Overview: The NAD VISO HP70 high resolution wireless over-ear headphones are designed to make
your music sound like an open air live performance. With Bluetooth and aptX HD,
you can enjoy CD-quality audio without being tethered to your audio source. The
HP70s come with a 4' flat,
tangle-free audio cable, and a 4' Micro-USB audio/charging cable. A padded, zippered pouch
is included for storage of the headphones and accessories.
Construction: The VISO HP70s not only sound great, but are
stylish as well. The headphones are made of lightweight materials, such as
smooth brushed metals, beautiful polished finishes, and lush leatherette fabrics.
The ultra-soft ear cups pivot so they fit your head comfortably. The headphones
feature 40mm drivers, especially developed for these headphones, to deliver
clear, accurate highs and natural-sounding lows. The drivers are housed in an
ABS + Polycarbonate enclosure.
Dual Microphones: The HP70 headphones have two microphones
on the right ear cup for improved voice reception during phone calls. The dual
beam-forming microphone configuration helps to enhance voice pickup while
rejecting external sound so your conversations are clear, even in noisy
Controls: The headphone has on board music playback and
phone controls. The controls only work in Active and ANC modes. In Passive Mode,
you will need to use the controls on the connected device. The following
controls are located on the right
- Mode Switch: The 3-position Mode Switch lets you choose from ANC
(Active Noise Cancellation with Bluetooth and the internal headphone
amplifier), Active (Bluetooth and the headphone amplifier, but without ANC),
and Passive Modes (ANC, Bluetooth, and headphone amplifier are off; wired
- Volume: The volume control is a spring-loaded slider that lets
you raise and lower the volume slowly and gradually. Pressing the volume
control activates the Active Monitor feature which instantly reduces the
audio track by 30dB. This allows you to hear your surroundings without
having to remove the headphones.
- Music/Phone Control: The Music/Phone control is a 2-way spring
loaded switch that controls your music playback. Sliding and releasing the
button skips to the next track or the beginning of the current track (or to
the previous track if the current track has just started), depending upon
the direction you slide it. Sliding and holding the control will engage the
fast forward or fast reverse. Pressing the control straight in pauses the
music and resumes playback. If a phone call comes in while you're listening,
you can answer the call (and pause the track) by pressing the control. Once
the call is complete, pressing the button disconnects the call and resumes
RoomFeel: NAD's audio engineers designed RoomFeel technology to
translate the warm, open sound of a live performance into a private headphone
experience. The entire soundstage is expanded, and your digital files are
transformed in clean crisp audiophile-grade sound. RoomFeel is activated in
Active and ANC Modes.
Bluetooth: The headphones have Bluetooth wireless technology
with a range of approximately 33 feet (10 meters). They support Near Field
Communication, which allows you to easily pair an NFC-compatible device by
touching it to the bottom of the right ear cup. The headphones must be in Active
Mode or ANC Mode to work wirelessly.
Active Noise Cancelling: The VISO HP70 headphones are
equipped with Active Noise Cancelling to help you tune out external distractions
so you only hear your music. ANC microphones on the top of each ear cup direct
outside noise into the headphone amplifier, where a phase-reversed signal is
added to cancel out the noise. Active Noise Cancelling can be turned off, and
you can listen to your music wirelessly or in passive mode with the supplied
Tangle-free Ribbon Cables: The HP70s come with two 48" flat ribbon
cables that are designed to resist tangling.
One is an audio cable for use in Passive Mode. It has a straight 3.5mm plug for
connecting to the right ear cup, and a right-angled 3.5mm plug for connecting to
your source device. With the included 1/4" adapter, you can listen to your home
audio components, or use the airline adapter to enjoy the in-flight
entertainment on most flights. Also included is a Micro USB cable that is used for charging the
internal battery, and for plugging into your computer to listen to audio content.
Rechargeable Battery: The headphones are powered by a 3.7V
600mAh Lithium-Ion rechargeable battery. The battery charges in approximately 4
hours via USB power. A fully charged battery has approximately 15 hours of
battery life in Active Mode with ANC.
