Compare Guitar strings. Barely notice the difference!

The video starts off with Hannabach's high tension strings and in the middle at different points The D’Addario's normal tension take over.
They are very similar but the D’Addario has a slightly more open brighter sound, and the Hannabach's has a warmer round sound. I was surprised to hear that the Hannabach's were not as bright being they were high tension.
