Koss TWS250i Wireless Earbuds

The Koss TWS250i are in-ear true wireless earbuds that connect to source devices via Bluetooth 5.0. They are designed to reproduce a standard frequency range of 20 to 20,000 Hz for both audio playback and microphone input. The package includes three sizes of silicone ear cushions (small, medium, and large) to help users achieve a secure fit, which aids in passive sound isolation. The total weight of the earbuds and case is 32 grams.

Each earbud is equipped with a full-surface touch control system for managing music playback, handling calls, and activating a connected device's voice assistant. A single charge provides up to 4.5 hours of continuous audio playback. The included charging case offers protection and extends the total listening time to 11 hours before the case itself requires recharging. The case features a USB-C port for its power input.
