Sennheiser's Momentum headphones may be expensive, but for the price, you get what Inner Fidelity calls "the best sealed headphone for general purpose uses," a set of headphones that are "very good looking, very good sounding, have excellent isolation, are easily driven from portable players, and are supremely comfortable." Wired agrees, calling the leather-clad cans "downright sexy," and saying they sound "phenomenally sweet" and that "sonically, they certainly deliver on the expectations set by the $350 price tag." PC Mag also likes the Momentums, calling them a "victory of design and audio performance," and citing their "excellent audio performance, with no distortion at top volumes." Want something negative, to help you avoid spending $350 on these? Inner Fidelity calls them "slightly small," which could be a problem if you've got "larger than average ears." So, try them on, and if they fit (and you can afford them), buy them.
