Silence meets power. Silence the distractions. TUNIFI Buds Pro Round takes 45 dB active noise reduction to another level with a bandwidth of up to 5000 Hz. With a wider frequency range, more types of noises can be eliminated. So even on busy commutes and in noisy office spaces, you can fully immerse yourself in your favorite audio. We built Buds Pro with a special wind-through structure that features two holes at the top of the stem.
