Open-Ear Comfort

The Soundcore V20i uses an open-ear design that rests outside the ear canal for all-day wear without pressure. Four adjustable positions let each user rotate the hook to find a secure, stable fit. The earbuds weigh 76.4 grams total and carry an IP55 rating with SweatGuard protection against moisture.

Wireless Integration

Bluetooth 5.4 provides the wireless link to phones, tablets or laptops with no cables or jack required. The true wireless form factor leaves both ears free for ambient sound, making the buds suitable for office work, urban travel or outdoor activities where situational awareness is needed. Touch controls handle playback and calls directly on the housing.

Battery and Acoustics

Each charge delivers up to 8 hours of playback from the 16 millimetre drivers with titanium-coated domes and BassUp enhancement. Frequency response spans 5Hz to 20KHz at 71 ohms impedance. Four microphones paired with an AI algorithm suppress background noise for clear voice calls in normal environments.
