Broader Protocol Coverage
Adds LHDC, LE Audio and Auracast™ for flagship-level full-protocol support.
More Stable Connectivity
Bluetooth 6.1 improves interference resistance, stability, and latency sync in complex environments.
More Manageable Experience
Questyle App enables codec selection, firmware updates, device management, and real-time status display.
When QCC Dongle Pro2 is connected to an iPhone, iPad, or Mac, it adds professional high resolution Bluetooth transmission capability to Apple devices. It enables LDAC, aptX, LHDC and other high-quality wireless audio codecs, helping unlock the full performance of compatible headphones. Apple MFi certification also provides a reliable foundation for system compatibility, power management, and long-term iOS update support.
Many users already own LDAC-compatible premium headphones, but smartphones, computers, or consoles may not reliably output LDAC at up to 990kbps. As a result, headphone performance is underused.
With LDAC support, QCC Dongle Pro2 helps source devices output high-bitrate wireless audio more reliably, releasing the detail, resolution, and dynamics of premium headphones from Sony, Technics and more, and bringing wireless audio closer to a lossless experience.
Dongle Pro2 is optimized for PS5, Nintendo Switch, Steam Deck and Windows gaming, delivering low-latency audio for immersive gameplay with compatible Bluetooth headphones.
With Auracast™ and multi-device broadcasting support, you can also share movies, TV shows or music with multiple compatible Bluetooth devices, perfect for traveling, family entertainment or enjoying content together without disturbing others.
