It is possible to pair two of the same model of JBL PartyBox speakers together through TWS (True Wireless Stereo) mode.

PartyBox On-The-Go*/On-The-Go Essential*/100:
Connect just the left PartyBox with the chosen device first, with the right PartyBox turned off. The speaker that is connected first will automatically be the left channel. Now turn the right PartyBox on and continue with TWS pairing (detailed below).

*The PartyBox On-The-Go and PartyBox On-The-Go Essential are compatible with each other in TWS mode.

PartyBox 200/300/1000:
A button (L/R) on the rear of the speakers is used to assign the correct channel to the speakers after pairing is made.
In order to activate TWS mode, press and hold the Bluetooth button on the first speaker until the notification chime sounds, about 5 seconds. Then press and hold the Bluetooth button on the second speaker until the notification chime sounds (as seen below). TWS mode is now activated. To disable TWS, press and hold the Bluetooth button on either speaker, or power off one speaker.

Partybox 110/310/710/Encore/Essential:
Press the buttons labelled TWS on both speakers to connect the speakers in TWS mode (pictured in item 2 in the image below, with two speakers on the button).

TWS can be activated and deactivated remotely in the JBL Partybox app, in addition to assigning the left and right channels to the correct speakers.
Once the TWS connection is setup, it will be in Stereo mode by default if both speakers are the same model, otherwise the speakers will be in Party mode by default if different Partybox models are used. You can also switch between Stereo and Party mode in the JBL PartyBox app if two of the same Partybox models are used.

Please note: In order to achieve TWS mode, the speaker must be the same model with the exception of the PartyBox 200 & PartyBox 300, and PartyBox On-The-Go & PartyBox On-The-Go Essential which can be paired together via TWS. You cannot achieve TWS with a PartyBox 1000 and a PartyBox 300. You cannot achieve TWS with a PartyBox 100 and PartyBox 200. However, it is possible to connect a maximum of two of either the JBL PartyBox app compatible models (PartyBox 110, 120, 310, 320, 710, Encore or Encore Essential) together in Party mode - the two speakers then do not need to be the same model, but Stereo mode will not be possible.

If you are experiencing sound fading in and out (pumping) or volume levels changing while playing your instrument, this is known as limiting. The sound being sent into the PARTYBOX may be too loud which will cause the limiter in the speaker to kick in. This can cause the volume levels to dip. This is done to protect the speaker from playing louder than it’s rated output, and it likely means that the instrument input level on the PARTYBOX is set too high. Please perform these steps to calibrate your input level and to prevent pumping:

 

1.  While music is playing via BT or line input, set the volume on the PARTYBOX to a comfortable listening level.
2. Stop playing the music.
3. Turn the instrument/guitar input volume on the PARTYBOX all the way down.
4. Connect the instrument to the instrument/guitar input on the PARTYBOX.
5. Set the volume on your instrument to max.
6. Start playing the instrument and begin turning the instrument/guitar volume on the PARTYBOX up. The instrument should sound perfectly normal without any pumping or swelling. Continue to turn up the volume until you start to notice pumping or swelling. When you hear this, turn the volume back down a little bit until the pumping completely stops. You have now calibrated the input level for that instrument. During this step, as you are turning up, if it gets too loud, turn down the main volume on the PARTYBOX to a comfortable level, and then continue.

You should now use the main volume on the PARTYBOX to set the loudest volume for your instrument and can use the volume control on your instrument to adjust the level up or down.

 

NOTE: Whenever connecting a different instrument, you will likely have to repeat this process as all instruments (guitar pickups) have slightly different output levels. This is how you can ensure maximum performance out of your PARTYBOX.

The new PartyBoost does not support the previous Connect and Connect+ features. For example: You will not be able to successfully connect the new PartyBoost enabled Flip 5 with a Connect+ enabled speaker like the Pulse 3 or Flip 4. You will not be able to connect the Boombox 2 to the original Boombox speaker.

If you create a Stereo Pair using the JBL Portable App and you come within range of additional PartyBoost compatible speakers while they are ON, the app will find these speakers. This will break the stereo pair and create a mono PartyBoost group that includes all active speakers that are in proximity. This only happens when the JBL Portable App is actively running on the source device, including when it is running in the background, and when these other speakers are ON. To avoid this scenario, make sure the app is completely closed, without running in the background before coming near any additional PartyBoost speakers that happen to be ON.

NOTE: The Portable App does not need to be running in order to enjoy Stereo sound from two speakers

If the two buds lose connection to each other, you can choose to force-pair the main/right bud to the secondary/left bud or the other way around.
For both buds, triple-click the button on one ear bud to pair with the other ear bud.

First time you perform the pairing, it can take several minutes to establish connection. If more than five minutes go by with no result, please switch both units OFF and ON again.

