Thunelec U9 Bluetooth 5.4 Earbuds 45dB ANC 48H Dark Black

Thunelec U9 Bluetooth 5.4 Earbuds

The Thunelec U9 are true wireless in-ear headphones built for commuters and office workers who want active noise cancellation and long battery life in a compact form. They use Bluetooth 5.4 for stable connections with iOS and Android devices. A multifunctional touch screen on the charging case adds direct control over playback and settings without reaching for a phone. This product is not for listeners who require over-ear comfort or dedicated high-resolution audio codecs beyond standard Bluetooth transmission.

45dB ANC with 48-hour total playback

Active noise cancellation reduces ambient sound by up to 45dB, cutting roughly 90% of low-frequency noise such as engine rumble and office chatter. Environmental noise cancellation sharpens voice pickup during calls. Each earbud runs for about six hours with ANC active, and the case extends total listening time to 48 hours. The case itself recharges fully in 1.5 hours. Buyers who need more than eight hours of continuous use per charge without the case should look elsewhere.

IPX7 waterproof with touch-screen case

An IPX7 rating means the earbuds survive immersion in water up to one metre, making them suitable for heavy sweat and rain. Three sizes of silicone tips (S/M/L) provide a secure, pressure-free seal for long sessions. The charging case features a built-in touch screen that displays battery status and lets you switch among five EQ presets (Standard, Classic, Jazz, Rock, Pop) or toggle transparency mode. Users who prefer physical buttons or a companion app for deep customisation will not find those options here.
