Shure has introduced a new pair of earphones and two new pairs of headphones at the 2011 NAMM Show in Anaheim, CA. The SE215 Sound Isolating Earphone features a single Dynamic MicroDriver, a detachable cable, and includes three pairs of black sleeves, three pairs of soft flex sleeves, and a carrying case. It will be available in clear or translucent black and is expected to sell for around $100. The SRH550DJ Professional DJ Headphones feature 50mm drivers for extended bass, a super-aural design for better isolation, an adjustable, collapsible headband, an included 6.3mm adapter and an included carrying bag. Finally, the SRH940 Professional Reference Headphones promise accurate frequency response, a collapsible, lightweight design, a padded headband, and include a 6.3mm adapter, two detachable cables—straight and coiled—a replacement set of velour ear pads, and a zippered hard carrying case. Shure’s SRH550DJ and SRH940 headphones are expected to sell for $100 and $300, respectively; all three new models will be available this Spring. [via Engadget]
