This article is a survey of high-end headphones from various manufacturers. We tested four models from a German company Ultrasone: the PROLine 650 ($299), 750 ($399) and2500 ($399), and the HFI-2200ULE ($299) — all variations on a theme. In addition, we reviewed Sennheiser’s HD650 ($549), AKG’s K 501 ($275), Grado’sSR325i ($295), and Shure’s E5c in-ear monitors ($499). Save for one, I found all of the models a pleasure and could happily live with most of them.
