Questions & Answers

Q: What are the main features added with the Bose QC Ultra firmware 4.0.2 update?

The firmware update primarily focuses on adding multipoint pairing capabilities for connecting multiple devices simultaneously, offering improved general stability, and correcting various bugs. However, it does not address existing sound issues like the buzzing noise in the left earbud, which was anticipated by users before the update.

Q: How does the multipoint pairing functionality work with the new firmware?

Multipoint pairing allows users to connect the Bose QC Ultra to more than one device simultaneously. To switch devices, users must pause playback on the primary device to start playback on the second one. Although this feature is useful, it only indicates connected devices through audio prompts without allowing direct control from the earbuds.

Q: Did the firmware update change the noise-canceling performance of the Bose QC Ultra?

The noise-canceling capability of the Bose QC Ultra remains strong post-update, maintaining its position as one of the best on the market. However, a slight inconsistency was noted during the transition between transparency and noise-cancellation modes, with disparities in responsiveness between the left and right earbuds.

Q: Were there any significant changes in sound quality reported after the update?

After testing the sound quality post-update, there were minor changes detected in frequency response. Specifically, the sub-bass below 30 Hz was slightly reduced, while frequencies above 16 kHz might seem airier. However, many of these effects were subtle and unlikely to be noticed by typical users.

Q: Are there any new issues with Bluetooth connectivity after the update?

Yes, while the update improved connectivity with most devices, users reported persistent connection issues with PCs. Users experienced significant intermittent signal drops, prompting a recommendation to avoid updating if they primarily use their earbuds with a computer.

Q: How did the update affect microphone quality during calls?

The microphone quality and performance during calls remain largely unchanged, with no improvements in voice pickup or noise gating. Users can expect similar performance as before, continuing to find the QC Ultra effective for calls, but not significantly enhanced through the latest firmware.

Q: Is it worth updating to firmware 4.0.2 if users experienced issues with version 1.78?

The update can be beneficial for those who prioritize multipoint pairing and general stability improvements but may not be suitable for users reliant on consistent performance with PCs due to new connection problems. It's advised to stay updated on future patches that may rectify current issues.

Q: What should users do if they rely on the Bose QC Ultra for PC use?

Users who rely on their Bose QC Ultra for audio on PC should withhold the firmware update until further notice, especially given the reported connection issues. Following future updates may provide fixes that restore stable connectivity for PC audio.

Summary & Key Takeaways

• The new firmware 4.0.2 for Bose QC Ultra introduces multipoint pairing and enhances general stability but fails to fix the buzzing sound in the left earbud.

• Users are required to pause one connected device to switch to another, and while cycling through devices is possible, it lacks practical utility for playback.

• The update generally maintains sound quality, with subtle changes noted in noise cancellation and mid-range clarity, but also introduces new connection issues specifically with PCs.
