How durable are these earbuds for exercise and outdoor use?

The Otium U18 earbuds carry an IPX7 rating, meaning they resist sweat and can withstand immersion in water for short periods. The build is focused on active use, with silicone earhooks and a secure fit that minimizes movement during high-intensity activity. The included carrying case protects the earbuds when not in use, and the materials are easy to wipe down after workouts.

Bluetooth 5.3 provides a reliable wireless link and stable stereo playback with reduced dropouts. The tuned drivers emphasize clear highs and punchy bass to suit a variety of music styles, while an integrated microphone supports hands-free calls and voice prompts.

What battery life and charging features can I expect?

On a single full charge the earbuds give up to roughly 15–16 hours of combined playback when using the charging case, with about 1.5 hours required for a full recharge. A quick-charge capability shortens downtime, and battery status is shown on compatible phones so you can monitor remaining power. LED indicators on the case show charge progress at a glance.
