I love my Klipsch HP 3. Don't use them often but they sound great. I had some Grado RS 2e and they were excellent, I ended up giving them to my son in law and he uses them all the time
My first pair was over 40 years ago, AKG k240... I still have them. I had some nice Beyerdynamic too. Currently my only pair I use is the HP 3. I'm driving them with the excellent Quicksilver headphone amp.
