Released on: 01/01/1984

The good: The Koss PortaPro Headphones combine a functional design with excellent 3D sound and a low price tag.

The bad: Hair gets caught in the collapsible band; some people will dislike the '80s aesthetic.

The bottom line: Koss hit a home run with the PortaPros. Love or hate the design, there's no denying the sound quality here: they're the ideal companion for mobile audiophiles and home theater enthusiasts.

With so many funky headphone designs flooding the market right now, it's getting harder and harder to choose which one to buy. Instead of showing you the latest snazzy set of cans, we're taking you back in time to showcase the Koss PortaPros. These headphones are the ultimate in retro chic and are guaranteed to get a few comments, but you won't hear them thanks to the beautiful symphony of sound flooding your ears. For $50, we're hard-pressed to find another set that rivals their sound quality and quirky design.

The first thing you'll notice about the PortaPros is that they look like something from the 1980s. That's because they are--Koss released these exact headphones in 1984 and they became so popular that Koss hasn't changed a thing for 23 years. These headphones retain the same design both internally and externally. The earcups are secured to your head by a thin steel headband that adjusts with two sliders that tighten and loosen the tension. Once you have them in place, the PortaPros are actually very comfortable--they're featherweight and additional cushions on top of the ear pads prevent the headset from slipping. The comfort level is taken a step further with what Koss calls their "Comfort Zone." This feature has three mechanical settings that let you adjust the tension of the earpiece against your head. The downside is that there's no way to lock the headband in place and the sliders like to get caught in your hair as you take them on and off. This also becomes a problem when you want to rest the headphones around your neck--the band immediately tightens up and practically strangles you.

On the plus side, the PortaPros also fold up and clip together for relatively convenient storage. The overall design of the PortaPros is hit or miss. Not everyone will be keen on the design, but we actually love the way the headphones look. The light blue touches and extended hardware conjure fond memories of a time when Marty McFly, Lobot, and Tron ruled the world, and who are we to argue with a 23-year dedicated following?

Looks aside, the real reason why the PortaPros still remain classic (albeit underappreciated) is because of their fantastic sound quality. Just keep in mind that these came out decades before studio-quality sound-isolating headphones became available to the consumer market, so they definitely won't block out the majority of ambient noise. They also started to leak sound at the one-third mark on our iPod's volume bar, but we're not surprised given their open-ear design, just be sure not to crank it up too high around your neighbors. However, aside from that, we have very few complaints.

In our audio test, we compared the PortaPros with another set of foldable cans, Sennheiser's PX100 miniheadphones. We had good things to say about the PX100, but were ultimately unsatisfied with the lack of treble range. In contrast, the PortaPros simply blew us away with their range and ability to maintain quality at a high volume. We pumped several songs in a wide variety of genres through the headphones and each one produced a focused sound in the midrange with detailed resolution in the highs and surprisingly thick, head-shaking bass. Our MP3 of "Fatalist Palmistry" by Why? sounds much better with the PortaPros as well, clearly separating each instrument with equal balance while maintaining sonic realism. According to Koss, the sound output is handled by "neodymium iron boron rare earth magnet structures" that provide a 15-25,000Hz frequency range, which certainly sounds like random vendor jargon, but truth is that for the sub-$50 range, the Koss PortaPros are the headphones to beat.

If all that isn't enough to convince you to snatch up a pair, consider that Koss offers a "no questions asked" lifetime warranty on the PortaPros. If anything happens to them during normal use, Koss will send you a new pair for the cost of shipping ($6.00). Now, that's music to our ears.

I registered with Cnet just to tell you how good these are

by dave.i on May 13, 2008

Pros: Incredibly comfortable, GREAT sound!

Cons: Only con is if you don't dig the 80s aesthetic and can't get used to it (I did).

Summary: Cnet has never really steered me wrong when it comes to reviews but for some reason I was still extremely skeptical of these headphones. I'm just as old as the design for these little guys (we're both born in 1984) so the looks definitely threw me for a loop to say the least. Staring at the pictures online is a completely different experience to view and hold them in person. Online they look quirky, bigger, and awkward. In person, the style feels almost ultra-modern, clean, and beautiful. Before I saw these in person I was definitely excited about the idea of the sound quality (not to mention warranty) of these 'phones but the looks definitely had me worried. When they arrived in the mail I fell in love. These headphones sound just as great as the video review here on Cnet suggests. I was extremely surprised to find that the range separation and warmth of these headphones rival that of some Sony studio-quality full-sized headphones that I used to listen to in the past. Without these even being broken in yet, I can honestly say these headphones are THE BEST BANG FOR YOUR BUCK you can find. No question about it. None. I've been through Denon, Sony, Sennheiser, Ultimate Ears, Shure, and some others (which all sound great depending on the model and headphone style) but none equal in value. These can be used for any application, really. They're cheap, give in and buy these, you won't be disappointed (assuming you realize these aren't noise canceling and won't give you superpowers).

there's a reason they're still around after 20 yrs

Summary: I got my 1st pair in 1988 with a Sony Discman (which was $300 back then). 20 years later that Discman has been replaced by an 8GB iPod nano which holds 15x as much music (at CD bitrates - more like 50x at typical mp3 rates) is ~1/50th the size, ~1/100th the weight, lasts 2x as long on a charge and cost 1/2 as much.

