Product details:

Powered by a custom processor, custom algorithms, and custom speakers, Active Noise Cancellation uses Silent Seal to maximize the outside noise being blocked. Custom-designed 11 mm speaker drivers make music sound powerful, yet nuanced. A full 5-band EQ lets you customize the sound to your preferences. Volume EQ adjusts the tuning as you turn the volume up or down, so highs, mids, and lows consistently sound balanced at any level.
