Saw this flash sale. Not sure how many left at time of posting (says 33% claimed). The rest of the description is copied from xev's previous posts about these headphones.
Hybrid Active Noise Cancelling utilize both feedforward & feedback dual-mic ANC tech to significantly reduce background noise. They contain microphones both inside and outside the cups. Hybrid ANC can suppress noise at a broader range of frequencies, adapt to and correct errors, and is not as sensitive to how the person wears the headset. This all provides better ANC performance to the listener.
