Studio/Closed Ear Style.. I found a more economical set that are patterned after Sony and Senn's.. But, as long as you don't throw them against the wall (Sony cans, tend to lost connections and wear out on the ear cushions), I have bought a neat little light weight pair of ALPHA-LINE / 26799's for around $30 bucks... 20 hz to 20,000 hz (K-Mart had them in stock here in the prairie)....
