I don’t have the translation but I believe they are hollow. You supposed to be a little better sounding than the i500. I like the shape of the i500 better and the clean look on the back. The i525 cavity reminds me of the g700 with that different piece near the heel. Again, don’t like it, love the smooth look of the back of the i500. I saw an actual i525 picture face on and the toe looks almost pointy. Not appealing to me. They’re not hard to hit, they’re like a Taylormade p790.
They’ll be out soon but it’ll take you 8 months to get a set😁😁
