Theater Solutions B43GR Fully Wireless 240 Watt Rechargeable Battery Bluetooth Rock 4 Speaker Set Slate Grey Link Up to 99 Speakers Wirelessly

I purchased these speakers for my pool area because, according to the description, you could add up to 90 additional speakers. I didn’t need 90, but I could foresee adding 5 or perhaps 10 more. It would all depend on how much the neighbors annoyed me by constantly blasting Blake Shelton, which I consider an act of war. Unfortunately, these first four speakers had problems. The exterior shell is not terribly durable. One arrived chipped, which is ok; however, if you move them wrong or they tip over, they will bust to smithereens. I haven’t worked this hard trying to glue things back together since I karate kid kicked my momma’s good lamp back in the 80s. There are also sync issues. It’s difficult to sync all four speakers: it has to be done individually, and two or three will usually get an audio lag so it sounds like four drunks singing karaoke. Other than that, the battery life is decent. The sound quality when they are synced and operating properly is acceptable, and I guess they were still cheaper than having drunk people over to sing karaoke everyday. Overall though, I would not purchase again/will not be adding more. It’s just not worth the money.

I bought the set of four thinking I could use them around my hot tub all connected. Unfortunately we all have iPhones and it only allows you to connect to one of then at a time... I can only use one of my four speakers when I use them... kinda defeats the purpose of multiple speakers

Blue tooth is worthless. If you walk in front of it it will disconnect. If you have it playing from your phone and get a call it will disconnect. When it does you have to reset all the speakers. Get it together people and do some testing before you release products on the market.
