Open-ear headphones with adjustable hooks

Soundcore V20i earbuds sit outside the ear canal on flexible hooks that rotate to four positions for a secure fit. Weighing 9.3 grams each, they use 16-millimetre drivers with titanium-coated domes and BassUp processing. Bluetooth 5.4 provides multipoint connection, while four microphones and an AI algorithm handle call clarity. The IP55 rating protects against sweat and rain.

For listeners who need awareness outdoors

Runners, cyclists and commuters who must hear traffic or announcements will benefit from the open design. The adjustable hooks stay in place during vigorous movement. Buyers who want active noise cancellation or full isolation from ambient sound should look elsewhere, as this model has none. The LED lights are cosmetic and cannot be disabled for stealth use.

36-hour total playtime with USB-C case

The charging case holds 700 milliampere-hours and delivers three full recharges, extending the 12-hour bud runtime to 36 hours. A 1.5-hour charge fills the buds, while the case needs 2.5 hours via USB-C. If your routine demands more than 36 hours between wall power, this capacity will fall short.
