Product Features

Adaptive Hybrid Active Noise Cancellation

The HiTune H6 Pro employs hybrid ANC technology that dynamically adapts to surrounding noise, effectively reducing ambient sounds. Combined with dual-microphone ENC and wind noise suppression, it ensures clearer voice calls in noisy environments.

High-Fidelity Audio with Large Dynamic Drivers

Equipped with 13mm dynamic drivers and support for LDAC, AAC, and SBC codecs, these earbuds deliver detailed, high-resolution sound with rich bass and clear treble. The semi-open design enhances the soundstage for an immersive audio experience.

Ultra-Low Latency for Gaming and Video

Bluetooth 5.3 connectivity provides a stable and low-latency connection. With an ultra-low latency mode of approximately 0.08 seconds (80ms), the earbuds are ideal for gaming, video streaming, and real-time applications.

Long Battery Life with Fast Charging

The earbuds offer 6–8 hours of playback on a single charge, depending on ANC usage, and up to 26–30 hours total with the charging case. USB-C fast charging allows the earbuds to charge in approximately 1.5 hours and the case in 2 hours.

Ergonomic and Durable Design

The semi-open, in-ear design provides a secure and comfortable fit for extended wear. Rated IPX5, the earbuds are resistant to sweat and light rain, making them suitable for workouts and outdoor activities.

Smart Connectivity and Controls

Supports dual-device connection, allowing simultaneous pairing with a phone and a laptop. Touch controls, in-ear detection for auto play/pause, and voice assistant support enhance usability, while the UGREEN App allows EQ adjustments and ANC mode customization.
