Summary: First impressions
When I first tried these headphones out of the box, I was a little disappointed at how the higher frequencies seemed to be more forward than the mids and bass. It wouldn't have been a huge deal, except that the treble was also completely unforgiving on sibilant tracks, which really put me off. The saving grace at the time was that the bass, while not having a huge presence, had a buttery smooth texture that made my mouth water.
Pros: Bass texture, incredibly smooth across all frequencies
Cons: Treble can be harsh at first; takes time to mellow out
Summary: this is my first "serious" pair of headphones So the review cant be very full, but I try to give the possible useful information. I was looking for a pair of headphones with a neutral sound but with a good bass impact and suitable for gaming, and i am very satisfied with them. they do very well with all my music: particularly they are fantastic with black eyed peas and alicia keys ( quality of bass and voices is fantastic !) .
Pros: neutral but good impact in the bass, tights bass, price,great for gaming, design.
Summary: This is a brief review of the K612 Pro, to my ears it's my favorite and the best headphone under $200. I'm using a Hifiman EF2A as an amp and an ASUS Xonar DX as a DAC.
Build Quality: The K612 is a well-made headphone and feels solid in my hands. Only gripe is the cable isn't detachable but it's not really something I'm worried about as the cable quality is good and I take good care of my headphones.
Pros: Detailed, transparent, smooth and linear sound, revealing, very natural sound, precise imaging, good sounstage, non-fatiguing, and comfortable.
Cons: A bit finicky to amp, needs a good amount of power, and pads take a few weeks to break in.
Summary: Build Quality: Excellent.612pro is built like a tank. Really solid construction with nice professional looking open back headphone. Cable is strong and thick, non detachable cable isn’t a big deal breaker for me.
Comfort: I’d say pretty comfortable after few weeks. Velour pads can be little hard at first, but after few weeks it will become soft. 612pro doesn't have much clamping force, but for me I don’t like using them with my glasses on.
Pros: Excellent Imaging, Excellent refinement, Great build quality
Cons: 2khz spike, non-detachable cable, not cumfortable with glasses on (may be this is just me)
Summary: I have owned several other AKGs, including the K240s, the K702 65th Anniversaries, the and Q701 Quincy Jones Signatures (basically the same thing as an updated K701/702). The K612s sound-wise lie somewhere between the K240s and the K7-series, while having a unique sound signature of their own.
Build: Made in Austria, and very close to the K7-series, but not exactly. They feel high quality, but not quite as exquisite.
Pros: Roomy ear cups, smooth, linear, natural sound, non-fatiguing highs, well behaved bass, AKG mids, not hard to amplify
Cons: initial ear pad comfort, picky with DACs, hard wired cable (good quality though), not for bassheads, synergy with systems
Summary: AKG hat mit diesem Kopfhörer einen (weiteren) Sprung nach vorne gemacht. Ich habe ihn in verschiedenen Klangsituationen gegen meinen betagten 601 PRO sowie gegen den neuen 712 PRO getestet: - Elektronische Musik - Klassische Musik - Neue Musik - Drones - Verschiedene eigene Klangquellen (Analoge Synthesizer/Drumcomputer, digitale Synthesizer/Drumcomputer, Gitarre, Bass) Mein Fazit: Ein besseres Preis-/Leistungsverhältnis wird es kaum geben.
Summary: Mooie hoofdtelefoon, zeer comfortabel, en het geluid is gewoon perfect voor als je tracks aan het produceren bent. Ik raad hem niet zo aan om er muziek mee te luisteren met je Ipod of telefoon. Want het is ook niet voor niets een: STUDIOhoofdtelefoon.
