Product Overview

Key advancements from its predecessor, the QCC Dongle Pro, include:

-
New support for LHDC 5.0, enabling bitrates of up to 990kbps.
-
Compatibility with LE Audio (LC3 codec) and Auracast™ broadcast standards.
LE Audio Compatibility Status
The QCC Dongle Pro 2 supports Bluetooth LE Audio and the audio broadcast standard Auracast™. However, as the LE Audio ecosystem is still in a transitional phase, implementation and support vary among manufacturers.
Questyle has confirmed compatibility with the following devices:
-
Qualcomm-based devices:
-
Questyle’s own products: SIGMA, SIGMA Pro, M18i, M18i Max
-
beyerdynamic AVENTHO 300
-
Creative ZEN
-
Bowers & Wilkins Pi8 / Pi6 (TWS) are expected to gain compatibility through future firmware updates.
Current Bose and B&O products are not yet compatible. Furthermore, due to the technical requirements for Snapdragon Sound certification, Questyle cannot guarantee compatibility with devices from non-Qualcomm chip brands such as Sony, Panasonic, and audio-technica, even if they feature LE Audio.
Questyle is committed to continuing real-device testing across various brands and will regularly update its compatibility list (whitelist). The latest information will be available on the product page and X (formerly Twitter).

The QCC Dongle Pro 2 will be available for purchase at major retailers, including e-earphone, Fujiya AVIC, Yodobashi Camera, and Bic Camera.
