Koss Porta Pro KTC Headphone

Koss has upgraded their famous Porta Pro headphones with a 3-button remote for Apple iPhone, iPad, and iPhone devices.  We've long been a big fan of these little open-back 'earpad' (on-ear) style headphones for listeners wanting a compact, good-sounding upgrade for portable and mobile use. The sound remains simply unmatched at this price and the Porta Pro conveniently fold into a compact and sturdy little bundle for storage or transport. HeadRoom is a Koss-authorized dealer so your purchase comes complete with their outstanding 100% manufacturer's lifetime warranty!

What We Think:
The Koss Porta-Pro are a killer-sounding portable headphone at a very strong price. Matter of fact, picky headphone afficionados universally declare the Koss can actually sound better than some mobile headphone designs costing twice the price. If you have an iPod, iPad, MP3 player, laptop/PC computer, tabletop radio, portable CD/DVD/MiniDisc player, or other portable audio device, these little cans will perform wonderfully for all music genres. The Porta-Pro likely remain amongst the clearest-sounding & best musically detailed mobile headphones suitable for all your portable audio needs. Moreover, that sweet Koss manufacturer's lifetime warranty sure doesn't hurt any. The long-running Koss Porta-Pro product design is pretty unique in the category: Two small pads on the sides of the Porta-Pro headband allow the headphones to rest simultaneously on your ears and cushion on the sides of the head, giving these headphones an extremely secure feel in active applications like during heavy exercise or gym work. The earpieces collapse inward and the headband ingeniously curls up to clip at each end, allowing the cans to fold down quite small for storage or travel. The Porta-Pro's 'Y'-type cord is connected at each earpiece by a short straight-type 4.5ft cable and the cord terminates to a 1/8' (3.5mm) mini-plug jack. A full-size 1/4' plug adapter is handily included in the Koss package. Lifetime Koss warranty -- ooh, yeah!
