concert in a stadium is often about 110dB.
90dB 8 hours
95dB 4 hours
100dB 2 hours
105dB 1 Hour
110dB 30 minutes
115dB 15 minutes
120dB Avoid as damage may occur

Wireless Pairing
Pairing is the process required to create a link between Bluetooth
devices to allow wireless connection. You must pair a device with the
HP70 headphones to be able to make a BLUETOOTH connection for the
rst time.
Before you start pairing operation, make sure that:
• The Bluetooth device is placed within 1 m (3 feet) of the headset.
• The HP70 is charged suciently.
To pair your device:
1. Turn on the Bluetooth feature on the source device.
2. Open the Bluetooth settings on the source device.
3. Press the pairing button for 3 seconds on the HP70. The LED will
ash BLUE.
4. Select the HP70 headphones from the device list.
5. Once the HP70’s link has been established with the source device,
the LED will turn solid BLUE.
6. If pairing fails, the LED will turn solid RED.
NFC Wireless Pairing
HP70 supports Near Field Communication (NFC) so you can easily pair
your headphones. For pairing follow the instructions below.
NOTES
• The supplied conversion plug may not be usable depending on the type
of aircraft.
• Do not use these headphones when the use of electric devices on the
aircraft is prohibited, or when the use of personal headphones to listen
to on-board music service is prohibited.
• Audio output jack congurations may vary on airplanes. Airline audio
quality may not equal that of your home audio equipment, or portable
sources provide.
NAD recommends not to use these headphones as aviation
communication equipment. They are not engineered for many
environmental conditions common in commercial or non-commercial
aircraft (including, but not limited to: altitude, temperature, noise
conditions, unpressurized aircraft) and could result in possible
interference to critical communications.
To pair your device using NFC:
1. Turn on NFC and Bluetooth on the device you are pairing.
2. Place your Bluetooth enabled device against the bottom of the
right ear cup.
3. Accept the pairing on your device when prompted.
Note: NFC is a short-range wireless communication. Pairing devices
are required to be within a few centimetres of the headphones to
communicate. If pairing is unsuccessful, refer to the device’s manual to
nd its NFC touchpoint. Repeat the steps shown and ensure the located
touchpoint is placed against the right ear cup as directed in Step 2.

USING THE NAD VISO HP70 HEADPHONES
The ear cups are marked with “L” and “R” to indicate the left and right
sides of the headphones. Be sure to put them on correctly to enjoy
your audio as originally intended and maximize your personal music
experience.
Earphone Mounted Controls
The main controls are located on the rear part of the right ear cup. They
are used to control Volume, Noise Cancelling, and your smart device

space. The described function only works in Active Noise
Cancelling mode. When activated, the surroundings will be
amplied through the headphones.
Active Noise Cancellation and Amplier
The power modes use the internal (rechargeable) battery.
Although battery life will vary upon usage, the average life is
15 hours.
In Active Noise Cancelling mode, the "Noise Cancelling"
feature has been activated with the internal headphone
amplier. The 3-position Power Switch will be “GREEN”.
In Active mode, the internal headphone amplier is active.
The 3-position Power Switch will be “BLUE”.
In Passive mode (OFF), noise cancelling and amplier are
turned o. No power is required as the headphones are
powered by your audio source. Note: Bluetooth connection
will not work in this mode.
