en.Wedoany.com Reported - China's Questyle Audio has recently launched the QCC Dongle Pro2 flagship Bluetooth transmitter, which is powered by the second-generation Qualcomm S5 Audio Platform and supports Snapdragon Sound technology, as well as high-quality audio codecs including aptX, aptX HD, aptX Adaptive, and aptX Lossless, along with Bluetooth 6.1. This device aims to deliver a near-professional audio experience for users across different ecosystem devices through lossless audio transmission, stable wireless connectivity, and low-latency performance.
In terms of sound quality, the QCC Dongle Pro2 supports Snapdragon Sound technology and Qualcomm aptX Lossless audio technology, enabling 24-bit/48 kHz high-definition lossless audio transmission. This provides more precise sound detail reproduction, bringing wireless listening closer to the depth and dynamics of wired Hi-Fi.
Regarding connection stability, the product leverages Snapdragon Sound technology and Bluetooth 6.1 support to reduce audio interruptions or interference in complex RF environments, making it suitable for mobile work, commuting, and multi-device home settings.
For gaming scenarios, the QCC Dongle Pro2 expands wireless audio capabilities for handheld consoles and gaming devices, and allows non-Snapdragon Sound audio source devices to enjoy low-latency, high-quality wireless audio experiences. When paired with Snapdragon Sound headphones, audio transmission latency can be reduced to as low as 48ms, providing swift sound response and game feedback. Additionally, the product supports future Bluetooth Low Energy Audio (LE Audio) technology, which can further reduce audio latency when the receiving end is compatible, enhancing audio-video synchronization.
The QCC Dongle Pro2 also supports Auracast audio broadcasting based on LE Audio, breaking away from the traditional one-to-one connection model to enable synchronous broadcasting from a single audio source to multiple compatible devices. This is suitable for home audio sharing, group movie watching, conference presentations, exhibition displays, museum tours, and public venues such as airports and cinemas, driving wireless audio from personal listening to multi-user sharing.
Building on the previous generation, the QCC Dongle Pro2 is upgraded for the next-generation Bluetooth audio ecosystem, connecting to terminals such as smartphones, tablets, PCs, and gaming handhelds via a plug-and-play design. The accompanying app visualizes Bluetooth connections, allowing users to view connection status in real time and adjust audio parameters and manage connection modes based on scenarios.
Questyle Audio has collaborated with Qualcomm for many years to jointly drive innovation in wireless audio technology. The QCC Dongle Pro2, leveraging the second-generation Qualcomm S5 Audio Platform, Snapdragon Sound technology, and next-generation wireless audio features, achieves comprehensive upgrades in sound quality, latency, connection stability, and scenario expansion capabilities.
