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. Active Noise Cancellation The H9s incorporate two microphones which accurately measure the ambient exterior sound and cancel it out with an oppositional audio waveform. Simply swipe to turn the outside world down and get fully immersed in the music. 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 H9s 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 a built-in high-quality microphone you can take phone calls on the go too. 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. Staying Power Stay immersed in beautiful music for longer.
