Review headphones Ostry KC09 — hot hit of the season

In fact, this review was supposed to leave early, and not even one month. Confuse me with yourself Ostry, suddenly announced the reduction of prices (which is always good) and changing the packaging. While I was waiting for, what they will change in the box, it turned out that to change and they do not intend to, so the text didn’t even have to change, but he went out with some delay, however, the earphones themselves is also only made it to the stores.

I think, no exaggeration to say that the model Ostry KC06 and KC06A became a legend in countries of the former USSR. The headphones quickly became popular, combining good design, good sound quality and affordable price. Further experiments into the field of liners special popularity did not use (although the model was quite OK), so the developers went back to the form factor IEM.

Model KC09 was originally scheduled for release at a price of $ 200, and even in that segment it was very competitive, but the insidious Ostry decided to dump the full and reduced price tag 2 times, turning a potentially good model to hit (as I was zampoleri, eh?).

Well, judge for yourself: high quality made headphones, sound from Ostry and replacement wires for the price of most Chinese hybrids from second-tier manufacturers is not this a dream?

Packing and delivery

If I was the company handing out design awards, and I would KC09 a couple, and one for the following year. In the packaging of these headphones Ostry were able to demonstrate simultaneously style and restraint. Box sealed in plastic, made from simple recycled cardboard, her half hold on the magnets and makes the metal plate with the company logo. Everything inside is divided into three sections, which are: headphones, interchangeable tips and cable. Tips included three types:

  • Normal odnoplanovye silicone, three sizes
  • Nozzles with filter, medium size
  • The attachment of “sticky” silicone, two sizes

Incidentally, the latter is very good, they provide a very tight fit headphones with perfect fit and therefore improve the sound insulation and sound headphones.

Design and comfortable wearing

Needless to say, but Ostry made a model, unlike other headphones. Metal housings with chrome design have an unusual form, perhaps best to send her pictures. Outer panel (faceplate) decorated leather, a black and brown paste (in my opinion, black is better, but it’s a matter of taste). Headphones full of interesting design finds like marking channels with small color “sickle”. Of course, all of the nine high quality built and customized, as the bulk of the metal adds a sense of reliability.

Headphones are primarily designed for behind the ear wear, to put their cable down, although it is not very convenient. KC09 small size that provides a comfortable fit even for the owners of small ears. Soundproofing is a little above average, especially if somewhere pick them dvuhventsovye nozzle.

Wire models are made interchangeable, are used MMCX-connectors of good quality (judging by the strength of the fixation). The MMCX connectors, and decorated in keeping with the headphones, although because of the shape of them a bit inconvenient to take with your fingers to mute (but correctly — they should not be vain here and there to pull). Wire made in fabric braid, it is of medium hardness, so really he could do with a ear-hook memory foam — sometimes it falls from the top of the ears, although I have this is rare. The wire does not harden in the cold and a little confused, the microphone effect is not strong, behind-the-ear fit allows you to make it almost “no”.

Sound

To listen following equipment was used.

  • Yulong DA9 and Resonessence Labs Concero HP in the role of DAC and amplifier
  • Apple MacBook Pro Retina 2016 as the source
  • Fidelia in the role of player
  • Lotoo PAW Gold, theBit OPUS#2 and iBasso DX200 and the role of other portable players
  • Recording high-resolution Lossless-formats (Dr. Chesky have The Ultimate Headphone Demonstration Disc and others)

Before listening headphones were heated for 48 hours.

Speaking “in General”, the sound of nines develops those ideas that are loved by the customers in 06A — a departure from the traditional emphasis on bass and treble in favor of a slightly dark sound, with emphasis on the lower half of the range. Of course, this does not mean that these headphones are deprived of RF (grief sufferers from the “sawing”), and does not mean that they have the bass dominates as in a typical beshenyh models. Moreover, KC09 make a significant step forward in high-speed characteristics, which is beneficial to the overall perception of their submission.

The bass here is very typical of high-quality dynamic transducer. It is not dry, not trying to play super fast and give increased hlestkost, but the lack of resolution here to not complain. Bass in these headphones is accented, and the amount of the emphasis can be changed with the help of tips, choosing a level to suit your tastes. I stopped on a variant with the filter, as with it the rise of bass for me reaches the perfect size: enough to create a realistic effect weight, but not enough to prevail over the rest of the frequency range.

