CoolTechZone.com has posted a review on the Grado RS2 Headphones

Last week, we reviewed Grado's RS1 pair of headphones, which was the most expensive pair we've ever tested. Not only that, but it's one of the most expensive pairs in the market currently. Although the RS1 had handcrafted mahogany wooden chamber, leather headband and excellent audio quality, we determined the price tag to be too much at $695.00 for it to be a reasonable pair for anyone but a professional. Even the audiophiles will find the price tag to be too much to fulfill their obsession with high quality audio.
