We do not recommend using Mogees with bluetooth speakers. Connecting bluetooth speakers to your phone adds latency (a time delay) of up to a few seconds.
This means that when you play you do not hear the resulting sound until much later, which kind of ruins the experience of playing music live.
For this reason we recommend using Mogees with wired speakers or headphones. Many bluetooth speakers have a line in/aux in 3.5mm slot so you can connect a 3.5mm cable from your mogees to this slot to work.
