Great sound for hang outs
I love it. Great sound. This was a present given to me for my birthday, but I was the one who chose it. My celebration was running a 5k and then have some BBQ, this speaker was just perfect because we enjoyed great loud music for my birthday celebration.

Sometimes when it's ringing the Bluetooth connection is cut off and it is interrupted many times in a row

Great sound, occasional connection problems
The sound from this speaker is incredible. Strong bass and clarity. Connection is an issue at times, however, particularly when trying to connect with the Xtreme 3 through Partyboost. Otherwise, a solid speaker

I recently purchased the extreme 4 and I loved the device but this only lasted a day for some reason I couldn’t to Bluetooth I tried everything reset tried connecting to a new device and followed a bunch of tutorials on how to fix this issue and nothing the Bluetooth on this device wouldn’t connect but for the day it lasted it was great definitely what I was looking for perfect for my everyday use couldn’t ask for anything better. Well I decided to return the device and by the way it was a rebuilt/refurbished device looked brand new and worked great for that day it was just the Bluetooth connectivity issue but in the works of getting another one

A great Portable Speaker
I bought the JBL Xtreme 4 to replace a Bose Soundlink that was heading to retirement. I saved money by choosing a refurbished unit. It arrived in a couple of days and looked brand new. What really impressed me was the ease of use and the wonderful quality. Great sound and has all the volume you need for the use I intended. The battery is long lasting and in the far distant future, is easily replaceable. You will not regret this purchase.
