User Tips
- Understanding Bone Conduction: It's normal to feel slight vibrations from the headset, especially at higher volumes. This is how bone conduction technology transmits sound directly to your inner ear, bypassing the eardrum.
- Microphone Quality: The X7 headset incorporates a CVC Algorithm for intelligent recognition of ambient sound, which helps to improve microphone clarity during calls by reducing background noise.
- Music Management: When transferring music to the 32GB internal memory, ensure files are in MP3 format for optimal compatibility and playback.
