Questions about this item

Will the earbuds pair with a phone that only supports Bluetooth 5.3?

Yes, the headphones use Bluetooth 5.3 and support HSP, HFP, A2DP and AVRCP profiles for broad compatibility.

How can I confirm the active noise cancellation is actually reducing background sound?

Enable the ANC mode via touch control and listen for a noticeable drop in low-frequency ambient noise such as engine hum.

Does the box include a USB-C cable and ear tips, or must I buy them separately?

The package contains the earbuds, charging case with dual LED display and a Type-C charging cable; ear tips are pre-installed.
