The Audiophiles Sound-IsolatingTM Earphones.

Developed by the audio experts at Shure, purveyors of professional concert equipment for more than eight decades, these are the high-fidelity in-ear earphones that isolate the listener from intrusive background noise, blocking sounds naturally using a precise-fit earpiece instead of the artificial noise-cancelling technology found in many larger headphones. To ensure the proper fit in any sized ear, the earphones come with a pair of disposable foam sleeves, a pair of triple flange sleeves, three pairs of flex sleeves (small, medium, large), and three pairs of soft-flex sleeves (small, medium, large). The flex sleeves contour to the ear for complete sound isolation and a secure fit; additional personalization can be completed by ordering cus tom-made sleeves from a hearing specialist. The miniature speakers generate powerful and faithful audio reproduction using high-definition drivers with Tuned Port technology, a design which improves air flow around the driver for extended bass response and audiophile-quality sound from CDs, MP3s, video games, and movies. These lightweight earphones have a 56" cord, and include a zip-up carrying case and a volume-level control to adjust fixed-volume sources such as airline audio jacks. Specify Black or White. (1 oz.)
