I needed to get a new set of headphones for listening to music at work on my computer and also as a second set for my HiFi setup at home, Teac amp and Stanton turntable. I was impressed with the frequency response 16 - 24000, and the price. Overall I am very happy with the headphones, especially the quality of sound. They work well with everything from Spoken Word to Classical to Rock and Electro-jazz. The driver response is very quick and their is no distortion unless it's intentional as on ZZ Top's Fuzzbox Voodoo. The Acoustic seals are very comfortable once you figure out that the headband should be positioned slightly further back on the head than normal. There is very little outside noise heard once you wear these headphones. The swivel feature on the each of the earpads allows you to queue or set up the tracks. generally I am very happy with these headphones.
