We've long been a gigantic 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 true Koss-authorized dealer so your purchase comes complete with their outstanding 100% manufacturer's lifetime warranty!

These could just still be our favorite '$50-and-under' headphone. 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, WalkMan 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; If you accidentally break 'em or if the speaker drivers decide head south in a few years, Koss will repair or replace the headphones as long as you keep the original 'Koss authorized dealer' receipt -- like the one you'll get from HeadRoom!

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 -- oooh, yeah!

nice work headphone
Posted by wobbowobbo from seattle, wa on 2013-12-23

Recommend Product: Yes
Pros: good sound, comfortable all day long
Cons: seemingly cheap construction

i got these headphones to replace my superlux 668b, which did not allow me to hear my co-workers.

sound: pleasant, full
comfort: excellent
look: retro in design, my co-workers made fun of me. also much more compact than i thought they would be - which is good.
durability: looks cheap, but actually it has a very clever design and is not as flimsy as it appearance - also the koss warranty will fix any damage.

overall - i am very happy with these as my work headphones and the cost was extremely reasonable - i don't really want to leave my more expensive headphones at work.

Excellent Design / Good Sound
Posted by Samuel J from Chicago, IL on 2013-01-14

Recommend Product: Yes
Pros: Design, Price, Warranty, Fun
Cons: Bass-Heavy Sound, Style

I bought the PortaPro's as a replacement for my KSC-75's. I gave those away to a friend and missed them immediately. I loved the sound from the KSC-75's, but wasn't a fan of the clip-on design. The PP's design is truly outstanding! The way they fold, the tension adjustment, angled plug, And the fact that they don't interfere with my glasses is something that no other headphone does. The style on the other hand is somewhat of a drawback. However, I like the fact that no one would want to steal them in that respect ;)

The osund is much more bass-heavy than the KSC-75's. I'm still tinkering with my player's EQ to dial them in, though. I have burned them in before using them, so I think that once I create a good EQ preset, I'll be looking forward to a long life with the PP's. With a lifetime warranty, I can be patient with dialing them in. If only Sennheiser did that...
