With impedance, power handling, and sensitivity all tuned for professional audio devices, the Shure SRH440 is the perfect set of reference headphones for the road. Rounding out the appeal, the collapsible construction makes packing the set a breeze, the detachable coiled cable gives you length to move and an option to replace, and the solid plastic casing adds durability to the entire device. The vendor supplying this drop is offering a version originally intended for sale overseas, so if you see a few unknown characters on the box, pay them no mind.
