Overview: The Bang & Olufsen (B&O Play) H9i is an over-ear headphone with
Active Noise Cancellation (ANC), Bluetooth 4.2, and high-performance sound. The
H9i is powered by a rechargeable battery for hours of wireless listening. The
headphone comes with on-board controls for music and phone calls, a replaceable
Lithium-Ion battery, audio cable, charging cable, and a soft cloth storage pouch.
Design: The Jakob Wagner-designed H9i weighs only 10.4
ounces for hours of comfort. It features 40mm electro-dynamic
drivers that deliver the famous Bang & Olufsen Signature Sound. The H9i features
soft lambskin leather and adaptive memory foam on the ear cushions, genuine
cowhide leather on the headband, and a polished aluminum touch panel.
Touch Controls: The H9i over-ear wireless headphones feature
a polished and anodized aluminum plate on the ear cup that lets you control your
music, phone calls, and ANC, even with gloves on. Touch controls include
play/pause (tap), volume (circular motion), next/previous (swipe
forward/backward), answer call (tap), end call (long press), redial latest
number (double tap), and transfer active call to smartphone (swipe). You can
also control Active Noise Cancellation by swiping up (on) or down (off) on the
touchpad in wireless or cabled mode.
Proximity Sensors: The H9i headphones feature proximity
sensors to detect when you are wearing the headphones, and when you take them
off. The sensors will automatically pause your music when you remove the
headphones. Likewise, when you put them back on again, the music will
automatically resume playing, right where you left off.
Active Noise Cancellation (ANC): The built-in ANC
electronically shuts out ambient noise so you can focus on your music or phone
calls. Microphones on the outside and inside of each ear cup pick up sound from
your environment. These sound waves are mixed with equal, but opposite signals
to cancel out the noise. If you wish to be more aware of your surroundings, you
can turn off ANC by swiping down on the control panel.
Transparency Mode: If you are in a situation where you need
to hear what's going on around you, you can switch on the Transparency Mode. The
built-in microphones used for ANC now amplify your surroundings. You can carry
on a conversation, listen to announcements at the airport or train station, or
hear nearby traffic without removing your headphones.
Bluetooth: The B&O H9i features Bluetooth 4.2 that lets
you listen wirelessly at a distance of approximately 33 feet (10 meters). The
H9i delivers high quality sound that is in sync with your visual media.
Battery: The headphones feature a user-replaceable Lithium-Ion
rechargeable battery (3.7-volts, 770 mAh) that provides up to 18 hours of
wireless listening via Bluetooth with ANC, 23 hours of
Bluetooth only, and up to 24 hours of ANC + control. The battery can be charged in approximately 2.5 hours using the
supplied Micro USB cable. Replacement batteries can be obtained from the B&O
Cable: When the H9i headphones' battery is
exhausted, or you're in an area where you can't listen wirelessly, you can plug
the supplied 50" cable into your music source. A dual-plug airline adapter is included for listening to in-flight
Beoplay App: You can enhance your listening experience with
the free Beoplay App for Android, iOS, and watchOS. The ToneTouch feature lets
you vary the tonality and sound staging to find just the right sound. Each B&O
product has its own individually tuned presets, plus, you can select different
listening presets to match your mood or activity. Any firmware updates for your
headphones are automatically uploaded through the Beoplay App. The app is
available for Android devices running version 5.0 and up, and for iPhone, iPad,
and iPod touch with iOS version 9.0 or later.
