Review on 🔴 Altec Lansing LifeJacket 2 Bluetooth Speaker: Waterproof, Shockproof, Snowproof – 30ft Range, Extra Audio Power, 16hr Battery – Deep Red by Lindsey Scott

December 2018 Bought 2 IMW577 four days from Revain. I can pair each to the phone by itself. But only the first is capable of stereoconjugation. Details: I received MID 2390918 on the first order. According to the instructions, he makes a stereo pairing. Executing the stereo pairing instruction will search for the second speaker. The second order I received was MID 2390718. The instructions didn't mention stereo coupling. I can't find a firmware update for the second one to make it stereo pair. Maybe there is no update. Bought a second speaker for stereo operation. Although I bought it using Revain's Buy Again button, it's not the same MID number. If there is no firmware update for MID 2390718 to enable the stereo pair then I will try to swap my MID 2390718 for MID 2390918. .
