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.

The Partybox 310 cannot connect to other Partybox models such as the Partybox 100, 200, or 300 via TWS connection. The Partybox 310 can only connect to another Partybox 310 with TWS connection. 

Unlike the Partybox 200 and 300, the 310 does not feature RCA connections. 

Please Note however, that if you have multiple different Partybox models, connection via Daisy Chain using the Aux In/Out or RCA In/Out connections is possible. To connect a Partybox 300 with a Partybox 310 for example, you would need an RCA to Aux cable or an adapter. The Partybox 100 and Partybox On-The-Go only have Aux in connections, so this would need to be at the end of the Daisy Chain.

You can connect two of the same Partybox models (e.g. 2 x Partybox 310, or 2 x Partybox 100) together in TWS Mode by pressing and holding the Bluetooth button on both speakers for 5 seconds, or by pressing the dedicated TWS buttons on the rear panels of both speakers on the Partybox 110, 310 and 710. It is possible to pair two different Partybox models together using a wired connection (e.g. 1 x Partybox 310 and 1 x Partybox 100). It is also possible to pair two Partybox different models wirelessly in Party mode, however this is only possible with the newer Partybox models - the Partybox 110, 310 and 710. The Partybox 200 & 300 can be paired in TWS mode as they are the same model apart from the presence of a battery in the Partybox 300. If you connect an instrument or microphone to one Partybox speaker while using TWS, the instrument or microphone connected to one speaker will be reproduced by this speaker alone. You will not hear the instrument or microphone in both speakers. If it is necessary to have instruments reproduced by two or more PartyBox speakers, it is possible to use an RCA or aux cable – connected from the RCA, aux or daisy chain outputs on the speaker that the instrument or microphone is connected to, wired to the RCA, aux or daisy chain input of the secondary speaker. Alternatively a small mixing console can be used - connecting audio sources to this mixer and sending the mixed audio signal to the speakers with a wired connection.
