Why a Bluetooth transmitter makes sense at all
Anyone with good wireless headphones knows the basic problem: the source can’t keep up with what the headphones are capable of. Even the latest iPhones only support SBC and AAC; PC Bluetooth quality varies from chip to chip; and consoles often lack the low-latency codec needed for lip-synced audio. This is exactly where the QCC Dongle Pro2 comes in: You plug it into the USB-C port, pair your headphones, and—depending on the receiver—get a higher-quality codec than the platform itself offers. Important to note: Whether LDAC, Auracast, or LE Audio is actually available depends on whether your wireless headphones support the respective standard.
Bluetooth 6.1: More Stable and Energy-Efficient
The centerpiece of the update is Bluetooth 6.1. Questyle promises, above all, greater stability in crowded wireless environments, a better connection, and more precise synchronization—the latter being the key factor when gaming. To put this in context: The official Bluetooth 6.1 standard (adopted in May 2025) primarily introduces more efficient address randomization for greater privacy and lower power consumption. The noticeable benefits in terms of latency and stability in everyday use therefore depend heavily on the implementation and the device on the other end.
The QCC Dongle Pro2 supports these codecs
Questyle is stepping up its game when it comes to codecs. In addition to the already broad range of aptX HD, aptX Adaptive, aptX Lossless, and Sony LDAC, LHDC-V5 and LC3 (LE Audio) have now been added. This means the dongle covers both the Qualcomm and LHDC ecosystems. Snapdragon Sound and LDAC certification are also included.

Auracast, MFi, and App Control
Auracast is a great feature for groups: Using this broadcast standard, an audio signal can be sent simultaneously from one source to multiple compatible receivers—handy at home, in the office, or in public places. Apple MFi certification ensures seamless integration with iPhone, iPad, and Mac, including efficient power management. Everything is managed via the Questyle app: keep track of paired devices, switch codecs, and install firmware updates. If you’d rather use the dongle as a classic Bluetooth bridge for your audio system, you’ll also find the right format among the many codecs available.
Price and Availability
The QCC Dongle Pro2 costs $99 and is available at questyleshop.com and on Amazon. Questyle has not yet announced an official price in euros for Germany; based on past experience, the price after taxes is typically slightly higher than the U.S. price. You can check current deals on Amazon. If you’re a fan of headphones with LDAC, this is where you’ll get the most out of them.
Frequently Asked Questions About the Questyle QCC Dongle Pro2
Does the QCC Dongle Pro2 work with the iPhone?
Yes. The dongle is Apple MFi-certified and connects via USB-C. It bypasses the limitation of current iPhones to SBC and AAC, enabling higher-quality codecs—provided the headphones support them.
Is the dongle suitable for gaming on the PS5?
That’s one of its intended uses. Thanks to Bluetooth 6.1 and low-latency codecs, the audio should remain as synchronized with the video as possible. Actual latency depends on the receiver and the wireless environment.
What’s the difference between this and the QCC Dongle Pro?
The Pro2 uses Bluetooth 6.1 instead of 5.4 and adds support for the LHDC-V5 and LC3 (LE Audio) codecs, as well as Auracast for multi-device streaming.
Conclusion
The QCC Dongle Pro2 does what made its predecessor interesting, only on a more comprehensive level: it brings high-quality wireless audio to devices that don’t support it natively. The upgrade to Bluetooth 6.1 plus LHDC, LC3, and Auracast is a sensible improvement, even if you should take the bold promises regarding latency and stability with a grain of salt when considering the receiving end. At the unchanged price of $99, it remains a clever tool for anyone who wants to get better sound out of their Bluetooth headphones on an iPhone, PC, or console—without cable clutter and without getting lost in the codec jungle.
