Product title: Philips HP550 Full Size Foldable Headphones (Discontinued by Manufacturer)
Product description: Lightweight, foldable and pliable, these Philips headphones are designed for an all-around great listening experience. 40mm neodymium speakers with 500mW of output fill your ears with a rich, dynamic sound. Long, 5-ft. cable plugs into portable CD players and hi-fi sets. Features a side piece for cable winding and storage. Silvertone with blue and black accents. No. SBCHP550. Imported., Think you have to shell out big bucks for quality headphones? Think again. This set from Philips offers comfort for long listening sessions, a closed-ear design that keeps unwanted noise from interfering with your music, pivoting earcups that help the headset fold to coat-pocket size, and--happiest of all--clear, well-balanced sound with surprisingly good bass., Sure, you'll get better sound with more expensive headphones: cleaner bass, more refined treble, less fatiguing midrange. But to get that, you'd have to pay several times what these puppies will run you; we dare say they're the best headphones out there for under $100., And the fact is, even headphones that give you some of the more "expensive" qualities mentioned above don't do so with the same innate sense of rightness imparted by the HP550s. With this set, the spirit of the music came across from every disc we played, from the nuanced Crouching Tiger, Hidden Dragon soundtrack to Oregon 's delicate acoustic textures and U2's hard-hitting All That You Can't Leave Behind ., The padded earcups are comfortable and well suited for either home or portable listening. They don't block all noise, so you may still want to consider a noise-canceling headphone for airplane travel. But the HP550's combination of comfort, convenience, sound quality, and affordability is unrivaled in our experience. Personally cherished and highly recommended. --Michael Mikesell, Pros: Amazingly good sound for the price Clear, tight bass response Closed-ear design superb for portable use Comfortable ear cushions Compact size Lightweight Fluorescent, high-tech sheen, Cons: Limited high-frequency extension (despite a strong HF measurement) They make you look like one of the Jetsons
