Can I play music from my Samsung galaxy a5 to 2 separate Bluetooth speakers at the same time?

I can play media to 1 device and calls to the 2nd but not media to both simultaneously. Can this be done with this model of handset?

No, Bluetooth is one-to-one-per-function. So you can havew one device for media and another device for phone, but you can't have 2 devices for media. (That doesn't mean that you can't have stereo headphones, but that's one device, a headphone Bluetooth receiver.) It's not the device, it's the way Bluetooth works.
