Connect Early 2015 Macbook pro to TWO HDMI monitors via Thunderbolt or USB
Assuming you mean the 13-inch version and not the 15-inch one.

According to EveryMac.com "This model supports a simultaneous maximum resolution up to 3840x2160 on two external displays via Thunderbolt 2."

So as long as that max resolution is OK with you all you need is the appropriate cabling. And the one you found is for USB-C/Thunderbolt-3. Which is wrong for your Mac. 

You need something similar to this. Note I just snagged the first product on an Amazon search for "Thunderbolt 2 to HDMI adapter." I have no idea if that is a quality product or not.
