Foreword
The Sound of KOSS, which has always focused on headset manufacturing KOSS, has been active in the headset circle since its inception. As a veteran American headset company, its product sales are also quite impressive, among the best. The KOSS PP product has been on the market since 1984 and has undergone decades of testing, and has not been discontinued so far. It can be considered as one of the most classic products in the earphone history.
KOSS PP is an abbreviation of Porta Pro. It was originally a classic design style of blue and black. It is deeply loved by music enthusiasts, especially those who have begun to burn. The positioning is not high-end, but it is aimed at the Volkswagen Junior High School or ordinary headphone users. The positioning is very accurate. It is characterized by a typical low-frequency explosive, good sense of balance, giving the overall hearing full and rich, sound impact, especially good at popular and rock or Gothic style songs.
In recent years, KOSS PP has launched a white version of KOSS PP WHITE in order to cater to the aesthetics of the Chinese people. I have been fortunate enough to have received this experience from IT168 testers. Today, I will give you a talk about the performance of this white PP!
First sight
From the packaging, we can see that this is a black and white style of headphones, although classic heritage, but the color has changed after a more fresh feeling. IT168 tester's LOGO must be out of the sun Kazakhstan, thanks to every activity of the tester.
Although it is an American brand, but the place of production is still known to you in China, and like the big-name Sennheiser, KOSS is also authorized in the domestic Jin Yi International (the old firers can ignore, as long as you see the Jin Yi International standard, it must be Is a genuine country line Kazakhstan), and the vast majority of headphones, KOSS PP also enjoy a one-year warranty. Headphone sensitivity 101dB is not too high, impedance 60 ohms also shows that this is a not very easy to drive (push) headphones, such as large impedance earbuds, small mp3 or cell phone and other front-end is simply not move , and now look again, now the flagship mobile phone loading HiFi chip thrust is also quite big Kazakhstan, should be sufficient to deal with.
Compared with Xiaomi’s notebook, Li Xie’s notebooks are small in size. If the music lovers haven’t seen PP, they will not think that they have big headphones. They look like the packaging of a small ear plug.
Hey, this is not a small earplug, oh, don't look at the bag, but inside the classic PP. Presumably, you must be amazed at its portability. That's right. Compared with the Sennheiser PX100, which is another classic burning weapon at the same level, PP's portability is even stronger than that of the PX100!
In addition, if you do not want to carry a hard headset package, KOSS also presented a soft leather headset earphones, feel it is relatively high grade. Do not worry about the comparison of products, the iron triangle headset is also a lot of enthusiasts like to buy the brand, the old iron will also send headphones bag, but the old iron head of the ordinary headphone bag compared with the KOSS leather headset bag, dwarfed.
detail
And blue and black version of the appearance is "a hair", "say it used to be good" This sentence is not a bit slippery feeling, ha ha, but the friends used classic PP for the product appearance can be skipped directly what. Prota Pro's logo is printed directly on the headphone unit. There are L and R logos on the ears, and the white and black circles don't have a good taste.
The girl can't wait to put on a try, but even for grown-ups, she will feel a bit overwhelmed after wearing it for a long time.
This is the same problem as Sennheiser's PX100. Both of them are designed for strong portability (too many fold-and-bend designs) that cause the headset to burn and have a chuck. How to do it?
If you are using a PX100, you can only endure it or listen to it for a while. For PP, there are more adjustment options. Everyone can see a “comfort zone†at the horizontal connection above the headset unit. The sign of "" represents comfort adjustment. There are three levels of adjustment from Firm to Light.
There are such adjustment buttons on the left and right ears. Just press the arm to the middle or the LIGHT side. The headphone unit will automatically tilt outwards. You can observe the following picture.
It can be seen that the earphone unit was originally moved closer to the inside. After comfort adjustment, the earphone unit becomes directly parallel to the LIGHT end. Through such adjustment, the sense of compression of the earphone collet can be effectively reduced.
Whether it is an adult or a child at home, it can be adjusted back and forth to the best condition, which greatly improves the comfort of wearing for a long time. However, the author reminds you here that in order to protect your hearing, personal advice is to take it off every half hour.
If you want to return from the LIGHT end to the FIRM side, it's easier to think about it if you just go straight to the FIRM side. You just need to fold the headset unit and pop it back, so if we pack it in a headset bag When you use it again next time, remember to re-adjust it.
Sound quality analysis
As we mentioned before, KOSS PP is a headset for positioning low-end entry. The classic is that the sound quality tends to be low-frequency. As a headset that Jordan and Zhou Jielu both endorsed, their low frequency can use a powerful one. Words to describe, even listen to some R & B songs will feel small and heady! The low frequency is very large, but its bass is not as fast as the mid-range headphones such as the Sennheiser PX200, so it gives people a feeling that the bass is thick and fleshy. The direct consequence of the unacceptable bass is that this headset is not suitable for listening to some drums. Sound, fortunately, strong sense of envelopment, or won the likes of early burning white. Listening to pop, naturally it goes without saying that pop music doesn't have as many basses as R&B or Rock Bass, and beyond songs are more than adequate, and a “Gray Track†is enough to make you tearful.
When you listen to T-ara's Lovey Dovey, it's just low-frequency bursting. The cheerful girl pop plus humming and the pulsing BASS rhythm make you like this combination quickly. The author's favorite is the Japanese version of this song. " Funny than funny than Europe ~ Europe ~ Europe ~ Europe ~, haha, wall crack recommended Oh ~
Conclusion
KOSS PP with its classic styling (Chow's favorite) and the world's best low-frequency, popular music for decades, so far in the earpiece early burning circle enduring, Sennheiser PX series has been contending with, but after all failed to PK KOSS PP.
How much of the old burned gold fungus was burned with black fungus, how many old burned into the poison camp (IMP3) burned down three generations, I have already had fever, but memorable classics. The phrase "don't expect extravagantly forever, only care about having once owned" represents the helplessness of many people. Now they pick up the PP and think back to the time when they were young and young, the time wiped out youth, but music can awaken our young heart.
By using the tester's white PP to commemorate the classic KOSS PP, let's keep a young heart and pay tribute to our youthful years!
