How to choose device that connects to Bluetooth headphones?

[Steve Swift]

I have a Galaxy S7 Edge, a Galaxy S2 Tab, and a pair of AKG K845BT Bluetooth headphones.
Bluetooth is always on for the S7 and usually turned on for the S2 Tab.

So, how can I choose which of the two devices will connect when I turn on the headphones?

The S7 seems nearly always to win the race, and so far I've had to turn off Bluetooth on the S7 if I want to connect the phones to the Tab S2.

One simple solution would be to buy another pair of AKG phones, and put one each in separate boxes labelled "S7" and "S2", but I'm hoping for a less expensive (and more technical) solution!

Another solution is to walk away from the S7 with the phones and S2 Tab and connect whilst the S7 is out of range. But this upsets my Gear S3 watch... and if I walk around too much, it upsets my dog.

Life's getting a bit too complicated.

Unfortunately that is up to the headphones. Some of them have a Primary and Secondary device to connect to if it supports dual connections, but most will try to connect to the last paired device.
