    In-Ear Fit Guide

    A proper fit is the most important thing when using in-ear headphones (wired, wireless, TWS). Without a solid, tight fit the headphones will sound thin (lacking bass), not very loud, and will do a poor job of blocking out unwanted sounds.

    In-ears, unlike an earbud design, are meant to be pushed into your ear canal, creating a tight seal. If this seal is not accomplished, you will not experience good results.


    1. Typically speaking, the medium sized ear tip is already installed on your in-ear headphones. If it feels tight or loose, try the other sizes.
    2. As you try each ear tip, rotate forward and/or back until you create a tight seal as seen here. In-Ear Fit Guide - image.png
      NOTE: The image shows a stick style in-ear, but this applies to any in-ear design.
    3. As you are twisting and pushing you will hear the sound quality changing. When you accomplish a tight seal, you’ll hear it. You will have more bass than in any other position, and the leakage from outside noise will be minimized before ever turning on Noise Cancelling (if your headphones have Noise Cancelling).
    4. If you have one of our headphones that uses the JBL Headphones App, check in the app to see if there is a “Check My Best Fit” banner. This feature will walk you through getting the best fit and will let you know when you’ve accomplished it.


    While this may seem a bit daunting, after doing this a few times, inserting the in-ear headphones into your ears and getting a good fit will become second nature and will take a second or two each time, not minutes. But it is definitely worth spending the few moments the first time around, in order to get the most out of your in-ears.

  • If the Harman Kardon Go + Play is not stable or wobbles on a surface, one of the legs on the bottom of the speaker is adjustable with a Philips screwdriver. The adjustable leg is the one with a screw is in the center of the leg. 
  • If you are having trouble with distortion or drop out, try the following suggestions:

    Move the audio source closer to the speakers

    Move the speakers closer to each other

    Make sure the streaming speaker (host) only connects to one audio source, disconnect the Bluetooth connection between the streaming speaker (host) and other audio source

    Make sure the audio source only connects with one streaming speaker (host), disconnect the Bluetooth connection between the audio source and other speakers

    Restart both your speakers and the audio source

    Make sure speakers are away from other sources of wireless signal – you could be experiencing interference

    Re-pair the audio source with your speaker

    If you’re streaming audio content from the internet, the issue could be with the internet connection and not your speaker

  • Many Harman Kardon, JBL and AKG products run on rechargeable batteries. In most cases, these batteries will provide years of excellent service and keep the music playing for many hours.

    WARNING – the rechargeable batteries inside our products are not user-serviceable. Please do not attempt to open the product or replace the battery. Doing so will void your warranty.

    Battery issues fall into three categories:

    • Your speaker or headphones run out of power after only a short time.

    • The speaker will not play at all because the battery will not hold a charge.

    • When you plug in the cable to charge your speaker, sometimes it charges and sometimes it does not- the red charging LED or other indicator might not come on.

      Here are some things to try that often fix these issues.

    1. It could be as simple as a bad USB charging cable. If you have other charging cables, give them a try. (Be sure that the cable has the same type of connector as the original one that came with your product.)

    2. Same for the charger- if your product charges by USB, try a different USB charger. Be sure that it is rated at least 2.0a (2 amps) output.

    3. Try other electrical outlets at your location to be certain it is not a local wiring issue.

    4. Charge the product overnight for at least 8 hours.

    5. When you plug the charging cable into the speaker or headphones, is the connector stable, or can it be wiggled around? If it can be wiggled, this could indicate that the charging port has been damaged or come loose. Sometimes wiggling the connection restores charging power.

    IMPORTANT: Some products such as Xtreme, Xtreme 2, Boombox, Partybox 100 & 300, GO+Play and the Onyx Studio series do not use USB charging. Instead, they have a specialized charger. Do not attempt to charge these products with other cables or chargers.

    If none of these fixes the issue, it could be that the battery has died or is losing its capacity, or that the charging connector on your speaker is damaged. Please contact us so we can assist you. Be sure to mention that you have tried the steps in this Battery & Charging FAQ so that our agents do not ask you to repeat these steps.

