as always JBL does not disappoint at the same price point as the JBL boombox this partybox is a great deal, I've had the product for a couple of months now and I enjoy it very much, it's easy to carry around so I can take a practically anywhere, it is now my go-to when I'm going to the beach or what I'm having picnic at the park or what I'm just having a party at the house it does the job, I recommend this product to anyone who loves nice salmon music for various occasions... and also thank you zZounds for the great customer service all the years that I've been with you guys

"Volymen problem"

Overall: 5 out of 5 stars
(see rating details)
Speaker sounds great but experiencing volume issues using my iPad or iPhone 8 Plus. You can adjust the volume at first with both the iPhone 8 Plus and my new ipad, but volume controls on both apple devices quit working after awhile and not sure why. And at times the volume will either just go way up, or way down by itself. Read another review, and someone else was experiencing the same exact thing. Does anyone have an idea what could b causing this?

"I LOVE THE SOUND, But"

Sound quality is excellent! However I had to return item because the power up button completely quit working.. after a few days it decided to work again.. but then when i started using it, the volume using bluetooth via iphone 8+ would randomly go down, sometimes completely as well as randomly go up and sometimes completely.. my replacement is unfortunately doing the same thing! Its very annoying. Its not the phone because i got a new phone . Now its possible it could be an issue with apples But i never had this issue with my other JBL Bluetooth speakers... i really do not want to return this for the second time.. but its very disappointing. If there is a remedy for this i would live to know it. So far i have not been able to find anything out. My service with zZounds has been fantastic however.. ive also purchased a pioneer controller through them. .
