Re ....what could be improved

About the only 'gripe' I have ......Bit disappointing .... I have a set of Bluetooth wireless bud headphones and cant pair with SX  ( see page 104. side notes in manual ) 
Bluetooth function works fine to import sound   .... ie... pairing tracks from my external MP3 /mobile. but not export
As I see also according to the manual external speakers are not able to be connected.

Ok. But can't you use a headphone jack to Bluetooth converter?

Maybe there is something available Fred .... i did have a standard 'wire free'  set of phones a while ago which had a plug in sender from keyboard socket , but these were not great as there was a slight delay. i will have a look around for a solution.
if not ....its not a big deal to stick with my wired phones.

I suspect bluetooth headphones will also have a delay and that is probably the reason why Yamaha does not support them.
