd Gen) is the older in-ear model with strong noise cancellation and a lower typical price; the QuietComfort Ultra Earbuds (2nd Gen) adds Immersive Audio, CustomTune, aptX Adaptive and IPX4 water resistance. The Ultra's lowest recent price was $229.00 on October 30, 2026, and its highest was $304.00 on November 4, 2026. Buy the Ultra if spatial audio and a sport-ready fit matter; buy the standard QuietComfort Earbuds if you want Bose noise cancellation for less.
