The UGREEN HiTune H6 Pro (WS203) are true wireless earbuds designed for those who value high-fidelity sound in a portable format. They feature 13mm composite diaphragm drivers that support a wide frequency response from 20Hz to 40kHz, earning them the Hi-Res Audio certification and compatibility with LDAC, AAC, and SBC codecs for detailed audio playback. To keep you immersed in your music, these earbuds utilize adaptive active noise cancellation capable of reducing ambient sound by up to 43dB. Built from a blend of ABS and polycarbonate, the half-in-ear design provides a comfortable fit for long listening sessions while maintaining an IPX5 water resistance rating that protects against sweat and splashes. You can manage your audio through intuitive touch controls or experience a more immersive atmosphere with spatial sound. For calls, six microphones paired with an AI algorithm work together to ensure your voice remains clear by filtering out background noise. Connectivity is handled by Bluetooth v5.3 for a stable wireless link. Each earbud houses a 35mAh battery providing up to 6 hours of playback, while the 400mAh charging case extends the total listening time to 30 hours. The set charges via a USB Type-C cable in about 1.5 to 2 hours, making them a practical choice for daily commutes or gym workouts.
