Product information

Description

The Koss BT221I is a wireless sports headset designed for active use. It combines Bluetooth connectivity with an ear-hook wearing style and supra-aural cups to keep earbuds in place and deliver audio across a 50–18,000 Hz frequency range. The headset is available in a black and blue finish and is intended for users who require mobility and a stable fit during running, gym sessions or daily commuting.

Advantages

The Bluetooth wireless connection removes cables that can interfere with movement, while the ear-hook design provides a secure fit during physical activity. Supra-aural coupling ensures on-ear contact for clear sound reproduction within the specified frequency range. The compact and lightweight construction supports extended wear during workouts without significant pressure on the ears.

How to use

Charge the headset according to the manufacturer’s instructions before first use. Power on the headset and enable Bluetooth on your playback device; pair the devices following the standard Bluetooth pairing process. Place the ear-hook over the ear and adjust the on-ear cups so they sit comfortably on the outer ear. Use device controls or headset buttons to play audio, adjust volume, or answer calls. After use, power off the headset and store it in a dry place.

Usage recommendations

For optimal fit and sound during exercise, position the ear-hook so it follows the contour of the ear and ensure the on-ear cups make gentle contact with the ear surface. Keep firmware and device Bluetooth profiles updated for reliable connection. Avoid exposing the headset to excessive moisture or impact to preserve performance and lifespan.
