Model overview based on user reviews  
The Koss Porta Pro headphones are renowned for their excellent sound quality, offering a rich bass and clear mids and highs. They are lightweight, foldable, and have a stylish retro design that appeals to many users. However, the headphones are often criticized for their fragile wire and foam ear pads, which tend to wear out over time. Many users emphasize the importance of purchasing the original product due to the prevalence of fakes, which lack the sound quality of the genuine model. Despite some durability issues, the headphones are praised for their comfort and portability, making them a popular choice for music lovers who appreciate a good price-quality ratio. They are particularly recommended for use with players rather than phones, and while they offer good sound insulation, they may not be ideal for noisy environments like subways. Overall, the Koss Porta Pro is considered a classic choice for those seeking quality sound in a portable format.

Definitely take it. For even three times the price you won't find anything better.

An excellent model not only for its money, but also among much more expensive headphones. The sound quality - my respect, will give you a light on an apple wireless airpc for the cost of my monthly salary. The volume of sound is also decent. The headphones are very light, when worn correctly, they do not press at all and feel as comfortable as possible. You need to understand that these are open-type headphones, which means the sound insulation is appropriate (although it depends on who, I personally liked this design, it helps me hear what is happening on the street).
As I described above, the sound is excellent, with a good balance of frequencies, price, lightness and powerful design - all this for only 3-4k rubles. I especially recommend it to fans of rock and metal of all genres, because... the entire spectrum of sound is transmitted so that fire.
At first, you need to get used to how to wear them correctly, but this stops being a disadvantage once you understand how it's done. Also, the headphones aren't too sturdy; they survived two falls when folded, but I'm not sure about when they're unfolded (I broke a similar pair of my sister's as a kid). The open-back design means that people standing close by will hear the music. The cable stiffens at +5°C, so handle them carefully outside.

There seem to be many drawbacks, but it's a small price to pay for this sound and experience. Even if something happens to these, I will order another pair of Koss Porta Pro.

For their price, the headphones outperform competitors by a head, if not two.

Weight (very light)
Transportability (easily foldable)
Quality materials (foam, plastic, and metal)
Comfort (after a week of wearing, you don't feel them on you)
Plug (gold plating increases the service life)
Cord (soft and flexible)
Case (pouch that feels nice to the touch)
The headband starts to seize up over time
Ear pads wear out quickly (within 6 months, with daily use for many hours)
Foam (soft material) absorbs sweat very well, especially in summer
The headband pulls out hair when worn (after 2 years)
Wire wear (standard for all wired headphones), break at bend, etc.
The wire (becomes hard and inflexible in cold weather, and wears out faster than the plug)

Headphones — a legend.
I've been using them for a very long time, I can't remember exactly when I bought them, I think it's been at least 10 years… Of course, during this time, I've had to do some minor repairs: I replaced the cable because over the years, it lost its flexibility and became "stiff"; I fixed one of the drivers, but that damage was my fault - I dropped and stepped on it; I also replaced the ear pads, since they are foam and wore out after several years of active use. I really like the design; they are lightweight, with a thin headband and additional foam pads around the temples. This is very important to me because I wear glasses, and finding headphones of this type that don't press on the temple arms or head in general was very challenging—I tried many. I have no complaints about the sound. When listening to heavy music at high volume, they don't rattle; all sounds are very clean and clear, and the bass is excellent.
Quality sound, weight and compactness.
If you do not carefully adjust the temples, it can “chew” the hair.

Legendary oldies making the younger generation

The legendary brand Koss is considered to be the inventors of stereo headphones and the creators of the technology of projecting sound directly into the ear, which laid the foundation for "earbuds" and "droplets". For more than half a century, the company has been producing products that are popular with music lovers around the world.

Structural features and thirty years of design

The Koss Porta Pro model is hugely popular due to its quality sound, affordable price and stylish design, which has hardly changed since 1984. The design of the headphones is foldable with a spring-loaded metal headband, which allows it to automatically adjust and be conveniently assembled for transportation. Of interest is also the suspension of the speakers that changes the angle of inclination, which provides ease of use. In general, the design makes it clear that the device is ready to work “for wear and tear”, only foam rubber ear pads cause doubts, which will still have to be changed over time. Headphones are distinguished from modern models by a solid thick wire, but connecting it to each cup in order to maintain sound qualities can be inconvenient.

The headphones come with a stylish case, but you can only find it in the original version. By the way, one of the most global problems of the model was an incredible number of low-quality fakes, so if you want to touch the legend, you will have to choose very carefully.

rock and roll sound

For the younger generation, the sound can cause a lot of controversy, but looking ahead, it’s worth saying that in its price range, the playback quality of the model leaves no competitors.

The bass sound deserves special attention, it is warm and velvety, slightly reminiscent of a tube one. Low frequencies are very competitive, despite the consignment status, the "failure" of the bass is not felt, but rather, on the contrary, the composition acquires volume and "airiness". The mids and highs are also well tuned, but to be picky, the high frequencies, especially in electronic and pop music, are a little plastic, and at high volumes, the bass line begins to dominate and the sound gets a little “dirty”. Usually, a similar effect is always noticeable when using headphones with devices that have a powerful amplifier.

In general, the model is not very picky about the sound source, and even the average impedance (60 Ohm) is not a hindrance to "friendship" with elite and powerful players. Incidentally, the best bass control is achieved by pairing the headphones with low output impedance players.

Model Modification:
  • Model Porta Pro KTC — mobile phone headset with remote control
  • Model Porta Pro SpeakEasy — computer headset with built-in microphone and a longer 2.4 m cable