  • Three things to know about Bluetooth (BT)… 
    1. Pairing:  Pairing is like creating a new contact in your phone’s Contacts list.  You have to do a little bit of work to create the contact, but once you do, connecting with that person in the future is fast and easy. 

    Let’s put this in terms of phones and speakers (or headphones).  Your phone needs to become acquainted with your speaker.  This is called pairing. 

    NOTE: Throughout this article, we will talk about your phone. However, it applies the same to tablets, laptops, computers and any other Bluetooth (BT) source device.
    To get this started, you have to put the speaker into pairing mode. You may have to press a few buttons to make this happen.  All speakers work a little differently, but generally speaking, follow these steps…
    1. For most speakers, quickly press and release the speaker’s BT button.  However, with some speakers you may have to press and hold the BT button for a few seconds.  Most speakers make a noise or have a blinking LED to let you know they are in pairing mode. 

      If this does not get you into pairing mode, check your owner’s manual or look for an article pertaining to your specific speaker.
    2. Go into BT settings on your phone.  Search or scan for available devices.
    3. A list of available or discoverable devices will appear on your phone.  Select your speaker.
    4. Two things have just occurred:
      • Your phone and speaker are now paired.
      • Your phone and speaker are now connected so that you can listen to music.
    NOTE:  Just as you can have many people in your phone’s Contacts list, you can have many speakers and headphones in your phone’s paired devices list. 
    2. Connecting:  Once you have paired, your phone remembers your speaker, and your speaker remembers your phone. However, the two must connect to play music through the speaker.
    Automatic Re-connection:  Let’s say your speaker is at home in the living room, and you leave for the day. When you come home and are within range of the speaker, your phone will automatically re-connect to it (assuming it is turned on).  You can press play on your phone, and the music will play though your speaker.  Of course, if your speaker is off, you will need to turn it on first. NOTE:  Some speakers make a sound when they re-connect. 

    Automatic re-connection does not always happen.
    • Some phones may not work like this.
    • Someone else may have connected to the speaker.
    • Perhaps you connected to a different speaker while outside of your home.
    Manual Re-connection:  If your device does not automatically re-connect, you can re-connect manually…
    • Go into Bluetooth settings on your phone and make sure BT is on.
    • Select your speaker to re-connect and play music.
    Some speakers allow several phones to be connected at the same time.  Others allow only one at a time.  Therefore, if you are unable to re-connect, it could be that some other phone is connected to the speaker.  In this case…
    • Go into the other phone’s BT settings and disconnect the speaker or turn off BT.
    • Then follow the steps above to manually re-connect your phone to the speaker.
    NOTE:  Do NOT Unpair or Forget the speaker in your phone’s BT settings, as this will require you to repeat the Pairing steps above. 
    3. Resetting:  This is a drastic step and should only be done if the unit is not operating correctly. Do NOT reset your speaker every time you want to connect.  Resetting erases all pairings to all phones. You would then have to Unpair or Forget this speaker from each and every phone, and start the pairing process all over again. Check your owner’s manual or look for an article with more detailed BT instructions on your specific speaker or headphone model.

  •  We strongly recommend that you use the original packaging with the existing shock-absorbing packaging material.

    Don’t have the original packaging?

    Please follow these important guidelines to ensure that you pack the device safely and avoid shipping damage.

    • Never use bubble-wrap only.
    • Choose a sturdy cardboard box that permits at least 10cm of packaging materials between the device and the walls of the box. Putting the device into a cardboard box without proper shock-absorbing packaging materials will result in damage to the device.
       Air-bubble isolation and foam beans is advisable only for very light-weight items.
    • Use packaging materials that cannot move around, and cannot be damaged by the device moving around and being shaken about.
    For all larger items such as sound bars, subwoofers and PartyBoxes

    In addition to above instructions:
    • Use either panels of foam rubber or strong cardboard plates, or other sturdy materials that keep the device completely still inside the box, even if the box is shaken with considerable force.
    • Keep in mind to still have 10cm or more of packing materials between device and box walls.
    This way, your device should reach its destination undamaged.
  • This article mostly pertains to car audio but can also be used when setting the crossover for a home theater system.

