Product information

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.

Suitable for

  • Listening to music wirelessly at home or on the go
  • Using as a wired headset when battery is depleted or for devices without Bluetooth
  • Merging hands-free calls and music playback with on-ear controls
  • Playing music directly from a MicroSD card without a connected device

Key specifications

  • Connectivity: Bluetooth and wired (audio cable included, USB Type-C charging)
  • Frequency response: 20–20000 Hz
  • Wireless range: up to 10 meters
  • Equalizer: 6 modes (normal, pop, rock, jazz, country, heavy bass)
  • Battery life: up to 25 hours (varies with volume and usage)
  • Weight: 200 g
  • Ear coupling: supraaural; wearing style: head-band
  • Colour: black

How to use

Charge the headphones using the USB Type-C port before first use. For wireless listening, pair the headset with a Bluetooth-enabled device following the pairing instructions in the user manual; use the on-earcup controls to play/pause, skip tracks or answer calls. To play music without a connected device, insert a MicroSD card with audio files into the card slot. If the battery is discharged, connect the included audio cable to use the headphones in wired mode.

Usage recommendations

For best sound and battery performance, keep the firmware updated if updates are provided, store the headphones in a dry place, avoid exposing them to extreme temperatures, and use moderate volume levels to extend battery life and preserve hearing.
