TheOnePlus Buds 4, on the other hand, provides top-tier audio with smart noise cancellation, a coaxial dual-driver system, and dual DACs. This setup includes an 11mm 30-layer ceramic metal woofer for deep bass and a 6mm flat diaphragm tweeter for crisp highs, covering a wide frequency range from 15Hz to 40KHz.
The coaxial design keeps sound balanced and accurate. The dual DAC setup prevents signal interference, with each DAC handling highs and lows separately for cleaner audio.
