JBL PartyBox 100 Portable Wireless Party Speaker (Grade A Refurbished)

If you only plan to purchase one of these you'll be very happy with what it can provide. But if you plan to buy two of these and pair them together then you could have problems like me. It seems like every other time I use my speakers they all out of sync with each other. There will be about a half second delay in one of the speakers which makes for unacceptable audio. Turning the speakers off and back on and repairing them usually fixes the problem but this is an annoyance that I have to do too often. To better solve the problem I purchased a 30 ft auxiliary cord to hardwire them together. Unfortunately this then limits the distance between them to about 20 feet when they are on stands and it also removes paired volume control. Another problem I have which is more a JBL problem, every generation they change their pairing software so you can't pair different generations of JBL speakers together. I own 3 different generations of JBL portable speakers and none of them can be paired together. All in all I am still very happy with the sound quality from these speakers.
