Bluedio H-Turbine Over-Ear Headphones — Wireless Bluetooth 5.0, 57mm Drivers, Powerful Bass, Built-in Microphone — Retail Package Global Release (Black)

Signature low-end impact: 57mm ultra-large dynamic drivers housed in a turbine-style shell deliver the iconic Bluedio bass punch while keeping mids and treble clear and detailed so you hear every layer of the music. Comfort and build: custom supra-aural soft earmuffs use artificial protein leather that mimics human skin texture to provide long-lasting comfort even in rugged conditions. Calls and clarity: Acoustic echo cancellation and noise reduction cut down background noise during conversations so the person on the other end won’t hear ambient sound — calls feel nearly face-to-face. Connectivity and battery: equipped with a high-speed CPU running a Bluetooth 4.1 operating system, the H-Turbine offers up to 40 hours of music playback, 45 hours of talk time and 1625 hours (approximately 67 days) standby; the same battery reduces power draw by up to 40% compared to Bluetooth 4.0. Sharing and multi-device use: Audio Sharing lets you link another H headphone via an audio cable to share audio instantly (recommended to use headphones with impedance of 32 or higher). The headset can also connect to two devices at once for seamless switching between phone and tablet. Wired option and voice prompts: plug in an audio cable (buy separately) to use the headphones without consuming battery power. H-turbine also incorporates 4 languages voice prompts (Chinese, English, French, Spanish) to guide operation.
