NShi TWS Earbuds Bluetooth 5.1 IPX7 Black

TWS Earbuds with IPX7 Waterproofing

The NShi true wireless earbuds use Bluetooth 5.1 for stable connections with iOS and Android devices. An in-ear design with ABS construction provides a secure fit during exercise or daily commuting. Built-in microphones support hands-free calls and voice-assistant access. The IPX7 rating protects the buds against heavy sweat and temporary immersion.

Sustained Listening and Call Performance

The charging case replenishes the earbuds so playback continues across multiple sessions without plugging in. Bluetooth 5.1 maintains a consistent link during long meetings or workouts, reducing dropouts caused by interference. Sensitivity of 100±3 dB and 17 Ω impedance keep volume levels steady over extended use. One-step pairing reconnects instantly each time the case is opened.

Bluetooth 5.1 Practical Limits

Range and stability depend on the source device antenna and surrounding radio traffic. The IPX7 seal covers the earbuds only; the charging case is not waterproof. Audio codec support follows the host device implementation of Bluetooth 5.1. Buyers who need active noise cancellation, multipoint pairing or a higher water-resistance rating should consider other models.
