I eventually got a cheap headset, which is still useable. It really just uses clamping force to passively reduce the drone of small plane noises. For short durations, this headset is adequate and gets the job done. However, on longer flights, the headset becomes a little uncomfortable. I'll apologize in advance to my future passengers...you get to use my old headset.
With my re-introduction back into flying, I wanted something that actively reduced the mind-numbing whoosh and hum of small airplane flying. That meant I wanted an active noise reduction (ANR) headset. There are many to choose from. Of course I did my homework and sought review after review on the latest and greatest ANR headsets. One thing I learned with my musical endeavour was to buy the best you could afford. If you don't, you'll always want the next model up. So, I went for the top of the line.

Bose A20. It is expensive, but it has remarkable noise reduction capabilities. It was amazing how 'quiet' the cabin was after activating the noise cancellation. My instructor's voice came in crystal clear and any calls that came in were crystal clear as well. Amazing! This headset also has an external input for music or GPS. This headset also comes with bluetooth for a connection to the cell phone. And another positive is that this headset has 1/3 the clamping force as other passive headsets. In other words, they are very comfortable. If it weren't for the remarkable noise cancellation, you would forget you were wearing them. I haven't tried out the music input or the bluetooth functionality yet, but the active noise cancellation is worth the price. After all, how much is your hearing worth?
If you are in the market for a new headset, I highly recommend the Bose A20s.
