An analysis of the app files for the “Google Pixel Buds” companion app (v1.0.915175631)—which supports the Pixel Buds (2nd Gen), Pixel Buds A-Series, Pixel Buds Pro, Pixel Buds Pro 2, and Pixel Buds 2a—released on Monday, June 1, 2026, confirmed that resource code related to a high-quality audio feature codenamed “Quartz” has been added.

<string name="key_feature_a">key_feature_a</string>
<string name="key_feature_a_dialog">key_feature_a_dialog</string>
<string name="title_feature_a_pref">Quartz</string>
<string name="summary_feature_a_pref">Improves sound quality when possible</string>
<string name="title_feature_a_dialog">Turn on Quartz?</string>
<string name="summary_feature_a_dialog">Quartz dialog warning</string>
<string name="title_feature_a_required_dialog">LE Audio required</string>
<string name="summary_feature_a_required_dialog">Quartz summary</string>
<string name="summary_multipoint_with_feature_a_enabled">Not available with Quartz on</string>
<string name="summary_sa_switch_with_feature_a_enable">Not available with Quartz ON</string>

The resource code confirms that this high-quality audio feature, codenamed “Quartz,” will utilize “Bluetooth LE Audio (LC3 codec).” It also appears that when using “Quartz,” features such as “Spatial Audio” and “Multipoint,” which allows connection to two devices simultaneously, will be disabled.

In other words, “Quartz” is a trade-off feature that improves sound quality at the cost of restricting certain other functionalities. However, no further details are known at this time.

Additionally, it is currently unclear whether “Quartz” will be compatible with all Pixel Buds series models or if it will be exclusive to higher-end models like the Pixel Buds Pro series.