Check if the tower and subwoofer’s LEDs are in solid white color. A blinking LED means a disconnection. In this case, hold RESET on the back of the tower or subwoofer for 5 seconds to enter pairing mode. On the touchscreen, tap “Speaker Setup” > “Pairing” > “Tower Setup” or “Subwoofer pairing”, then follow the onscreen instructions to pair with the digital hub again.

In most cases when a Computer/PC/Laptop has issues connecting to a Bluetooth device (Portable speaker, Headphones, Active speakers), it's caused by your Computer/PC/Laptop's Bluetooth driver (software).

The driver (software) should support the following Bluetooth protocols, to be able to play music/sound from your Computer/PC/Laptop:

• A2DP (Advanced Audio Distribution Profile) driver for your Computer/PC/Headphones to transfer music.

• AVRCP (Audio/Video Remote Control Profile) driver to send skip/forward/pause/play music to your device

Always get the latest driver version available for your Computer/PC/Laptop.

To download the correct driver (software), visit the manufacturer's website of your Computer/PC/Laptop. They usually have a "Support/Download" section where you can find the correct driver. Otherwise, we advise you to contact their support.

Try a manual pairing of the headset and the dongle.
Hold the power button in the "On" position for 5 seconds on the headset, and then hold the button on the dongle for 5 seconds. This should force a manual pairing, allowing the PC to again recognize the headset.
Be sure to check multiple USB ports (to confirm it’s not an issue with the USB port).
If the dongle can’t be manually paired either, please contact customer support.
 

To power on and pair the headphones, remove the ear tips from the charging case. If this is your first time using the headphones, they will automatically go into pairing mode. You will see the blue and red LED light flash on the RIGHT and LEFT ear as it attempts to pair with your device. Make sure your device is in range and BT settings are ON. The JBL True Wireless Flash X should pop up on your list of discoverable devices within 3-5 seconds, tap and connect. Once connected, you will see a slow blinking blue light below the UA logo on the RIGHT and LEFT Ear. This headphone allows you to use the ear tips in Stereo or Mono mode. If you wish to just use the LEFT or RIGHT ear, simply place the ear tip you do not wish to use back in the charging case.

Every person has different preferences for wall mounting products. Nevertheless, we tried out varies options and found this to be the place for optimal sound performance.

1. Use the included "Wall-mount guide" that came with your LINK BAR.
2. From the down edge of your TV screen, measure 50mm (using the guide for the screws) or 5 cm or 2 inches depending on the country.
3. It will perfectly align the LINK BAR close to your TV and give the best performance.

Also, you won't have to deal with HDMI cables being too short!

These are our recommendation if you want to place it further down, be our guest!
The sound and performance will still be magnificent!

Although both speakers have the same tweeter and woofer, because the Arena 170 has a larger cabinet, it will produce deeper bass. This also means that the Arena 170 can handle more power, versus the Arena 130 speakers. Please see product spec. sheet and/or manual for more details.

While the speaker provides a single wireless microphone in the box, it has the ability to work with two wireless microphones. Some units will include Mic A, while others will have Mic B. If you are looking to order the second mic, you must first determine which mic you already have.

 

1. Power on the microphone.
2. Long press the Power button. The mic will power off. Keep pressing the button until the mic shows the version.
   1. 6A08 = Mic A. You will want to order Mic B. Part #050100-000014
   2. 6B08 = Mic B. You will want to order Mic A. Part #02-UMI033-XX0
3. Please call 1-800-336-4JBL (4525) to place your order.

Yes, the 8 hours time is for conference calls and music playback, but will of course depend on volume level and music content.

Yes, this is correct. In order to minimize interference between speaker and microphone during telephone conversations, one speaker unit is deactivated.

- Try to disconnect some devices from your Wi-Fi network. Some routers may have weak performance, which can cause issues and poor connection to all devices in your network. - If your router supports 5Ghz ( 802.11N or AC ) and you have devices that are capable of using 5 GHz Wi-Fi then switch to that specific network for best performance. - If you have a lot of ( Legacy / older than 5 years ) devices on 2.4GHz network, try limiting them to max. 6 connected simultaneously

The JBL Xtreme will no longer appear in the JBL Portable app while using Apple devices with iOS 14 or later installed, due to incompatibility. 
You can continue to use the speaker as normal with these devices through Bluetooth or Aux connection, but it will no longer appear in the app. 
There are currently no plans to release a new Firmware as the JBL Xtreme has been discontinued. 

Make sure the volume control on the headset is turned up. Rotate the volume wheel on your headset to increase the volume. If you're connected to the PC via USB, check that the default device is selected under Control Panel > Sound > Playback. Select JBL Quantum 600 or Quantum 800 Game, right-click, and select "Set as Default Device". Check your headset's game-chat balance dial and ensure that the balance is correct. Check the JBL Quantum 600 or Quantum 800 Game device and make sure it is not muted or turned all the way down.

