Those are 2 very good choices.
I have the HP50's, have just had them for a couple months but they're well built and comfortable and good sounding. I've experienced zero "creaking". I project their durability as good or better than competitors. The most common problem in all headphones is an intermittent or broken connection between the cable and the driver. With the replaceable cables in the HP50, that won't be a problem.
I think headphones last a long damn time. I did get rid of a Grado SR60 after about 20 years, but I could have had it repaired.
Hey thanks for the response! That’s good to know that the cables are replaceable. I saw that they’re compatible with the V-Moda cables, is that what you would use?
