AKG K612PRO Open-Back Over-Ear Premium Reference Studio Headphones

Product Information

One can expect the elastic bands for regulating the headband height to loose it’s tension after a few years. La presión que ejencen los muelles de acero y su remachado, hacen que la diadema se "magulle" y se deforme por falta de consistencia. Mala longevidad le auguro a esta parte del auricular. Obvious features such as the self-adjusting real leather headband, aluminum arches and solid rivets not only provide a lightweight, maximum comfort fit, but also reinforce the quality AKG has provided to studio engineers for decades. The ‘sharp’ and detailed but otherwise neutral tonal character is visible. Also the resonance are visible. Even though the horizontal part is somewhat sloping the bass extension is very good. Just not at the desired level.

It is very wide, but I really enjoy that aspect of it because I can hear everything going on. In other words, the K702 absolutely never sounds muddy or congested in any way. Bass: Bass when the headphone has good synergy is very textured and detailed, extends unusually deep for an open headphone and has a large and powerful presence with plenty of impact. It’s also great for pretty much all genres across the board but does excel with lighter compositions.Desktops, Monitors, Pen drives, Hard drives, Memory cards, Computer accessories, Graphic cards, CPU, Power supplies, Motherboards, Cooling devices, TV cards & Computing Components 15 Days Returnable The K702 also has a tad more extension than the 701, but it’s very, very close. Again, DON’T OVERTHINK IT! Soundstage: The K612 has improvements to the bass, but there will be inevitable trade offs made. One of these to a minor aspect is the soundstage. The K612s just cannot compete with the soundstage on the K701, K702 and Q701. They do however have a more open soundstage than the K240s. Despite not having as wide as soundstage as the leaner K7s, I do find the K612 soundstage more natural due to not having the tendency to pan extremely left and right with mono recordings, causing the center stage to go dead like the K701/K702/Q701s do.

A falta de pruebas más concluyentes, me pensaré si invertir en modelos superiores, o cambiaré de marca/modelo. Me había ilusionado por este modelo por sus buenas críticas ya que mi presupuesto es reducido, pero como digo, la calidad de sus materiales me ha defraudado; no así su sonido que ha mejorado sustancialmente con respecto a mis anteriores audífonos. ¿Merece la pena su compra?, si se tienen en cuenta los inconvenientes señalados, o si su presupuesto está muy recortado,SÏ; si se puede "estirar" el presupuensto, hay otra marcas/modelos que dan la misma (o mejor) calidad de audio y de construccion; pero hablamos de mas del doble de precio....

Boring sound - depends on your definition, but if you're looking for great sound clarity and detail, great sound positioning and a wide soundstage that makes songs sound like you're in a concert hall, you're sorted. It doesn’t always manifest, but can be problematic at times. A minor flaw in an otherwise amazing headphone. The K612, K712, and K702 represent the most significant discrepancies between the entire line of K600 and 700 headphones.

K612 PRO | Reference studio headphones - AKG

is not a basshead can by any means, but this is one of my top recommendations for EDM and many modern bass heavy genres, because this can render deepest low notes with exceptional texture. If you are used to heavy boomy, untextured bass presentations, 612pro will surely show you what you have been missing all these years, finally you can reinvent yourself as a real basshead who admires deep textured bass presentations. 612pro is surely is a fantastic option for vocals too. Vocals sounds very natural due to excellent neutrality of the mids, instrument timbre is very lifelike, very transparent, vocals can be upfront and can be very intimate sometimes. To me, this is a true all-rounder which can perform well in almost all the genres. My source in testing is the 1/4inch headphone output of my TEAC UD-H01 DAC/Amp connected via USB to my Windows 8.1 desktop. I use the foobar2000 player with EQ off playing various files from FLAC to m4a to mp3 (VBR/CBR 320). In terms of sound signature preferences I like more mid centric headphones with tight, accurate bass (quality over quantity). I frequently have long listening sessions and I do get irritated by sibilance on certain bright headphones like the DT 990. I enjoy all genres of music spanning across many different era's. Enough about me, I've had this headphone for a few weeks now and after 50+ hours of burn in and constant use I am happy to share my experience. K702 are flat with slightly more bass roll-off (low bass), and a bigger peak in the upper mids/treble. K612 have slightly more bass (marginal), remain quite flat, and don’t have quite the same peak in the highs (a little ‘more polite’).There is a small (1.5dB) level matching difference between Left and Right driver between 20Hz and 1kHz but did not really detect it at all. It is there non-the-less and seems to be a driver variation difference. I re-measured it a few times, just to make sure.

Both my NFB-12 and the LD MKIV (to my ears) are very good with the K702 and K612. I definitely don’t feel I’m missing anything. My actual preference with both is the NFB-12 over the LD. About your specific headphones you mention. I have two units of K702, and currently they're my joint favourite headphone with my Sennheiser HD560s. K702 has a really quite unique soundstage that is wide & expansive with some very impressive overall detail/resolution (all my experiences I'm talking about are when EQ'd to the Harman Curve). My HD560s has a narrower soundstage, but it's very accurate positionally within that less expansive soundstage.......the bass is also very very good in the HD560s. So they're my two favourite headphones out of the various headphones you see listed in my sig........you can see there's still differences between headphones when EQ'd to the same Target Curve. Wow. These cans have absolutely blown me away. The treble has settled down completely and now sits perfectly with the bass and mids. The entire spectrum is wonderfully blended without sounding messy or lost, and the imaging seems to have improved as well; the sense of space is more natural and the separation remains consistent without isolating instruments completely from one another.

What’s obvious is the resemblance above 5kHz to the K400/500 above. The K612 has a similar ‘bump’ around 2.5kHz followed by a small dip. The K612 doesn’t show the typical roll-off below 100Hz which the 400/500 series shows. In fact I would say it is rather flat.
