True Wireless Earbuds for Active Use

The No Sew T8 are Bluetooth 5.4 in-ear headphones built for sport and daily travel. They weigh 35 grams and use liquid-silicone tips with a 45-degree tilt to stay secure during running or gym sessions. An IPX8 rating means they withstand heavy sweat and rain without damage. Four built-in ENC microphones filter background noise so calls stay clear in busy environments.

Case and Connection Essentials

The charging case connects via USB-C and holds enough power for 70 hours of total playback. A 15-minute top-up adds 2 hours of listening when time is short. LED indicators on the case show remaining charge for both buds and case at a glance. Bluetooth 5.4 handles the wireless link to Android and iOS devices without a cable or jack. The single-ear coupling option lets you use one bud while the other charges.

Sustained Listening Behaviour

Each bud delivers 14 hours of continuous play on a full charge before needing the case. The 14.2-millimetre drivers produce a 5Hz to 20KHz frequency response with 108-decibel sensitivity and 32-ohm impedance. Passive isolation blocks ambient sound during long commutes or extended work sessions. Recharge time for the buds is 1.5 hours, so a short break restores a full day of audio.
