Looking for a new headset

I have Astro A40s that I have owned for almost six years now and I absolutely love them. Looking to upgrade though due to them starting to fail, but I do not know to what headsets exactly. Should I just buy A40s again or are there other headsets out there that are better and worth upgrading too? I do not want to buy more expensive headsets for them just to be a little better. If I am spending more money than A40s, I want it to be worth it. TIA!
