[quote=fjetter;693153]I would recommend getting a good GA headset and worry about a jet compatible headset when you get hired to fly that equipment. If you're a CFI now you know how uncomfortable a traditional DC esque headset can get after a long day. I would recommend either the Bose or Lightspeed Zulu. I recently purchased a Bose earlier this year using their 0% financing ($83 a month/12months). By far the best investment I have made.

I reitterate fjetter's post.

For pistons, invest the money, its worth it over time.
Once your operating turbine platforms, clarity aloft and others mentioned are something you can't go wrong with.
However, look here as well. I understand these are impressive. Best of luck.
