Combining Hybrid Active Noise Cancellation with an extended 65-hour battery and Bluetooth 5.4, the Sudio K2 Pro represents a significant step forward from the standard K2. Built for users who demand more from their daily headphones — longer sessions, clearer calls, and tighter wireless connectivity — the K2 Pro delivers across all three without compromise.

Next-Gen Hybrid ANC

The K2 Pro's Hybrid ANC uses a combination of feed-forward and feedback technology, with built-in microphones detecting and analysing noise both outside and inside the ear cups. The system emits an inverted sound signal to neutralise incoming noise, resulting in highly effective reduction of environmental sounds across a broad frequency range.

Bluetooth 5.4 with AAC

An upgrade over the K2's Bluetooth 5.3, the K2 Pro connects via Bluetooth 5.4, offering improved connection stability and more efficient wireless performance. AAC codec support ensures high-quality audio transmission, keeping the sound clear and detailed regardless of signal conditions.

65-Hour Battery Life

The K2 Pro runs for up to 65 hours on a single charge without ANC, and up to 30 hours with ANC active — both figures exceeding those of the standard K2. A full recharge via USB-C takes approximately 150 minutes, making the K2 Pro well-suited for frequent travellers and demanding daily schedules.

Audio Performance

The sound profile spans a frequency range of 20 Hz to 20 kHz, delivering smooth and resonant bass, warm midrange tones, and clear high-frequency detail. The targeted ANC system works alongside the acoustic tuning to ensure ambient noise reduction does not come at the expense of audio fidelity.

Five-Microphone Array

Five microphones integrated into the K2 Pro handle call quality and ANC input simultaneously, capturing the user's voice with precision while filtering background interference. Call clarity remains strong in busy urban environments, open offices, and during outdoor use.

Design and Portability

The K2 Pro features rotating ear cups that fold flat for compact storage and transport. Soft leather ear cushions and a lightweight over-ear construction keep extended wearing sessions comfortable, while a 3.5 mm audio input provides a wired fallback option when battery life is not available.
