Model Number (M/N) Product information The product information is located under the 

weather door of your speaker (in the compartment where the charging port is located). Warranty 

 

How long is my battery supposed to last and how long does it take to recharge? 

 

Playtime 

 

Overall playtime depends on how you use your Ultimate Ears Speaker, with things like the type 
of music and volume level all affecting the overall playtime. However, when played at roughly 
mid-volume, you can expect you can expect up to the listed hours of playtime from one full 
charge. 

 

Charging 

 

Using the USB cable provided, and a standard USB port (e.g. Laptop) it will take approximately 
5 hrs. 30 mins to recharge your Ultimate Ears Speaker to 100%. Wonderboom can also be 
charged with most USB chargers and times will be faster depending on the output of the USB 
charger you use. 

 

Never charge your Ultimate Ears Speaker if the micro-USB port, charging cable or connectors 
are wet, dirty or damaged. Always charge your speaker with a clean, dry micro-USB connector. 
If you think your cable or connector has been compromised in any way by water or other 
contaminants, do not use it to charge your speaker. Contact us for a replacement cable. 

 

 

Why won’t my Bluetooth device connect to my WONDERBOOM? 

 

If your Bluetooth device won’t connect to your WONDERBOOM, try the following: 

 

 

Make sure your speaker is turned on 

 

Make sure your device is paired with your speaker and Bluetooth is active 

 

Place your Bluetooth device closer to the speaker – it might be out of range 

 

Move your Bluetooth device and speaker away from other wireless sources – you could 
be experiencing interference 

 

Turn your ULTIMATE EARS speaker off, and then back on again 

 

If you have multiple ULTIMATE EARS speakers, make sure you’re connected to the 
correct one 

 

Your ULTIMATE EARS speaker can store up to 8 devices in memory and keep three 
active connections (two for BOOM) devices at a time -- make sure you don’t already 
have three devices connected 

 

NOTE: If this is the first time you’re pairing a device with your speaker, you don’t need 
to press the Bluetooth connection button. It comes out of the box ready to pair.
