Koss Porta Pro Utility On-Ear Headphones, Stealth Grey Interchangeable Cord

Owned these many years ago and remember them being an excellent sounding headphone. They were not in the best of condition after years of use so decided to purchase a new pair. My memory did not fail me. The Porta Pro is still a fantastic sounding headphone for this price. In fact, I would compare them to models costing 4 times as much. One caveat is you have to like “on the ear” open sounding headphones. If you prefer an isolated “between your ears” sound these are not for you. Any loud outside noise will probably be noticeable. I prefer the “outside of your head” sound that these produce. The music floats just outside your ears much like listening to room speakers. The frequency range seems to be quite accurate. Even though the earpieces rest on the ears and not around, the bass is punchy, well defined, and musical with no added boom. The midrange has great detail and the higher frequencies may be a bit rolled off, but are very easy on the ears and do not produce audio fatigue. The Porta Pros, despite the low price are more than adequate for focused, critical listening. They are light and not sturdily built and should be handled with reasonable care. Highly recommended.

WoW, a no brainer purchase. Koss Porta Pro Utility. these are amazing, the best sound and comfort, got the extra cable with the mic for phone calls. wore for hours. wow, calls are crystal clear, music is crazy amazing very dynamic range with super punchy bass, vocals are amazing. Not audiophile quality but the most fun since the original old school Sony walkman headphone, remember the first listen? it was wow.

I have had these for all of 3 hours, so take it for what it is. first impression. as other reviewers commented. the wires out of the cans seem thin and weak. the sound lacks "full" midrange and highs. plenty of bass. I was surprised at the cable. thought it was 3.5mm to 3.5 mm. its not. one end of the cable is 2.5mm and the other end is 3.5 mm. this was important to me because I have a lot of 3.5 to 3.5 mm audio cables of all lengths laying around and was planning on swapping for a longer cable. I have had KOSS Porta Pro's in the past and I sort of remember them being made better, and sounding better, which is why I bought these.

Same great Porta pro sound with a fun stealth colorway and better cables

Great sound as always, but... • The cable is thin and feels flimsy • The utility connector feels stiff and requires lots of pressure to fit. • The construction uses weaker plastic (the transparent bits between the temple cushions and earpads), which cracked after about 2 months of daily use. • The band doesn't adjust smoothly like in earlier models. I legitimately have purchased over 20 pairs of Porta Pro headphones and, for whatever reason, this specific part of the set is particularly weak, which is uncharacteristic of this line of headphones. While it has other good qualities, I can't justify buying it at all if it's going to critically fail within 2 months of just wearing them. Get an earlier model, or cannibalize an earlier-model headset and pop these speakers into it.

I have owned 2 previous Koss headphones, the original wired one from 2013-2018 and the wireless bluetooth from 2018-2023. They both eventually succumbed to basic wear and tear from the wires, and started losing sound quality, but I was very happy with the length of time I had used them. This brings me to this product. Firstly, while I would have preferred to have the original iconic light blue earpieces, black frame and silver band design, I was not opposed to the new redesign. The headband was a black metal, the light blue ear pieces were strangely replaced with blue left and red right earpieces, and the plastic frames that connected the ear pieces to the head band was now a translucent black plastic. In total these 3 changes were strange to me, I specifically didn't understand why the two earpieces were not symmetrical in color, either both red or both blue. On the upside, the one change I liked was the flattened cable, it made it very clear when the cables were twisted in the wrong direction, as this was a problem in my previous 2 Koss headphones; they would get tangled in ways I could not easily undo, because the cables would rotate around themselves and bend in a way would only be undone if untwisted in the correct direction. I later learned that it was much easier to just pop off the headphones and let them unravel. The biggest knock against these headphones is the fact that after a month of daily use, the left earpiece snapped off the headband. I was just unfolding the earpiece when it just snapped cleanly in two. The plastic seems much weaker than the older models I've had, as they still are very strong and have not bending or warping. A smaller complaint would be the way the headbands extend and contract, sometimes the little plastic squares that hold the two metal bands in place get stuck, and the headphones are unable to contract, as I typically extend them to the maximum distance, then shorten them to fit my head. Instead they just get stuck and I have to spend a minute fiddling with the plastic piece to get it unstuck from the metal band so it can contract properly. Overall I do not suggest this product, return to one of the older models that use more durable plastic and have less loose parts that risk getting stuck. If a newer koss was able to keep the old headphone design, but retain the new flattened cables, that would be my ideal iteration of this product.

I love Koss headphones. These look silly. They feel good or comfortable, I wore them in public Hannafords if you know that reference. They sound great with 3.5mm or aux. Koss's Utility series allows balance cables and sound witch makes the product budget premium.

I have owned Koss headphones since the mid 70's...never found anything that would surpass my original Pro4AA's or my Pro4AAA's. My 2nd generation Pro4S I purchased a few months ago were more comfortable than the predecessors due to cup shape.and weight. The new Porta Pro Utility are the most comfortable yet being On Ear vs Over Ear but the sound is Perfect! Very little deep bass loss due to On Ear and extremely light! I wish I'd bought them earlier. I especially like the Modular design using the optional USB-C cable with the integral DAC circuit for my Samsung A54 phone which has no separate headphone jack! Well Done KOSS!!!

fue un regalo para mi mejor amigo, increíble calidad de sonido, se percibe todo y de manera muy limpia, comodos y super lindos. como un suuuuper plus sirven de accesorio y complemento para un buen outfit.

They look amazing and super retro in a great fashionable way… My critique is that they are very fragile above the ear piece. And are uncomfortable do to the thin sponge lining.

E um ótimo fone, tem um grave bastante reforçado e no geral o som é agradável. Sinto falta de um app desenvolvido pela Koss para equalizar o som e ter uma experiencia mais equilibrada quando uso no celular.

The plastic around the earphones broke in 5 months, could never fit on my head and I had to purchase something else to replace it altogether. But I guess there isn't much to demand outta $60.

There's a reason these headphones are legendary. The sound signature is mostly balanced and fun to listen. Highly recommend.
