Koss porta PRO has been on the market for over 25 years and during that time the model has not lost its fans. People buy the headphones, break them after a couple of years and buy the same model again. What attracts them? The convenience of the headband and ear cushions, the good sound of music tracks and movies, as well as the ability to combine headphones with various transmission devices.
Design and ergonomics
When you take the Koss porta PRO out of the box, you can be surprised to feel their lightness and as if they are unsteady. But this looseness and looseness is deceptive. In fact, the headphones can please you with durability and practicality. The flimsiness and the feeling of fragility is due to the fact that all the elements of the device are not fixed firmly, retain mobility.
The mobility allows the headband to fit anatomically on any head diameter. The height of the headband is adjusted by advancing two plastic adjusters along the metal headband. In the middle of the regulators meet - at the maximum possible width of the headband.
Users note that it is desirable to adjust the height of the headband before you put the headphones on your head. Otherwise, there is a risk of catching your hair and ripping a good chunk out when removing the headphones or adjusting the desired width of the arc.
The 7 best headphones for sports
Headphones with open cups and over-ear cushions don't provide a high degree of noise isolation. The hum of the train will drown out any melody on the subway. But on a busy street in these headphones you can hear a car coming from behind, a cyclist approaching.
Other design features:
- the possibility of compact folding;
- symmetrical wire to both headphones;
- L"-shaped plug with more than 90 degrees of rotation for a comfortable fit.
A distinctive feature of Koss headphones is the presence of foam ear cushions on the cups and special temple stops. In the area of the stops there are also external regulators, which help you to set the force "to press" the cups to your ears.
That is how Koss porta PRO differs from Sporta model of the same manufacturer. The Sporta model has no regulator, maybe that is why they are considered to have worse sound.
The speakers in the cushions are attached to the cups movably, scrolling on the hinges. This allows you to comfortably put the headphones to the ears of any size.
Owners note that even with prolonged use of headphones there is no discomfort in the ears, head skin does not sweat, headband does not rub the head and does not put pressure on the crown. Ergonomics are excellent, there are only a few complaints from users who wear the headphones on their head for more than 4 hours.
Compact folding is another plus of these headphones. The cups are rotated on the hinges and folded inward. This opens the hooks with which the ends of the headband are connected.
This prevents arbitrary opening of the headphones. Some difficulties arise with the wires, which become stiffer in the cold. In order not to tear them, it is better not to use the device in -20.
The kit also includes a "leather" case, which is tightened with ties. Although it looks very small, folded headphones just fit into it.
Since the case is soft, it can easily be placed in a bag or pocket. Moreover, given the normal durability of headphones, you can not worry that somewhere they will be pressed by books or bag will not be neatly placed, thrown.
Available Functions
The functionality of the headphones is minimal, their task is just to reproduce sound.
But they can work with a variety of devices:
- push-button phones;
- smartphones based on Android, iOS or Windows Phone;
- music players;
- laptops and PCs.
Owners of headphones note that they are good for listening to audiobooks, as they clearly and distinctly reproduce human speech. It is also convenient to use the device for listening to podcasts on the way to work or on a walk.
For sports, the Koss porta PRO is not very suitable. According to users, symmetrical cables are very disturbing when moving. Hands get tangled in them, sometimes accidentally pulling the cable, you can tear the headphones from your head.
Positive feedback on the device are cyclists and joggers, who appreciate the dynamics of melodies and sound detail.
There are also rave reviews from movie buffs, who appreciate the headphones for the successful fit. Even after several hours of using the device, there is no headache, no feeling of heaviness.
The only disadvantage is that you can't watch movies in a room where someone is sleeping, because the low noise insulation lets all the sounds out.
Sound playback
The sound is almost perfect. And not only for headphones in the price category of 2,000 - 3,000 rubles. Users are actively comparing the quality of melody playback with monitor headphones, wondering how small overhead "ears" can compete with professional equipment.
Some experts point out that it's probably because of the "floating" speaker, which is not firmly attached to the cup.
Be that as it may, feedback from headphone owners about the sound quality is mostly positive:
- "Velvety bass. I like listening to pop music, rap. The tops are not very distinguishable, but the middle is lively. These are great for watching movies, they reproduce special effects clearly. But you can't watch videos on the metro, the noise bothers me.
- "I would like to point out the sound quality as an advantage. The mids and lows are quite well-drawn. The upper frequencies are a bit lacking, but the scene is still great.
- "Bass is good, midrange and treble are also good. For home or office - perfect, can be used for listening to voice messages, but you'll have to buy a microphone separately."
- "For walks in the woods, at home and running are good. High sensitivity speakers allow you to use them even with older phones. Perfectly recreates a wide scene and quite decent vocals. Bass has to be adjusted in the equalizer.
Lows, by the way, the headphones are not so good to admire them. The reason is the lack of noise isolation. To feel the power and depth of rock compositions, it is better to buy full-size monitor headphones like Technics. But Koss is more of an everyday option for unpretentious music lovers.
Conclusions
Poor noise isolation, so often mentioned by users, is a feature of the Koss porta PRO design. And, if you want to enjoy great music in everyday life, you should put up with the background "behind you".
These headphones are optimal for people who like hiking and biking, as well as for music lovers who prefer to go to school and work to their favorite tunes. Foam earmuffs are not particularly durable, but a spare set of ear cushions can be purchased additionally.
