Koss Porta Pro Headphone

We've long been a big fan of these little open-back on-ear headphones. The Koss Porta Pro are perfect for listeners wanting a compact, great-sounding upgrade for portable or home use. We think the sound quality remains simply unmatched at this price.

The Koss Porta Pro easily fold into a convenient sturdy little bundle for travel. Headphone.com is a Koss-authorized dealer since 1995 so your purchase comes complete with the truly outstanding Koss LIFETIME warranty! 

These could still very well be our staff's favorite 'under-$50' headphone. In our Headphone.com review opinion, the Koss Porta Pro remain among the clearest, best detailed headphones suitable for any audio application. The superb 'bang for the buck' value of these unassuming but potent little headphones is simply off the chart.

The Koss Porta-Pro are just killer portable headphones at a very good price. Matter of fact, picky headphone aficionados have widely declared the Koss Porta Pros actually sound significantly better than some other headphones costing two or three times the price. If you have a tablet, smartphone, laptop computer or portable music player, these impressive small cans will perform wonderfully with all music genres.

And that incredible Koss manufacturer's lifetime warranty sure doesn't hurt any.  So get this: if a speaker driver heads south in a few years, or if one earpiece flakes out, or even if you accidentally drop and break 'em,  Koss will repair or replace these headphones free of charge as long as you keep your original 'Koss authorized dealer' purchase receipt, like the one you'll receive from us right here at Headphone.com. We have proudly been a Koss-authorized headphone vendor since our first day in business back in 1995 - or "The Dawn of Headphone Time," as we like to call it!

The Koss PortaPro 'Y'-type headphone cord connects at each earpiece via a short straight 4.5ft cable terminating to a 1/8' [3.5mm] 'mini' plug.  And, once again, let's hear it for that amazing Lifetime Koss warranty -- oooh, yeah!
