Got this a few days ago and really like the sound “quality”. However, the sound “volume” is an issue. At the lowest level, it’s quite loud. Use in public will be limited.
I bought 2 sets of these Bluetooth speakers (4 speakers) because they were offered as a points reward on a credit card. I was intrigued by the multiple speakers feature. Connecting to my smartphone to the main speaker is easy. I tried following the directions in step 3 of (TWS), but I had more success pressing the "Press/Play/Pause" button to connect the additional speakers. The sound quality is good, but the sound consistency (not volume) is not. The additional speakers sound like they go silent every few milliseconds...sounds choppy. I'll still use them in my backyard. Also a nice feature would be a 3.5 mm audio out. I would be able to connect the main speaker to my stereo and use the additional speakers in sync.