Make sure the headset volume control is turned up. Rotate the volume wheel on your headset to increase the volume. Check that the correct playback device is selected under Control Panel > Sound > Playback. Select the correct device, right-click, and select "Set as Default Device". Check the computer volume levels and make sure it is not muted or turned all the way down.

Select the correct device, right-click, and select "Set as Default Device". Check the computer volume levels and make sure it is not muted or turned all the way down.

We've intentionally designed the flip-up boom mic to stay affixed to the headset. We know from experience that losing or breaking the detachable mic is never fun. Therefore, we designed the mic to fold neatly into the headset - this design also allows the mic to automatically mute when elevated. If you're wanting a detachable mic, please check out the Quantum 100 or the Quantum ONE.

If you are having difficulty with the noise cancelling feature while on your PS4, please check your side tone setting in QuantumENGINE by connecting your Q800 to your PC. Please note that ANC will not work properly if the mic is on and sidetone is greater than 0. We recommend either muting the mic or change the sidetone in the JBL QuantumENGINE to 0.

What’s New

1. Fixed issue where there was no sound when using earbuds with conference software on pc, i.e. Zoom, WebEx, Skype
2. Performance improved

Yes, rinse it under a faucet or under the shower, but not under full water pressure.

If you find yourself encountering audio dropouts or interference coming from your surround speakers when they are not docked on the main unit, here are a couple of tips to try to remedy that.

1. Try moving any wireless routers that are near the sound bar further away.

2. Reboot router so it can auto select a new frequency channel, since the sound bar and router may be on the same channel resulting in audible interferences

3. Re-position the surround speakers so they are closer to the main unit.

4. Re-calibrate the surround speakers

5. Adjust the volume on the sound bar and gradually raise the volume, if driven to hard the sound bar speakers can distort

When you are installing new apps or adding content to your LINK BAR, the system may be a bit slower when dealing with multiple things.
Here is a couple of things you should know.

1. You need a speedy internet connection to download all the content you added.
2. Wait for everything to be finished, then you can enjoy the system without any issues.
3. Reboot LINK BAR after installing all apps. A fresh reboot can help and enhance performance.

Check your audio cables and make sure they are secure. Set the volume of the source device (if applicable) to a higher level.

This is most likely due to CEC function. Some our soundbars supports CEC commands from your TV, and if some CEC commands will make the speaker react in a way you do not like, we suggest you disable all CEC functions from your TV. Please note, that your Soundbar will not turn on when your TV is turned on, due to disabling the CEC function.

Some mobile phones, tablet computers or laptop computers will react to the powerful magnetic field from the loudspeaker drive units that are right beneath the top panel. Some have magnetic sensors built in, which means that covers with magnets in the lid can turn the phone ON when the cover lid is opened, and turn it OFF again when the lid is closed. Such phones may turn off if placed on certain portions of the top panel. Other devices are simply sensitive to magnetic fields. You can move the device around on the top of your L8 or L16 speaker, to check if some locations are better than others. The magnetic fields are most powerful near the front panel, where the speaker units are mounted. If you cannot find a location which works, your particular phone, tablet or laptop cannot be used while resting on the top panel of your speaker. There are no reports of damage to any devices because of this phenomenon.

Do not worry, pairing both devices is easy and quick. Press the "pairing" button on the back of the Omni Bar, then press "pairing" button on the subwoofer. They will start communicating with each other, and when both devices show white light in the LED on the back, that indicates that they are paired.

Our Control X Wireless speaker has two different patterns for switching on, when using either battery or AC power. When using battery, turning on one speaker in either stereo mode or association mode (4 speakers connected), all will turn on simultaneously, no matter which is primary or secondary. When connected to AC power, switch on the primary speaker in stereo or associated mode, and the secondary speakers will follow. If you have associated speakers stereo or 4 speakers connected, then you have to press primary speaker's power button for more than 2 seconds, then the primary will send signal to secondaries, and they will wake up. It takes approx. 30-60 seconds before all are switched on. If your press it too short (less than 2 seconds), the primary speaker will not "pair" the secondary speakers together. Switch off the primary and start over again.

