Due to Apple’s closed ecosystem and proprietary audio standards, its devices only support AAC and SBC codec formats, making them incompatible with Sony’s LDAC technology. As a result, when users attempt to connect LDAC-enabled devices to Apple products, the system cannot activate LDAC encoding, preventing access to the high-resolution audio LDAC provides.
As an official LDAC partner, Queshi Audio is dedicated to delivering a superior listening experience. The QCC Dongle Pro supports Sony’s LDAC at up to 990kbps, enabling near-lossless audio transmission and faithful reproduction of musical detail.
With plug-and-play simplicity, the QCC Dongle Pro allows users to connect directly to Apple devices—such as iPhone, iPad, or Mac—and pair with LDAC-compatible headphones or DACs to enjoy high-quality wireless sound with minimal setup.
The QCC Dongle and QCC Dongle Pro are the world’s first lossless Bluetooth transmitters to receive official Apple MFi certification. This certification ensures seamless compatibility with iPhone, iPad, and the broader Apple ecosystem, meeting Apple’s strict standards for power efficiency, device safety, and system integration.
Unlike uncertified USB accessories, the QCC Dongle series minimizes the risk of device or system issues, delivering a safer, more reliable experience. Even as iOS updates roll out, both dongles maintain stable performance, offering users long-term peace of mind and effortless connectivity.
QCC Dongle & QCC Dongle Pro are equipped with Qualcomm's latest generation Snapdragon Sound™ technology. With the ultra-high transmission speed and stability of Bluetooth 5.4, it ensures lossless sound quality and extremely low latency. It supports aptX, aptXHD, and aptXAdaptive codec technologies to bring a high-quality audio experience.
Questyle Audio Laboratory has optimized the QCC Dongle and QCC Dongle Pro for broad compatibility, addressing common issues like weak Bluetooth performance, unstable connections, and frequent dropouts. Whether you’re using a phone, tablet, or computer—on iOS, Android 5.1+, Windows, or macOS—the devices pair quickly and maintain a stable connection.
Recognizing that many laptops either lack Bluetooth or use outdated versions, Questyle has specifically enhanced performance for notebook users. The QCC Dongle series upgrades basic Bluetooth functionality from SBC to lossless transmission, dramatically improving wireless audio quality and convenience for both music and video. On Windows 10 (version 1803 and above) and macOS, no drivers are needed, just plug and play for a high-quality wireless experience.
The QCC Dongle and QCC Dongle Pro effectively overcome the Bluetooth audio limitations of the PS5 and Nintendo Switch, unlocking true wireless freedom for gamers. Since the PS5 does not natively support high-quality Bluetooth audio, achieving a seamless wireless experience has traditionally been difficult.
By supporting aptX Adaptive, QCC Dongle and QCC Dongle Pro deliver a low-latency, high-quality wireless connection that ensures precise audio-visual synchronization, letting you clearly hear every detail and react in real time. In addition to ultra-low latency, both dongles support high-definition voice transmission for headset microphones, enabling smooth, lag-free communication with teammates and enhancing your competitive edge online.
