If you only have two of the same models (like both are Flip 6, doesn't matter if one is the TL and the other one is a CS serial number model) it is about the same loudness as when you would connect 2 Flip 6s in PartyBoost mode, only with the added benefit of stereo sound which can be more immersive than only PartyBoost. PartyBoost only really makes sense when you connect more than 2 speakers or you have one Flip 5 and one Flip 6 which wouldn't work in Stereo mode. PartyBoost with multiple speakers has definitely more bass and loudness but the stereo effect is not there, but almost there when placed around the room :D
Do they sound better in Stereo mode vs Party boost? Thanks in advance
