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

Thanks for your feedback. This is a common occurrence when receiving a call while your phone is connected to Bluetooth.

Good Sound but could use more base
Bought this to have a little bigger option over the Charge. I own a Flip, Charge, Extreme and the Boom Box. I will be honest expected a little more out of this. It has good clear sound but could definitely benefit from having the base boost added like Boom Box has.

Xtreme upgrade!
This is a whole new level…. I bring it in my car with me sometimes 🤣 the bass is so intense, it’s super crisp with the custom equalizer in the app.. I previously had the Charge 4, and this blows it outta the water!..

High quality high price
I feel that I'm neutral about the product I like the features but I don't like the over all value. It's a good speaker however the price tag is a little steep. I'm glad it came with a warranty. I would recommend it if price is not a consideration.

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.

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
