70% Noise Cancelling
Smart noise cancelling technology enhances the pleasure of listening to lower volume levels in noisy environments. It's particularly good at removing low frequencies like jet engine noise, so you can enjoy soft music on flights and in trains and similar places without hearing a distracting buzz in the background. The technology actually creates an equal but opposite waveform to the unwanted noise that effectively cancels it out.

A perfect seal between your ear and headphone will significantly reduce unwanted background noise. With their superb noise isolating characteristics, these headphones not only block out irritating background noise but also deliver superb sound quality at low volume settings.
Neckstrap wearing style
