5.2 Active Noise Cancellation (ANC)
The earphones feature Active Noise Cancellation (ANC) with up to 28dB noise reduction. This technology instantly cancels out ambient noise, effectively blocking out sounds like the rumble of a subway or the clatter of coffee machines, allowing for an immersive listening experience.
5.3 Environmental Noise Cancellation (ENC) for Calls
Equipped with a four-microphone array and a high-definition call noise cancellation algorithm, the ENC feature precisely captures your voice and cancels out environmental noise. This ensures that the person on the other end of the call hears only your voice, even in noisy environments like a subway or a busy street.
5.4 Sound Quality and Design
The Ohr636 earphones feature a large dynamic driver unit with a 30% increase in diaphragm area, delivering deeper bass, a wider soundstage, and more impactful drum beats. The Bionic Sound-Collecting Chamber Design effectively reduces headphone sound leakage, ensuring 99% sound clarity and 98% reduction in sound leakage. Multi-band bass enhancement technology further reduces low-frequency distortion for immersive and powerful bass.
- Original Sound Quality: Experience clear and transparent highs, warm midrange, and powerful lows, with every detail fully captured. Supports AAC and SBC high-definition audio.
- Surround Sound: A multichannel algorithm constructs a stereo sound field, synchronously enveloping the left, right, front, and back for a panoramic audio experience.
