If your DSP Tuning Software is not responding properly or is crashing, it is likely because the proper USB driver has not yet been installed.  There is an easy fix for this, and it does not require you to uninstall anything.

 

1. If the tuning software is open, close it.
2. Go back to your software install files and double-click on “USB Driver”.

NOTE: Make sure to allow it to make changes to your computer if your anti-virus software requests it.

3. After the driver is installed, reopen the software.  Your problem should be resolved.

To skip the tracks forward, you press and hold the volume up button for 3 seconds. To skip tracks backward, press and hold the volume down button for 3 seconds.

The ear pads can be removed and washed.
To remove the ear pads, rotate them anti-clockwise to unlock (see image below).

Once fully dry, align the holes on the inside of the ear pads (highlighted with orange circles in the image below) with the clips on the headphones (located where the red arrows are pointing in the image below), now rotate the ear pad clockwise to lock the ear pads to the headphones again.

Here is how to add music to the Dive Headphones: 1. Place the MP3 music files that you want to transfer to the Dive headphones on your computer, where you can find them again. The sequence is not important, they will be played in alphanumerical sequence. If you want to have a special sequence to your tracks, you can add a number as the first file name. 2. Connect the Dive to your computer with the USB cable. Please use the cable that came with the headphones, since other USB cables may be wired for charging only, and may not work. 3. Your Dive will now pop up in your explorer folder overview as a new drive. Total capacity is about 991 MB. 4. Now you simply drag-and-drop the MP3 files from their location onto the Dive, or you mark the files, copy them and paste them onto the Dive. Do not use folders of any kind, and do not try to place other file types on the Dive's memory. MP3 files with a resolution of 320 kbits/second is maximum quality possible. Please note that the owner's manual contains an error about random play, stating that MP3 play will always be done in random sequence. Unfortunately, this is an error. All replay of MP3 files from the internal memory is alphanumerical, NOT random. As mentioned above, you can add a number to the track title, and the tracks will be played in numerical order, until no more numbers are present, after which replay is in alphabetical order.

Google Play Store: https://play.google.com/store/apps/details?id=com.jbl.tune.update
App Store: https://apps.apple.com/gb/app/jbl-firmware-update/id1548227663

Once downloaded, you can update your headphones firmware from there. 
Below you can see step by step images of the update process.

      

Try all Flex Fit Ear fins included (S/M/L) to find a snug fit for stability during workout. Usually the biggest size that fits comfortably in your ear will provide the most stability.

Once you select that option, the audible voice should state, “connected”. 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.

Horizon's alarm sounds for 3 minutes, then it shuts off, or rather it goes into snooze, for 9 minutes. Then it sounds the alarm again for 3 minutes, followed by snooze for another 9 minutes. After this final snooze period, it starts playing, and keeps on playing until it is manually shut off. The light shuts off with the audio.

Random flashing is an indication that the wireless link between primary and associated speakers was lost and recovered. If this happens too often, it may be caused by interference in the 2.4 GHz ISM band, caused by overcrowding of the band. Sometimes it helps to change location of the speakers, or to shut down other 2.4 GHz devices.

The Bass, Treble and Echo buttons/dials on the control panel on top of the Partybox only applies these effects to the Microphone for Karaoke use.

These effects are not applied to other sources or inputs such as Bluetooth, Aux or USB, the Equalizer must be used in the JBL Partybox app for this (on supported models).

Also, if more bass is desired, there is a Bass Boost button on the top control panel (with 2 levels of Bass Boost: Off, Level 1 & Level 2, switched through pressing the button multiple times). This will be applied to the sources and inputs mentioned above (but not the microphone).

For models that support Game-Chat dial, when you rotate the dial, you will feel a notch that indicates 50% game and 50% chat. Or you can see the status on the top bar of the JBL QuantumENGINE.
