TEST: AKG K702

 What hasn't already been written, discussed and philosophized about headphones, as you can use them to get every conceivable gradation of quality, from the cruel "earphones" at iPod level that are barely tolerable for voice messages, to the almost perfect, three-dimensional sound reproduction thanks to dummy head recordings in terms of listening pleasure.

While the “healthy middle range of quality” on headphones is now almost exclusively used by instrumentalists in the studio for recording compositions, the gap in quality awareness among end users is becoming ever wider, similar to the income situation of Germans. While in one corner a conscious ear for frequencies is actually no longer present, the other corner takes a diametrical path towards maximum upgrades in terms of materials, sound behavior, impulse fidelity and wearing comfort.

A product from the second category is the AKG K702, a pair of headphones which, according to the manufacturer, are only equipped with the best components, but are also in the high-price segment with an impressive RRP of just under €400. The test will show whether the “Made In Austria” headphones, which are in the top weight class, the reference class, are worth their price.


Construction:

The K702 is a dynamic headphone designed with an open design. This means that despite using the headphones, the ambient noise can be heard to a large extent. The advantage lies in the communication with the “outside world”, which can be made much easier from a psychological and practical perspective than with closed systems.

The disadvantage of an open design, for example, is that a drummer will prefer closed headphones to record his parts due to the very high sound level of his instrument. In general you can say, “the louder your instrument, the more closed” (forgive me for this outrageous illustration).

The K702 has a commercially available shape, but what immediately catches the eye is, in addition to the elaborate headband construction, the oversized ear capsules, which should provide one or two surprises during the test.

In terms of technical data, the K702 is in the green zone in all categories, or even far beyond it. For example, a frequency response of 10 - 39,800 Hertz is more suitable for the “higher, faster, further” group and provides 50% of the human hearing with measurement data beyond the hearing threshold.

With a nominal impedance of 62 ohms, the K702 is pleasingly low and can therefore make full use of its sensitivity of 105 db SPL / V. Its weight of 235 g is moderate due to the complex construction, but can be described as light for the components it offers.

The headphones have the standard 6.3 mm jack plug, which can be converted into a 3.5 mm mini jack plug by simply unscrewing the top cover. Both connectors are gold-plated and thus ensure optimized signal flow.

An unusual but very useful feature is the headphones' detachable cable. Finally, when storing or transporting the product, you can store or transport the cable separately and you don't always have to resort to the terrible "I'll wrap you around an earpiece" or the infamous "knot solution with pre-programmed cable break". Since I've been working with headphones, the cable problem has always annoyed me, so you can't praise such a comparatively simple feature enough!

A very complex “cable solution” leads to optimal placement of the headphones on the head. The padded leather strap is optimally placed on the head using two threads on each side using a return system on the two guide rails and thus adapts to almost any head shape.


Practice:

During the first use, the large ear capsules are immediately noticeable in terms of wearing comfort. On the one hand, you have the very pleasant effect that, due to the fact that the entire ear is free under the capsule without any pressure point, there is no blood congestion in the auricle, even after long periods of use. Who doesn't know the annoying itching that occurs after a while with almost every pair of headphones due to the difficult blood supply to the outer ear.

The unpleasant side effect, however, is that the ear capsules (at least with my face shape) now rest on the cheekbones due to their size and exert a slight pressure from the outside in. Not overly strong, but at least enough to give my brain a brief “what’s that” effect. However, this is a purely subjective impression that cannot be generalized. Every face is different, so an individual comparison must be made. This is probably just a matter of habit.

In terms of sound, the K702, like many devices in the higher quality range, initially comes across as a bit “brittle” or “angular”. Where did that come from? Well, a reference device must be able to do one thing above all else: the neutral reproduction of a signal without the oh-so-popular “whitewashing effect”.

While the majority of “instrumentalist headphones” with their soft, over-present bass, slightly lowered high-mids and defused high-frequency range are primarily intended to provide a “feel-good” effect for the artist and an associated increase in performance, a reference Product to face the unvarnished truth and reproduce every dented frequency curve in all its “tonal ugliness”.

Therefore, any experienced headphone user will at first listen to the K702 have a slight over-presence in the mid to high mid range. However, this is primarily due to the frequencies being reproduced as linearly as possible and is initially interpreted as “harsh” or “sharp” due to the hypersensitivity of human hearing in the midrange.

In addition, the light neodymium magnets have a faster response and do not “swallow up” the high frequency range as quickly as their sometimes slower relatives, which also contributes to the present sound. If you know how to integrate these behaviors into your listening behavior, the experienced sound engineer/sound engineer will find the K702 to be a highly impulse-fidelity headphone that is not disturbed by high sound pressure and unexpected level peaks.


Conclusion:

The AKG K702 has fulfilled its claim to be a reference class! Processing, construction and detailed solutions are at the highest level and ensure a long service life and practical handling.

If you have become familiar with the sonic characteristics of the K702, or if you have already sensitized yourself to the point where you know how to interpret the frequency curve and the impulse behavior tonally correctly, you have a tool with the K702 The top class is available, which fulfills its function to the fullest extent and with the highest quality!
