Bass is beautifully deep and powerful, while trebles offer unmatched delicate clarity. Either way you'll be noticing every tiny detail of your favourite music, the way it was intended to be heard. They also feature a new bass port for even deeper, more powerful, and warmer bass. Advanced Active Noise Cancellation With advanced Active Noise Cancellation you can shut out the world to immerse yourself in your music, or just enjoy the silence. The H9i incorporate four microphones which accurately measure the ambient exterior sound and cancel it out with an oppositional audio waveform. It's precision tuned to effectively cancel out the frequencies of traffic, human chatter, and background ambience. Transparency mode lets you instantly tune into the sounds around you at the touch of a button for when you need to be aware. Brilliant Bluetooth With top of the range Bluetooth you can say goodbye to a wired connection and enjoy the liberating freedom of music wherever you want to go. Simply pair the H9i up with your smart phone or tablet. And if you prefer a wired connection (or want to save on battery power) just plug in as normal with the cord included. With two built-in high-quality microphones you can take phone calls on the go too in extreme clarity. Fingertip Touch Control An anodised aluminium plate on the ear cup offers a highly advanced touch interface for instant, easy adjustment. Swipe, tap and wheel actions give you full control over your music and calls, even when wearing gloves. And the Proximity Sensor feature handily pauses the music automatically when you take them off. Extended Staying Power Stay immersed in beautiful music for longer. Recharging via USB, the H9i will keep going for up to 18 hours of music with noise cancellation. So you can have the confidence they'll last all day. And if you should run out of battery, just plug in with the cord. Premium Materials Slightly slimmer than their predecessor, everything about the H9i is quality. Anodised aluminium, genuine cowhide leather, and adaptive memory foam ear cushions provide a winning combination of long-lasting durability and comfort, with a classic but contemporary look. As the leather patinates over time, the H9i age beautifully. And the lightness and softness of the ear pads ensures a tailored, consistently pleasurable fit.
