Not sure if it can maintain voltage delivery and still have well over 200mW for the HD650 but I would assume it won't be a problem. NuForce claims 500mW from that, likely at 32ohms, so it likely has enough power for it. K712 is harder to drive so if you're just about to buy an amp, the savings will just more likely end up spent on the amp.
K7xx series has self-adjusting headbands but if your head is too large it can't flex more to loosen the clamp (which might make the treble stronger), or if you have a smaller head, it can't get any tighter (likely getting you weaker bass).
HD6xx needs manual adjustment to get right (in terms of comfort and/or sound). They're about even on those but since the AKGs are round, if you have sensitive skin, there's going to more earpads towards the center of your face, so if you react to these they could be at a more visible spot. Won't give you anywhere near K70x imaging in terms of size but it makes the HD6xx series' soundstage even more proportional as the cymbals are moved backwards. K712 has flat pads so they're not as demanding of using the older angled pads for you to preserve the imaging (that said, using the older pads might improve it), but they cost more and can be harder to find other than direct from AKG and a few sites.Īmazon has Sennheiser pads and if you gut them the Brainwavz HM5 pads can give you some options.
Subjectively, people will claim they can't hear the treble. From an objective standpoint the relatively smoother curve of the HD650 arguably has less drastic deviations from 1000hz. I just really wish I could try these out but in the end, I think I'll be happy with the sound of either.
I realize that you can get spare parts for the 712 Pro as well, but they are quite pricy - a single original earpad costs 50€ (roughly $58) whereas a pair of original HD650 pads is 40€ (roughly $46. I also like that there are many spare parts available for the HD650 (earpads, headbands and headband cushions.). I realize this is fairly relative, but still, I feel the HD650 is a safer bet. I've read about problems with the 712 Pro such as the headband losing tension over time, tendency for the headphones to slide down especially on smaller heads, the headband not being comfortable. That said though, I think I'm still going to go with the HD650. There is also a sound demo for the 712 Pro but unfortunately the songs are different, so a direct comparison is a more difficult.
Above I mentioned sound demos for the HD600 and HD650.
The headphones would be driven using my NuForce UDH-100 amp/dac combo.Īny insight on the two headphones would be greatly appreciatedĪwesome, thank you for the detailed comparison.
over-ear design (I don't have a preference for open or closed) decent build quality with spare parts (especially pads) availability neutral sound - I mainly listen to rock and metal, with the occasional electronic music thrown in the mix To provide some more information, here are some things I wish for in my next headphones: I can get the HD650 for 325€ (roughly $380) and the K712 Pro for 225€ (roughly $260), both brand new.Īssuming the HD650 are better (relative, I know), are they worth the extra $120 over the K712 Pro? Unfortunately, I am unable to try either of these out, so I'm hoping I'll get some help here, though I realize these things are somewhat subjective. The dilemma I've found myself in has to do with the price of the headphones. There seems to be quite a few comparisons between the two and form what I have gathered, people generally seem to prefer the HD650, both in terms of sound as well as build quality. I've been eyeing the Sennheiser HD650 for quite some time now and was pretty much set on them until I came across the AKG K712 Pro. I'm in the market for some new headphones and have reached a bit of a dilemma.
