Partybox 300 delayed sound on TWS


I have two Partybox 300 speakers and when I connect them in TWS mode, after a while the sound is delayed ... I have to turn off the player or the music and wait a few seconds for it to resync.
Both speakers have firmware 151110.
How can I solve this rather annoying problem?

    I have the same issue.
    When are inTWS after some time (could be half an hour, or only few minutes) they desync, as one is playing with a Delay. This is only fixable if i power off Bluetooth or if I stop the music.

    I have the same issue. Bought 2x 300s at the beginning of May and been an unlistenable nightmare from day one.
    30 email exchanges with customer and tech support and no solution as yet.
    Has anyone had any luck with this massive problem yet?
    I am in discussions with Harman but it's all very slow and I am running out of patience with it. Best part of £800 for a high end audio set up that does not work..
