SERPENT XIAOXIU 2025 noise-cancelling sleep true-wireless earbuds in-ear, side-sleep friendly, pressure-free (hot new release)

HOLY SERPENT “Xiao-Xiu” Sleep Earbuds

Compact sleep-focused earbuds designed to stay comfortable and secure through the night. A shallow-insert shape with a soft stabilizing fin and 360° silicone wrap sits flush in the ear so side-sleeping won’t create pressure. Dual-mic ENC helps reduce steady background noise for calmer listening and clearer calls at low volume.

Features Description

• No-feel, side-sleep fit: shallow, canal-hugging profile with a soft fin provides a stable seal that stays put when you turn over.
• 360° soft-silicone wrap: cushioned contact all around the earbud helps minimize pressure points and improve long-wear comfort.
• Triple-comfort ear-tip design: soft contact layer, breathable mesh, and an isolation layer balance comfort, airflow, and passive noise blocking.
• Dual-layer diaphragm driver: TPU + PEEK composite diaphragm targets clear, balanced sound with good detail at low listening levels.
• ENC for clearer calls: dual microphones on left and right use environmental noise-cancelling processing to improve voice pickup.
• All-day endurance: up to 7 hours on a single charge and up to 21 hours with the case (typical lab values; actual time varies by volume and use).
• Reliable connection: Bluetooth 5.3 with quick pairing and stable performance for nightly use.
• Touch controls (eyes-closed friendly): one-finger gestures for volume, play/pause and track skip—easy to adjust without looking.
• Colorways: Ocean Blue, Gunmetal Black (availability may vary).
