I used one of the clubs ASA headsets for most of my training, then bought a Sennheiser passive one. The Sennheiser was okay for a bit, but now I am flying quite a bit more during my hour building and also wanting to protect my ears and stop getting the "headset headache", so I bought a set of Bose A20's. They are amazing, and I wish I'd bought them to start with.
Lightspeeds are also very good, don't think you'll be disappointed with either.
