post #1561 of 2232

Thanks for the EQ suggestions, I've read that the 2khz bump is quite noticeable. Are there any equalizers for windows that I could simply put as a backround process and would work like a, let's stay ReaEQ vst -plugin? (So I can surgically find the correct eq settings for me).

I decided to jump into using Equalizer APO, so I can get a Windows 7 OS system wide EQ. I am now using EQ APO with Peter's Peace GUI EQ Addon. First, run and install the APO EQ. Next, run "Configurator" file, and select the source you want to EQ, and reboot. After rebooting, you copy the Peter's Peace GUI file into the config folder for APO Equalizer in and run it from there. After you have selected your EQ adjustments you want, you click on the "Save" button to save your selection to the folder. You now just minimize Peter's Peace GUI. Boom, you now have an easy to use GUI for APO. You can add bands, remove bands, and change the band values quite easily. It turns out, after some critical listening, that the midbass bump is not needed with the K612 Pro. Once again, I have made some adjustments to the EQ, and I am now using the following across Windows with APO EQ with Peter's add on. Be aware that with Peter's EQ GUI add on you can change the actual band numbers on the fly as well. Such as, changing 2.5 Khz to 2 Khz, and saving it as such.

 

42 Hz @ +1
55 Hz @ +1
77 Hz @ +1
2 Khz @ -3

 

This offers me the best sound I have heard thus far on the K612 Pro. I love that this is activated in the gaming environment as well. Feel free to give it a try. Let me know how you like it. You can get the APO EQ, and also Peter's EQ GUI add on at the links below. 

 

Edit: One more thing to note is if you are using the EQ which comes with foobar2000, you should disable it. Otherwise, you will be using 2 EQs.

Ounamahl, in the settings for Peter's Peace GUI, you can set it to run in system tray, and to start on system start up. You can also adjust EQ settings and save them on the fly. It does not get any easier than that.

Quick question for DW75 or anyone else for than matter.Been listening to the K612 out of my Little Dot MKIII. While listening to certain music I hear a slight distortion in the mid range. It is only with certain songs and does not seem to be there with other headphones. Could this be a byproduct of the 2K bump I've read about with these headphones? Could the distortion be in the recording but is only being reveled by the K612? I have an Audio Control EQ but am not using it at this time. I listen to physical Cd's through an Oppo player. Any thoughts?

Does it happen on lots of tracks or a single track?

K612 is very unforgiving. My friend made some CDs from his vinyl collections by using Rockport turntable. the details, air and sibilance are amazing. However it will be good f you can apply foobar2k's EQ to verify the possible mid distortion.

I heard it for the first time last night on a specific disc, I tried another disc and the distortion wasn't present. I then threw on another pair of headphones and didn't hear it. I need to listen more and try to determine if it is in the recording and being flushed out by the spike of the K612's or if there is another problem. BTW my K612's were received new sealed and look to be put together very well. No physical construction issue's and they sound great (except for the distortion).

Unfortunately I can't use foobar as I don't listen from my computer. I listen to actual physical cd's. Old skool and proud of it! :L3000:

That's the grain that is present in the upper midrange and is one reason it lacks a bit of refinement compared to the K7xx(which are more forward in the 2khz region yet smoother). I think it may be more of a driver limitation as I hear it slightly even when I eq the headphone. That's honestly the headphones only real flaw to my ears.

old school too, still prefer 200+ lbs speaker,  just started to try headphone. Never too late for an old dog to learn new trick.:o2smile:

It is fun to play around the digital processing built in the foobar2k, but not EQ.

post #1570 of 2232

OK, so the distortion I am hearing is an over saturation in the actual recording itself. It is present when I switch to my DT880's but I still learned something about this headphone, it really emphasized the problem in the recording where the Beyer's were sooo much more forgiving IMO. And of course now I hear this emphasis in those frequencies on most everything I play on the K612. On some, really most recordings it's not that bad but on way too many I am hearing things I haven't heard before in a bad way.:(

post #1571 of 2232

Please try "time" from PF's "the dark side of the moon" if you are a rock fan, the saturation, or so called clipping, is much more evident on K612 than on the others. Generally speaking, the clipping is a recording flaw due to poor gain control, not tied to a specific band.

I hope your wrong and if I break out my Audio Control EQ I can correct this. What blows my mind is my $40. Superlux HD668b do not have a hint of this issue and sound fantastic to me but they did need awhile to burn in and tame some really shrill highs. Maybe a little more burn in for the K612 is needed? I'm probably around 30-40 hrs of burn in at this point.

Listening to it now but truth is I'm not really a huge PF fan so not sure if this sounds worse than it would to you... it doesn't sound that bad to me.

 

Is it a real obvious nasty clipping distortion? If so I'm not getting it. The beginning had some nasty saturated distortion but now it's settled down and sounds pretty good to me. I am hearing some clipping in the recording of the cymbals and drums in general. Listening as I type here. Didn't sound as bad as some of my own songs I listen to much more frequently.

BTW that was an awesome tune.

  1. k612 does take time to break in, some say break-in is a myth, not for k612.
  2. through unforgiving HPs, good recording sounds great but poor recording sounds horrible, good or bad? personal preference. I definitely like to own one
  3. about the treble, it might sound harsh or grain sometimes, honestly speaking it is what the live music is about. The sounds of most instruments do not sound that smooth or refined.

There is no question that these headphones require burn in. I found the most noticeable changes happened during the first 8-12 hours of use. The treble smoothed out, and the mid bass tightened right up during those hours. These headphones have a great sound signature. It is fairly neutral, and rather musical sounding. That being said, they do have a rather prevalent spike in the 2K-3K region. I use the following EQ set on my pair.

 

42 Hz @ +1
55 Hz @ +1
77 Hz @ +1
2 Khz @ -3

 

For me, this offers a great sound. It gives a slight bump to that sub bass region, and cuts that 2K spike right down. These headphones certainly offer a great amount of detail retrieval for the 200 dollar price level. This will result in them not being the most forgiving on poorly produced music though. I have noticed some grain and distortion on a few badly mixed albums as well. You can be assured though that the headphones are not defective in any way. They are just showing you how much crap is in the mix. Interestingly enough, that additional sub bass I am using on the EQ also results in some grain being removed in that 2K-3K region. Honestly, that EQ set I am using greatly improves the sound of this already great pair of headphones. Give it a try, I think you will like it.
