Just received these speakers yesterday. Charged the speakers up and then tried to pair them. I followed the instructions and it didn't work. Finally figured out that you hold the "MODE" button on the first speaker until it beeps. Then do the same on the second speaker. They paired together immediately. I was then able to pair the speaker to my phone.
The speakers do work well and do produce a stereo output. The bass response is not as much as I expected. The speakers aren't as loud as I had hoped. They sound a bit muffled.
I will keep these speakers to use as a background music source.
If you expect a lot you may want to put the money where it is needed. For the price, the ability to sync and have to good speakers to place on a deck or patio as a source of sound with stereo quality, these are great. We spend a lot of time on our deck and a single speaker was never quality sound to fill the area. When placing these two paired at opposite ends of the area, it provides full quality sound at a good volume. If you want a concert hall, the max volume will not satify, but for a entertaining area where you socialize, the volume and sound are worth the value. Extremely happy with them.
You will not believe the quality of the product and sound it pushes!! What a great item for a reasonable price. Outdoor and Solar charging are a huge bonus!!
I bought these on a whim for my patio and I love them! I staked them in two of my planters for surround sound. Perfect atmosphere for smores and BBQ's!
