Proper monitoring is a big issue in recording, whether it be checking for phase or listening for sibilance, monitoring is very important in any studio.
I find having a pair of headphones you know and trust to be a great cheat in a home studio environment or when working working at a foreign studio. The headphones can be your main reference if you get a good pair and learn to listen on them properly.
I personally use the AKG K240's and have for years, but here are a few engineers you may know and the headphones they prefer.
Sylvia Massy- Beyer-Dynamic DT770
Andrew Scheps- Sony MDR 7506
George Massenburg- Grado RS-1
Al Schmitt- AKG M50
Tony Maserati- Sennheiser HD600
