Ultra-Light In-Ear Design

Weighing 3.8 grams each, these earbuds use an ergonomic shape tested on 1000 people to match the inner ear contour. The single-ear coupling and three included silicone tip sizes keep them secure during sport or all-day wear without protruding.

Bluetooth 5.3 Pairing

Bluetooth 5.3 provides a stable wireless link to iOS and Android devices. Opening the charging case triggers automatic connection between both buds, removing manual pairing steps. The 16-ohm impedance and 40-decibel sensitivity work directly with standard phone outputs.

Touch Control and Call Clarity

Smart touch panels let you manage playback and calls without pressing the buds into your ears. An AI-enhanced microphone algorithm isolates your voice for clearer conversations, while 4.5 hours of playtime and a one-hour charge cycle support daily use.

Questions about this item

How long does the battery last before the earbuds need recharging?

Each earbud provides up to 4.5 hours of continuous playback on a full charge.

Will the earbuds get hot or noisy during long listening sessions?

The 3.8 g in-ear design has no active cooling or moving parts, so they run silently and stay at body temperature.

What charging equipment do I need that isn't included?

A standard 5 V USB charger rated at 1 A is recommended; fast chargers are not required.
