To power on the headphones, place one of the headphones inside your ear and press and hold the center button on the inline mic. You should hear the audio chime and a blue blinking light should appear at the top of the inline mic. If this is your first time connecting to a device, it should immediately go into pairing mode. The device should recognize the T110BT headphone. Once you select that option, you will hear the confirmation tone. If you are trying to connect to a different device, turn the headphones on and press and hold for 3-5 seconds for the headphones to start searching for a different device. The headphones should appear on your discoverable devices within a few seconds. You should hear the audible tone and then the confirmation chime once it is connected. You will see the Bluetooth light alternate between red and blue when it is in pairing mode and then to a slow blinking LED blue light once it is connected to your device.

With TalkThru Technology, music is lowered and speech is amplified so you can easily have quick chats. AmbientAware delivers a more immersive music experience while increasing ambient sounds, providing the safety of hearing your surroundings. You can control them via the buttons on the ear cup and with the My JBL Headphones app

To activate TalkThru Technology, press the LEFT ear for a short press for 1 Second which allows you to clearly hear others for quick conversations without removing headphons. Music volume level should lower when TalkThru is engaged. Press again for 1 second to turn off Talk Thru.

The amber LED lights indicate that you have muted the microphone and the Google Assistant. The JBL LINK will not react to any voice keywords unless you unmute the microphone.

Yes, the app only works when the headphone is powered ON and paired to a source device that has the app available.

If the audio is not centered to your monitor, then you can re-center your headset by doing the following: 1. Position yourself in front of your monitor. 2. Press the re-centering button on the side of your headset (button that looks like a circle) 3. The head-tracking sensor will start the automatic calibration.

To clean your LINK BAR, use a soft dry Microcloth to remove dust and dirt.
We wouldn't recommend using any alcohol as it may harm the product.

It is true that some Bluetooth products have a very loud BT acknowledgment tones. We are sorry, but the level of such tones cannot be changed, and no software solutions will appear.

The JBL Control X is built for outdoor and indoor purposes. If you are placing the JBL Control X outdoor, please be aware that it should not be exposed to directly to the elements (rain, snow, sunlight). We advise you to place the speaker under a roof so the connections on the back won't be exposed to outside sources. If you have placed it correctly under a roof, they can outlast all types of weather.

This may simply be a matter of how the headphone is used. The awareness effect is intended to give the user the ability to hear sounds around them through the microphones on the headset. The effect is apparent in use cases where there is no audio, or the audio is at a moderate level. As with any situation, if the sound level of music is loud, it will mask any sounds, including those delivered by our ambient aware technology

This is a sweatproof headphone, but if you regularly sweat profusely, or use it in rainy weather, damage may result.

Even when reducing volume to minimum on the Bluetooth source unit, it does not reduce the audio signal to zero. In this case the Micro Wireless will playback music at a very low volume.

True Adaptive NC available on Tour One enables real-time monitoring of exterior surroundings and personal attributes like movement, hair, eyeglasses, and automatic adjustments to the NC performance and EQ.

If you don’t prefer the canceling performance's automatic change, you can get a fine-tuned canceling level by choosing “Everyday Mode” in the app.

Adaptive Noise Cancelling - available on Tour Pro+ TWS - listens to ambient environmental noises using external and internal mics then creates the inverse phase back to the listener creating the noise “canceling” effect.
The headphones also allow the listener to adapt or adjust noise cancellation through features like Ambient Aware and TalkThru.

Make sure to press the association button once. If by mistake you pressed it more than once, there is a good chance that association does not take place. Wait until the association process is completed, which takes about 2 minutes, and repeat the process.

This can be caused by the charge arm reaching its thermal temperature cutoff. This is a safety feature to prevent a potential risk. For proper heat dissipation, always be sure to have the charging arm in the open position when your smart phone is attached.

The three JBL Synchros on-ear and over-ear headphones S300, S500 and S700 all have cables with remote control on them. There are two types of remote controls. One is for iPhones mainly. It has white dividing rings between the poles of the jack plugs. The other one is for Android phones. It has black dividing rings between the poles of the jack plugs. This is shown in the owner's manuals as a drawing. The S300 comes in two models, S300i and S300a. They are of course meant for iPhones and Android, respectively. You should either buy the i or the a version, to match the phone you have. But since the difference is only in the remote control on the cable, it is always possible to buy the alternative cable later, as long as they are in stock as spare parts. The S500 and S700 have BOTH cables in the box, so there is no i and a version of these models.

These holes are the microphones for the JBL Link

If your LINK BAR has 4 orange LED lights in the front, this means you have "muted" the microphone which is located on the top of the speaker.
To unmute the LINK BAR use the "switch" and the front LEDs will stop illuminating orange. Now you can use the hot-words to interact with the Google Assistant/Google Search (varies from country).

Privacy information:
We call our button the "PrivacySwitch" for the moments when you don't want the bar to listen for the hot words.
Google has high privacy rules, and one of them is not to share end-user data with any third-party apps.

This is the charging indicator LED. I lights up red when the headphone is charging, and goes dark when charging is complete, or if no charging takes place.

As explained in our Owner's manual, it will adjust the sound to match the placement of your Soundbar, wall or table. When against a wall, the sound reflection will be different than when on a table. This button adjusts the tonal quality to give you the best audio results in either setup.

This is due to your HDMI cables. All cables attached to the HDMI inputs of the SB450, needs to be High speed cables. If your cables do not meet these requirement, then you will experience unstable connection from source to your TV.

Common fixes:

(2) Select the correct audio input source on the remote control.
(3) Check the connections to your TV or other devices
(4) Perform a reset if none of the above is working.
