    Description

    1. Equipped with high-efficiency batteries for ultra-long battery life, meeting all-day usage needs.
    2. Features a 13mm high-dynamic moving coil driver, delivering vinyl-grade sound quality with rich bass, an expansive soundstage, and highly restored vivid audio.
    3. Supports ANC active noise cancellation, which accurately cancels out ambient noise by generating anti-phase sound waves, creating a quiet private space.
    4. Equipped with ENC call noise reduction algorithm and dual high-definition microphones, intelligently separating human voice from background noise and reducing wind noise for crystal-clear calls.
    5. Convenient magnetic switch control: Earphones automatically power on and connect to paired devices when separated, and power off when attached together, eliminating button operations for easy use and storage.
    6. Adopts Bluetooth 5.4 technology for enhanced signal penetration, reduced sound loss and latency; paired with a ceramic anti-interference antenna for stable connection in complex environments.
    7. Supports e-sports game mode with dual-channel low-latency transmission, as low as 0.05 seconds latency for smoother audio-visual synchronization.
    8. Waterproof coating + waterproof mesh design provides IP-rated water and sweat resistance, making it worry-free for sports use.
    9. Neckband design fits comfortably around the neck and stays securely in place during running and other sports activities.

    Must Read before ordering. Where trust drives commerce

    We believe in honesty over marketing.
    Some items may not have customer reviews yet, but the reviews you do see are 100% authentic, verified, and managed by Judge.me, an independent review partner trusted worldwide.

    Instead of posting fake reviews, we prefer to show only what is real — even if that means some products are still waiting for their first review.