There are two ways to blow speakers. The first is the one we all know and understand. If you pump 500 watts into a speaker that is only rated at 100 watts, kaboom, it blows up. As a result, very few of us do this. So then why are all of these poor, helpless speakers blowing up? Because of the second reason, under-powering. It's really a misleading term, but let's try to explain. First let's take it to the maximum. Example: You have a 1000 watt speaker and a 100 watt amplifier. The way you like to listen to music requires 300 watts. Typically, you will ask your amp to put out that 300 watts that you want to hear. The amp will do it, but it will clip and distort. Unfortunately, the human ear can't hear distortion until it reaches almost 10%. By that time it's usually too late. The speaker keeps trying to reproduce this distortion that it's not capable or reproducing and eventually it blows (usually the tweeter fails first). If you are blowing speakers with an amp that has a power rating lower than your speakers, you are pushing your amp too far, causing it to clip, and blowing speakers. If you are pushing your system too hard, it is suggested that you realize your systems limitations or recommend that you get a more powerful amplifier. Please realize, if you only buy speakers that will handle more power and not a more powerful amplifier, you won't solve the problem. The speakers will still blow, because it is distortion that is blowing them, not too much power.

This can be caused by dirt and dust accumulating on the charging arm, which can reduce the effectiveness of the adhesive. Clean the surface of the charging arm with a wet cloth or alcohol wipes. Do not use paper towels as these can leave paper debris.

You might accidentally pressed volume- and surround button at the same time. This combination activate a special demo mode for the product. To stop the demo mode, either perform a full reset by holding down volume+ and surround button for 5 seconds or when power is on, press volume- and surround button again for 5 seconds.

It is usually not necessary to replace an unresponsive remote control. First, check to see if there is a small plastic tab extending out of the base of the remote control. This is a protective sleeve installed on new remote controls to prevent the battery from draining. Pull this tab to remove the plastic sleeve. The sleeve must be removed before the remote will operate. If the sleeve was removed or not present and the remote control is not working then a new battery should be installed before replacing the remote control. There is a small slide out drawer that houses the battery. The battery type will be either CR2025 or CR2032 for remotes of this size. Replacement batteries are commonly available from most electronic and convenience stores that sell small batteries. Check the number on the original battery and replace it with a battery that uses the same number. These steps will typically solve the problem.

Yes, this is a normal characteristic of this system.

With some Blu-ray discs, you have to go to the Settings Menu of your Blu-ray player and select "Bitstream" or "Bitstream Native". This will carry the DTS HD Master signal to be decoded in the AVR, and the AVR front panel should show the correct text.

1. Ensure that your JBL One app device is less than 10m/33ft from the speaker during the initial set-up.
2. Ensure it is plugged into power and the power LED is illuminated.
3. Unplug the power cord, wait 10 seconds, reconnect the power cord and allow the speaker to power up.
4. Temporarily relocate either the speaker or router so that they are closer together.  If the connection succeeds, the original location may be too far from the router to maintain a stable connection.
5. Try using a different device with the JBL ONE app installed and connected to your home network.

1. Ensure that your Harman Kardon One app device is less than 10m/33ft from the speaker during the initial set-up.
2. Ensure it is plugged into power and the power LED is illuminated.
3. Unplug the power cord, wait 10 seconds, reconnect the power cord and allow the speaker to power up.
4. Temporarily relocate either the speaker or router so that they are closer together. If the connection succeeds, the original location may be too far from the router to maintain a stable connection.
5. Try using a different device with the Harman Kardon ONE app installed and connected to your home network.

It is normal because USB-PD (USB Power Delivering) fast charging has a higher charging speed at the beginning and lower when your device soon to be full.

Yes, it will power off after removing charging cable. It is by design.

One explanation can be that your OMNI 50+ is part of a 5.1 system with your Omni Bar, which will make the surround OMNI 50+ left and right rear speakers act as "secondary", and Bluetooth connection is not possible to secondary speakers. To use the OMNI 50+ as a portable speaker again, simply perform a reset of the speaker by pressing the reset button for 5 seconds. Please note that after resetting your OMNI 50+, it is no longer part of the 5.1 wireless system.

Dual band routers that have 2.4 and 5 GHz connection bands. If devices connect on different bands, they cannot see one another. Please make sure your phone and speakers are both connected to 2.4 GHz or 5 GHz and that there is no AP isolation activated between them.

If your Wi-Fi network name has special characters, such as (, `, \, ', ", or ), then please change the name of your Wi-Fi network, as these characters are not supported. After changing the name, you can go ahead and setup the speaker to your Wi-Fi network.

First try turning power to the No. 40 OFF, disconnect then reconnect the existing comms cable between the No. 40 Audio and Video processors, and power the No. 40 ON. If this does not help try a different comms cable, this is a straight through 4 conductor cable with a 4 pin connector on each end. If replacing this cable does not help contact one of our authorized service centers for repair assistance – their contact information is under the SUPPORT tab on the Mark Levinson website.

In order to get the earbuds to power on, please remove the plastic film to allow the pins in the charging case to make contact with the contact plates on the earbuds.

Yes, this is normal for the N60NC BT. It disappears within about 20 seconds.
