Assessment scenario: Open-ear listening without a sealed canal tip
An editorial assessment scenario for a shopper considering an open-ear wearing style. This describes the wearing layout only; noise-control capabilities differ by exact model, and this is not a statement of the visitor's intent.
Explore this buying guide ↗Why consider this model?
- Bose identifies the Black second-generation Ultra Open as an open cuff design with no active noise cancellation; it leaves the canal unsealed.
- The 2026 announcement documents Bluetooth 5.4, SBC/AAC, two-device multipoint and aptX Adaptive on a compatible Snapdragon Sound source. Bose also lists USB-C and wireless charging for the Black case.
Tradeoffs to weigh
- This product does not meet an ANC need or provide a sealed passive barrier.
- Bose’s announcement and owner guide say nine hours of standard earbud time, while its current battery-help page says ten. The announcement says 19.5 case hours but the guide says 28.5 under its test conditions; no single standard or case-runtime number is selected. Feature-enabled earbud time drops to five or four hours in the owner guide.
- IPX4 applies to earbuds only; the case is not water resistant. Fit and ambient audibility are untested and personal.
- aptX Adaptive requires a compatible Snapdragon Sound source and is not combined here with the separately documented multipoint plan.
Check these before ordering
- Match the Black second-generation US SKU ULT2-HEADPHONEOPN-BLK-WW; distinguish it from first-generation Ultra Open and the 2026 Sport Open.
- Confirm the complete wireless case, USB-C cable and documentation; remember the case itself is not water resistant.
- Verify the Android source supports Snapdragon Sound before relying on aptX Adaptive; use seller return terms to check cuff comfort.
- If battery duration matters, select the published runtime for the feature setting you intend to use and reconcile the current official case-runtime discrepancy with Bose.
