Features

Overview: The JBL Tune 670NC wireless, noise-cancelling, on-ear headphones let you listen without distractions. The headphones weigh just over 6 ounces (without
cable), so you barely know you\’re wearing headphones. With Bluetooth 5.3, you can
listen to your music or carry on a phone conversation without annoying cables. You can
still plug into your device with the supplied 50" audio
cable when you can\’t (or don\’t want to) go wireless. The
Tune 670NC also comes with a
USB-C charging cable.

Drivers: The headphones are equipped with 32mm dynamic
drivers to give you the renowned JBL Pure Bass Sound with clear, powerful bass. The drivers are housed in
sleek, stylish ear cups that sit comfortably on your ears. The soft, padded
headband adjusts for a perfect fit.

Bluetooth: The Tune 670NC wireless on-ear headphones feature
Bluetooth (version 5.3) with HFP (v1.8), A2DP (v1.4), and AVRCP
(v1.6.2) profiles. The headphones allow multi-point connection with a maximum of 2 devices connected at the same time. A future firmware over-the-air update will add the codec for LE Audio, a new Bluetooth wireless standard that requires less energy for transmitting audio.

Ambient Sound Control: The Tune 670NC headphones and the JBL Headphones app provide powerful controls that let you decide how much of the ambient sound you want to let in. Ambient Sound Control includes Adaptive Noise Cancelling, Ambient Aware, and TalkThru features with level adjustment in the app. Adaptive Noise Cancelling lets you listen to music or carry on phone conversations without the annoying distraction of loud ambient noise. The Ambient Aware feature lets in outside sounds so you can hear public announcements or to help you stay aware of your surroundings. TalkThru briefly lowers the volume of your content and raises the ambient noise level so you can have a quick chat without having to remove the headphones.

VoiceAware: During phone calls, VoiceAware lets you hear your voice while talking, making your calls more natural sounding. You can choose a low, mid, or high setting of VoiceAware in the JBL Headphones app.

Voice Assistant: The headphones can access your smartphone\’s built-in Voice Assistant. With a double-click of a button, you can access Siri, Google, or Bixby. In addition, you can activate Amazon Alexa and the Google Assistant app-based voice assistants, to help you with various tasks.

Controls: On board controls are located on the right ear cup, with separate buttons for power and Ambient Sound Control (ANC, Ambient Aware, TalkThru). The multi-function button controls music playback, phone calls, microphone mute, and Voice Assistants. Outside of the multi-function button are the volume up and volume down buttons.

Cable: The headphones come with a 50" flat, tangle-resistant
cable for those times when you need to plug into your device. When the cable is
plugged in, the headphone\’s on-board controls are disabled. Music playback must
be controlled on your mobile device.

Battery: The headphones are powered by a built-in 3.7V,
690mAh Lithium-ion rechargeable battery. The battery charges in
approximately 2 hours via the supplied USB charging cable and a 5V 1A USB port. A 5-minute Quick Charge provides about 3 hours of playback time. On a full charge, the
battery gives you the following battery life:

• Music Playback:
  • Bluetooth On and ANC Off: Up to 70 hours
  • Bluetooth On and ANC On: Up to 44 hours
  • Bluetooth Off and ANC On: Up to 30 hours
