Performance and User Feedback

Reviews describe the Buds 4 as offering excellent value with flagship-level sound and ANC at a mid-range price. The dual-driver + dual-DAC setup delivers punchy bass, clear vocals, and good separation. ANC is effective for daily commuting and office use, though not quite as strong as premium Sony or Bose models in very loud environments. Battery life and comfort are standout positives.
