Charging the unit

Charging the vQuiet before using for the first time is recommended in order to maximize battery life. Low battery is indicated by the LED status indicator on the left ear cup displaying red.

To begin charging, connect the USB cable (micro USB end) to the port behind the right ear cup. Connect the other end of the USB cable to any charge capable USB port or a USB-style charger. Your vQuiet headphones will begin charging, as represented by the red LED status indicator. Once charging is complete, the LED status indicator will shut off.

LED indications

Noise cancellation

Noise cancellation is activated by the switch located on the left ear cup.
Turn the switch to the on position to activate noise cancellation (represented by the blue LED).
The Velodyne logo on the left ear cup serves as the bypass button.

How to connect

To connect your vQuiet headphones, plug the blue marked 3.5 mm (1/8") connector into the left or right ear cup.
Plug the unmarked 3.5 mm (1/8") connector into the audio output port on your audio device.

Daisy chain

When the vQuiet is connected to an audio device, the unused port on the opposite ear cup will become an audio output port, which is capable of relaying the audio signal from your audio device.

To use this feature, connect a second pair of headphones into the unused port on the opposite ear cup.

Wearing the device

Located above the inside of each ear cup are markings for right and left audio channels.
Wear the ear cup marked "Right" over your right ear and the one marked "Left" over your left ear.
Always turn down the volume on your audio equipment before wearing vQuiet headphones. Once the ear cups are comfortably seated over your ears, gradually increase the volume to a moderate sound level.

Adjusting the headband

The headband on the vQuiet is adjustable to fit different head sizes.
Hold the headband and adjust by pulling on the right and left ear cups.
The right and left ear cups should be centered over the ears.

Fold your unit

vQuiet headphones can fold for easier storage. To fold, remove any cables attached to the headphone and push each ear cup inward towards the inside of the band.

Cleaning

Ear cups should be cleaned regularly for sanitary reasons and to prolong the life of your ear cups.
Wipe using a clean soft cloth or microfiber towel. Do NOT use alcohol or sanitizer on the matte painted headphones as damage can occur.

Do not get the speakers or electronics inside of your headphones wet. Liquids and heavy moisture can cause damage to the electronics inside your headphones. Such accidental damages are not covered under warranty.

Using the playback & phone functions

The control module on the vQuiet audio cable has playback, volume, and phone controls so you can flow between listening to music, watching video, and talking on the phone when connected to devices that support these features.

Playback, volume, and phone control functionality varies by media device.

Warnings, safety & care

• 
  To reduce the risk of fire or electric shock, do not expose vQuiet headphones to rain or moisture, and do not open or attempt to open the control module, or any part of vQuiet headphones.
• Keep out of reach of children. Small parts may be a choking hazard. This product is not intended for use by children under the age of three.
• Excessive sound pressure from earphones and headphones can cause hearing loss.
• Consult your physician or audiologist if you have problems hearing, excessive wax build-up or any discomfort after use of vQuiet headphones.

• If any dust or ear wax is inside the ear cup, you may experience a degradation of sound quality.
