Re: Headphones vs Gear
Get the gear if you have a choice, and save your lunch money and eventually get a pair of the Sony MDR-7506's. Those are industry standard and you can get a pair for $99. Nice thing too is that they're so ubiquitous in the industry that many places have replacement ear foam pieces to replace them when they wear out - a nice feature extending your investment. They really are that good.
If you want isolation earphones, the GK Ultraphones are Peltor shooter's headphones outfitted with parts from Sony MDR-7506's. But those are $300, and worth it.
