Description

Defender FreeMotion B552 foldable Bluetooth headphones provide wired and wireless listening with comfortable supra-aural ear cushions and a lightweight head-band design. They include a MicroSD card slot to play music without a phone or laptop, an adjustable headband for a personalized fit, a built-in six-mode equalizer and on-earcup controls for calls and track navigation. A detachable audio cable and up to 25 hours of battery operation (depending on usage) ensure extended use.

Advantages

The combination of Bluetooth and wired connectivity allows uninterrupted listening even when the battery is low. The MicroSD slot converts the headset into an MP3 player for standalone playback. Six equalizer modes (normal, pop, rock, jazz, country, heavy bass) let you tailor sound to different music genres, while on-ear controls and a lightweight, adjustable headband improve everyday usability and comfort.

How to use

Charge the headphones using the USB Type-C port before first use.
