That being said I could drive it from moderate to ear bleeding levels from 11 to 12'oclock on the volume knob. A mini-XLR connector is included, ensuring replacing your cable is fast and efficient, while an additional coiled cable and a premium carrying bag have also been added to the mix.

AKG K-612 Pro – Thomann UK

I’ve personally never found the AKG x701/2 series to sound ‘plasticy’ in the mids (as others have found them) – of course this may well be my amp (NFB-12 is quite full bodied – powerful, but maybe slightly coloured). Para escuchas con el volumen alto hay que echar mano de la ayuda de un ecualizador porque como todos los cascos, los agudos crecen, empiezan a salirse de madre y los graves, que apenas crecen, se enmascaran por los excesos de brillos. Some of the ‘harshness’ in the treble is lowered and you don’t get the sense of ‘hyper detail’ any more. Desire to learn and share knowledge of science required as is 20 years of participation in forums (not all true). I’m fairly certain now that I’m going to end up with either 2 or 3 cans – RS1 + either HD600 and/or HD800 and/or Alpha Dogs (trialling soon).It sounds very particular, and though it presents everything flat and in good detail, nothing I hear sounds very good or appealing to me.

Please give us the reason for your assessment in the following text box and – if possible – your e-mail address for further questions. Cable is strong and thick, non detachable cable isn’t/wasn't a big deal breaker for me, still compared to 7xx series, 612 uses lesser quality materials (plastic, leather headband) and can gradually loose the elasticity of the auto adjusting headband mechanism over time. Took about a week to break the headband and pads in, though for me nothing about the way these headphones sat was noticeably irritating.They are replaceable and have a very easy way of detaching and reattaching – just rotate and pull gently to remove, or sit them almost over the latches, push and rotate to reattach. My TEAC is not considered very powerful (40mw RMS at 32Ohm) so I would say anyone with a modern desktop or even portable amp should be fine.

AKG K612 Pro Studio Headphone Review - Sonarworks Blog

But be warned, this is not an easy headphone you can drive without an amp, you must use a decent amp/dac to get he most out of this, I found 612pro is harder to drive than DT150, dt770. When you first wear the headphone on your head, after 5 minutes, force on your ears might be a problem especially if you have glasses. it's the best out of them when all are used without EQ, just the soundstage is the worst and the bass is not the best, so those two reasons are why it's my least favourite headphone out of the ones I own.Despite the not-so-high impedance of 120Ω, with K612 Pro you’ll achieve lower volume levels from mobile devices than you might expect. The headphone is very light and the clamping force of the earpieces is fairly gentle, the leather headband sits gently on the head too, and the cushions which are soft and pliant don't cause (me) any irritation.
