Dynamic 40mm alloy drivers deliver 3D stereo sound with enhanced bass response and clear trebles. An integrated omnidirectional microphone with DSP noise suppression filters ambient noise during voice calls.
4. Ergonomic & Portable Foldable Design
Weighing under 200 grams, the B570 features a flexible, adjustable aluminum head beam wrapped in artificial leather and soft protein ear cushions for extended wearing comfort. The earcups fold inward for compact storage during travel and daily commutes.
