Eatfun Air Pro 3- Very Tiny/Echo-y on Macbook Air

Hi,

Just received Air Pro 3 today.  I set it up on my iPhone and it sounds great! I followed instructions to set up to two devices simulataneously so I could also connect to my  Macbook Air. Audio sounds tiny/echo-y  on my laptop  no matter the source, but it's fine on the phone.

Any advice? Would it be better to just connect separately instead of have it connect to both? Is this just a feature- that it's not great on computers?

Thanks!