20 years later I'm STILL listening on PortaPro - 'nuff said!

my only complaint is that the cord's kind of short which isn't a problem with the iPod but I have to use an extension cable to plug into my computer at work. one warning too: to really hear the quality these things are capable of you need to stick to lossless transfers off CDs - aac (iTunes) or low-bit mp3s are like hooking a VCR up to a 1080p HDTV (i.e. garbage in/garbage out) though this will be true of any higher-end headphones.

Superb sound and comfortable to wear

by citizen_can on December 7, 2008

Pros: I loved my three pair of Sennheiser PX100's scattered about the house but decided to give the PortaPros a try. I still love the PX100's but find myself using the PortaPros most of the time, especially for the bass response and comfort.

Cons: The hair-snagging snafu is real but was solved through high-tech application of one piece of Scotch tape to hold the top slider in place. This might not work for those needing to pack and carry, but it works well for me.

Summary: As noted, the bottom line is these small wonders sound superb! I had my doubts when ordering them, but for $35 at Amazon, I figured I couldn't go wrong. ...

Summary: As noted, the bottom line is these small wonders sound superb! I had my doubts when ordering them, but for $35 at Amazon, I figured I couldn't go wrong. From the first listen, I knew I had winners. I'm no audiophile, but I expect excellent sound, and these phones delivered. Once the hair-pulling problem was solved, I noticed they are the most comfortable headphones I've ever worn. They sit so lightly I almost don't notice them at all. I love the retro look and find the cutaway design just above the pads makes it easier to don them and to get left-ear/right-ear placement perfect every time. They are so small they don't look nearly so clunky as they appear in the pictures. The article and commenters have said enough about the sound that I have nothing to add. But I do plan to add one or more two more PortaPros s to my collection. BTW, the only reason I didn't give them a full 5-star rating is because of the hair-pulling thing. I still have a bald spot from that first depilation. (j/k) This seems like a defect Koss could somehow correct.

No better than the better looking Koss UR40 Headphones.

Pros: Full range, very natural and present sound. As comfortable for long-listening stints as they are appealing sonically.

Cons: Hokey looking. Not the most durable construction.

Summary: Wish C-Net would review the Koss UR-40's, a foldable, more professional set of phones that sounds at least as good as the PortaPros. Neither one is made to hold up under day-in/day out use. So keep Koss' lifetime guarantee offer close by.

Summary: Sound is better then in my $80 v-moda, paid $36 on eBay including delivery. For all of you with hair pinch problem, cut your hair or go bold and buy this amazing item it so worth it.
I?ll still prefer v-moda for everyday use because of the size, but at home, office and on the bike Koss is much more comfortable.

Hard to beat the sound for the price

by honuman32 on January 24, 2009

Pros: Fantastic, clear sound

Cons: Design is dated.
Sound carries past the headphones which can be annoying to neighbors.
The storage pouch that comes with the headphones is a little tight when trying to get the cans inside.

Summary: I have another pair of headphones which ran around the $120 range and I think the Koss portapros are noticeably better. I can hear greater depth in the music with ...

Summary: I have another pair of headphones which ran around the $120 range and I think the Koss portapros are noticeably better. I can hear greater depth in the music with excellent seperation between instruments. The sound is bigger while retaining clarity as compared to any other lower end cost headphone I've heard. I like the way the headphones breakdown for storage with a clip to lock it together. Although I'd like to someday buy a higher end headset when I can afford to, for everyday use and more, this is the best headphone set I've ever had especially at the price.

Bose on-ear headphones vs. Koss Porta-Pros

by Nlimited on January 3, 2009

Pros: *AFFORDABLE* at 39.99 with a lifetime warranty and excellent sound quality that has kept up with over two decades of new audio technology. Very light and compact. Unparalleled sound range for sub-$100 headphones.

Cons: Does not cancel out sound (like all non-noise canceling headphones, this pair still allows the listener to hear what's going on around him/her)

Summary: i've been looking for a very good set of headphones for a long time. Like most consumers at first, i was sold on the Bose reputation for producing excellent-sounding ...

Summary: i've been looking for a very good set of headphones for a long time. Like most consumers at first, i was sold on the Bose reputation for producing excellent-sounding products and assumed that their products were the best on the market. After listening to the Bose on-ear headphones in the store, I bought them for a little over $170. I went home and listened to them and simply could not accept that the sound justified the 170-dollar pricetag, even after 2 weeks of listening to them. A thing to remember from this experience is that anyone buying headphones should first listen to them *with their own music*. The Bose demo's are nothing like the music that most people listen to (the man on the Bose demos with the deep voice and the rich instrumental background will sound completely different from Coldplay's Viva La Vida). i'm not saying Bose on-ears are terrible. i'm simply saying that if you're looking for the best sound quality for the best price, Koss porta-pros take top honors in that category. i'll go as far as saying that the Koss porta-pros sound equal-to if not better* than the Bose on-ears. the only edge that Bose on-ears have over Koss porta-pros are their soft cushions that help block out surrounding sound. At 39.99 i decided that i could live without the soft Bose cushions.

If you're looking for a pair of headphones with excellent sound quality that's only exceeded by its price value, then get out there and pick up the Porta-Pros!

For $50...simply unbeatable!

by bburn--2008 on December 12, 2008

Pros: 80's Design? That is why they're so awesome! Now forget about style for a minute, please. These babies sound amazing and are very comfortable. Mine were bought in1991 and still sound phenomenal and a lot better then new ones of the same price range.

Cons: I wish they was a wireless version of these :)

Summary: For budget headphones you won't be disappointed.
