Defender FreeMotion B580

Affordable multifunctional over-ear closed-type wireless headphones with a microphone, card reader, built-in FM tuner, Li-Pol battery and cable connection. They are one of the most affordable branded bluetooth models of this format in the domestic market. In addition to the low price, they are distinguished by a discreet outdoor design that can be successfully combined with clothing of any style.

The flexible plastic headband adjusts to fit the anatomy of the user's head and generates a moderate clamping force that is enough for a secure hold. Soft, wrap-around type ear cushions trimmed with artificial leather create good passive noise isolation and are completely comfortable for long listening sessions. The Defender FreeMotion B580 headphones are paired with source devices using the Bluetooth 5.0 wireless interface.

Dynamic drivers with a 40 mm diaphragm are capable of reproducing the full frequency range from 20 to 20,000 Hz, delivering confidently loud sound. Direct playback of audio files stored on microSD/SDHC memory cards and listening to FM radio broadcasts is possible. To control the volume and control the playback of tracks, a group of buttons is provided on the left. There is also a microUSB port for charging the built-in battery, which can provide up to 8 hours of active battery life.
