Google Pixel Buds 2a / Beats Studio Pro

A carrying case for the folded headphones is in the box.

Beats says distortion at high volume is up to 80% lower than on the Studio3 Wireless. The digital processor adjusts the frequency response for balance.

Pressure relief adjusts pressure in the ear canal to reduce the blocked feeling of a sealed in-ear design.

Adaptive ANC keeps adjusting the cancellation to the fit and surrounding noise. Transparency mode passes outside sounds such as announcements or traffic through the microphones.

Full features need an Android 6.0+ phone and a Google account; on iPhone basic listening works but app settings are unavailable.

Super wideband carries a wider audio range on calls with compatible Pixel phones.

Charging is via USB-C; no power adapter is included.

IP54 protects against dust and splashing water; the earbuds are not designed to be submerged.

Additional retailer-exclusive colours have also been sold.

Head tracking keeps sound anchored to the screen as you turn your head; this works with Apple devices.

On a USB-C cable the headphones act as a digital audio interface; the sound profiles are only selectable on this connection: Signature for music, Entertainment for films and games, Conversation for calls and podcasts. The 3.5 mm input is for analogue sources such as in-flight entertainment.

Class 1 Bluetooth uses higher transmit power for longer range and fewer dropouts. Beats says pairing on Apple spreads to every device on the iCloud account; on Android the Beats app adds settings.
