Bluetooth 6.1 — Stable Connection in Complex Environments
Upgraded from BT 5.4 on the original Pro, the Pro2's Bluetooth 6.1 delivers stronger anti-interference in crowded wireless environments, effectively reducing stuttering and disconnections. It also enhances privacy protection and power efficiency, while inheriting centimeter-level positioning for a more comprehensive next-gen wireless audio experience.
Full Flagship Codec Coverage — LDAC, LHDC V5, LE Audio, aptX Adaptive
The Pro2 supports every major high-resolution Bluetooth codec: LDAC at stable 990kbps, LHDC V5 for rich detail and expanded soundstage, aptX Adaptive for dynamic bitrate optimization, and LE Audio for forward-looking compatibility with the next generation of Bluetooth audio devices.
Auracast™ — One-to-Many Audio Broadcasting
The Pro2 supports Auracast™ broadcast audio technology, enabling one-to-many wireless sharing for multi-person home listening, office broadcasting, museum/airport public audio, and hearing aid connectivity. Note: Auracast™ requires both transmitter and receiver support — confirm compatibility with your headphones before use.
iPhone HD Audio Upgrade — Apple MFi Certified
iPhone natively supports only AAC and SBC. The Pro2 is Apple MFi certified, adding professional-grade HD Bluetooth transmission to iPhone, iPad, and Mac — enabling LDAC, aptX, and LHDC output to unlock the full potential of your high-end wireless headphones on Apple devices.
Low-Latency Gaming — Switch, PS5 & Handheld
Supporting aptX Adaptive (as low as 48ms) and LE Audio low-latency mode (as low as 20ms with compatible Qualcomm Gen2 receivers), the Pro2 brings wireless gaming audio closer to the wired experience with minimal audio-visual lag on Switch, PS5, and handheld consoles.