    When setting up full-range speakers (2-way, 3-way, etc.), it is not necessary to use a HPF.  If a speaker’s frequency response is 40Hz-20kHz, this means that it naturally rolls off at 40Hz on the low end, and 20kHz on the high end.  So even if it is asked to reproduce 30Hz, it won’t, and all is good.

    However, why make the speaker try to reproduce frequencies it can’t, or make the amp work any harder than it needs to.  For this reason, it is good practice to set your HPF at the lowest frequency listed in the speaker’s frequency response. So, if the speaker’s frequency response is 35Hz-20kHz you would set it to 35Hz.

    Of course, there is no harm in setting it higher than 35Hz, if you’d like, or if you have a subwoofer handling the lower frequencies.  Another reason you might set it higher, if you have a car system with 4” speakers in the rear door, but 6x9’s in the front door.  You can let the 6x9’s handle all of the low frequencies while the 4” speakers take everything above 100Hz (for example), even though the speaker's frequency response may go down to 55Hz.

    There are two other methods for setting the HPF on your speaker.

    1. If your speaker plays fine without using the HPF:  Begin playing music and slowly turn up the HPF until you notice that the bass response is diminishing, then slightly turn it back until you get full response again.  This now guarantees that you have filtered out the bass that the speaker cannot reproduce without sacrificing any low frequency reproduction of the speaker.
    2. If your speaker is popping or crackling on really deep bass notes:  This may be due to installation location, or simply pushing too much bass to the speaker.  In this case, turn up the HPF until the popping stops.  This is not something that is normally suggested, but if you have a full system up and running and are happy with the results except for some popping in particularly small speakers, adjusting the HPF up a little may help.
  • Troubleshooting on a Wi-Fi Network:

    1. Unplug your router, then plug it back in.
    2. Give the router a minute or two to start up again.
    3. Make sure your phone, tablet, or computer has reconnected to the correct Wi-Fi network before checking the SmartThings app again, making sure not to connect to a guest network, as this can prevent your devices from connecting to your speaker.
    4. Use the router’s default “WPA2” security setting. Do no use “WEP” security setting on the router as this is not supported to connect your speaker with the internet.
    Troubleshooting with ethernet:
    1. Check the ethernet cable to make sure that the ethernet cable is firmly plugged in to both the router and your speaker.
    2. If possible, try connecting the ethernet cable to a different port on the router.
    3. You can also try using a different ethernet cable to make sure that the cable is not faulty.
  • 1. Disconnect/unplug the product from the network cable. If dealing with a smartphone, forget the wi-fi on the phone. 2. Shut the router completely OFF. (do not reboot, you must turn it completely off) 3. Boot the router up and let it complete it's connection with everything, usually a few minutes. 4. Shut the router completely OFF, again. This is REALLY important. Before turning it off a second time, the router still has the product in it and is looking to connect to it. Shutting it off a second time allows the router to go through a complete power cycle without ever seeing the product, so it will remove it from its system. 5. Boot the router up, again, and let it complete it's connection with everything. 6. Now plug-in/turn on the product. The router should find the product and all should work. 7. If dealing with a smartphone, search for the wi-fi and reconnect to it. All should work after this.

  • Please do the following in this order…
    1. Go into the app and clear the Cache
    2. Uninstall the app from your device
    3. Forget or unpair the headphones/speaker from the Bluetooth list on your device
    4. Reboot the device/phone twice (this is an important step, as it ensures that the device has gone through an entire on/off cycle without ever seeing the app or Bluetooth pairing, so all remnants are removed from the phone)
    5. Reset the headphones/speaker
    6. Pair the headphone/speaker to your device
    7. Play some music to ensure a good Bluetooth connection
    8. Download and install the app
    9. Open the app and allow all permissions (app will not function without permissions)
    10. When the app opens, it should find your speaker and function properly
    Note: We cannot guarantee the use of our app when using Beta versions of Operating Systems.
    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.
  • 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.
