Described as being neutral monitor headphones. Lowest price I've seen them at. Very comfortable earpads. The coupon works for pretty much everything else on their store except for the B400 Earphones.

I had the jaycar equivalent of these headphones about 4 years ago (brainwavz, jaycar, some other higher end brand I can't remember are all from the same factory). Really liked them for sound quality and isolation, but not for longevity - the plastic frame that connects the ear-cups onto the headband is quite fragile, and broke after about 12 months.
I since upgraded to both BeyerDynamic Custom One Pro, and Audio-Technica AD900X (one for home, one for work) - both are an upgrade in sound quality and sturdiness - the Custom One Pro are basically unbreakable.
Get this if $100 is the best you can afford - get something more robust if you have more money ($200 or so).