MIDs can also be called perfectly balanced, KC09 — it’s not headphones with a focus on microcontrast, they serve a material whole, but, of course, there is no feeling of lack of detail. “Overboard” are basically the flaws in the recording and other similar problems, so neautiful anything of value will not lose but rather gain. The ability to listen not the best quality recording without focus problems is a very significant advantage. Surprisingly well headphones build an imaginary scene, sometimes even a little “pojazdowa” her wide. It sounds not always of course, but in combination with accent bass very effectively. The depth of an imaginary scene — about average, but the study plans are very good. The nature of the instruments transmitted normal for this price range, and the vocalists have a small (very small) of “boost” to emotion.

The high-frequency range was also a bit adjusted compared to the previous model of the company. While maintaining the General permit and the development plans for the tweeter (not ideal, but for the price good), KC09 slightly reduced the aggressiveness of the attacks on HF that benefited their naturalness and perception. Overall, despite the good resolution and the lack of attempts to “pin down” the treble, they sound comfortable and not straining my ear (well at least mine).

As models in similar price range very much, but the endless time I, unfortunately, do not have section comparisons will be quite brief.

MEEAudio P1. Another model, which won massive popularity. Of course, the price P1 above (although Massdrop version is close in price tag to KC09), but we here compare the sound. And this parameter there is a fundamental difference in approaches. P1 is more neutral, with slightly more resolution and more extended treble, while KC09 offer more emotions and more relaxed sound, especially on poor quality tracks.

FiiO F9. Another competitor at the price range. There is a difference in the sound directly attributable to the design: F9 is the hybrids, so they have a better resolution on MF and HF, but in HF they have a noticeable peak, and overall they sound “dry land” at the expense of the reinforcing emitters. KC09 more “continuous” in nature and offer exchange bit of contrast to the comfort and integrity of perception.

Whizzer A15 Pro. Despite the dynamic design, the sound “Missery” is also reminiscent of the hybrid model with the emphasis on bass and treble (not the Pro version, the similarity is even more). Compared to KC09, they offer a more scathing bass with a little less physicality and more accentuated treble with a more dynamic attack. MIDs have A15 a little more laid by the wayside, but overall a drop better.

Simgot EN700 Pro. Headphones from Simgot is another small step in the direction of the “relaxed” sound: a little shegendeu attack, slightly less resolution, slightly above unity, in General one step from an audiophile listening to “spare parts” to the whole music perception.

Compatibility

The headphones have a “correct” impedance and sensitivity — no noise with powerful players, but it is quite “” modern smartphones. Although, of course, the latter does not reveal the full potential of this model to the fullest. The optimal source for it is the players initial-middle segment or so.

Genre KC09 very versatile, and their manner of presentation makes the headphones a good option even for poor quality a priori, recorded a variety of styles like the strand. The quality of the recording they are very tolerant, somewhere in the 6 points on a 10-point scale of “waywardness”.

Traditionally, a few tracks as example

Sonny Rollins — St. Thomas. The most famous song in the repertoire of the famous musician, and generally widely known jazz thing for fans of “neshannock” jazz from KC09 sounds great. Slightly enlarged scene adds to the realism of the track, and beautiful bass-based tools is very “tangible”, which is also perceived very effectively.

Clutch — Firebirds!. I don’t know who coined this fashion, to write a modern “hard” dirty and called it “vintage sound” (in the 70s on the contrary fought it as best I could), but this is a harmful belief interferes very many good teams, including Clutch. Fortunately, KC09 good and with such a track — enough bass, but without busting, a bold midrange, but realistic, normal RF, without emphasis — yield “what should be”.

David Bowie — Suffragette City. A fine example from 1972, also bears the imprint of the recording technology of the time, many headphones becoming a fragmented mess of weak bass and crisp treble. I think not reveal a big secret if I say that KC09 it’s all very well and in a balanced way, starting from vocals and ending with all the nuances of HF, who often lose other headphones.

Insights

Headphones that had all the chances of success at the original price, but sold for half the cost, is not this a dream? Especially if everything is in order with sound, design and ergonomics, and with it Ostry never had a problem.
