The whole idea of "scaling" gets blown out of proportion around these parts. The 600 sounds great plugged into my TV's headphone jack. Yes, the sonic improvements are significant with additional amplification, but people make it sound like you absolutely can't use a particular amp with the 600...

Also, the HD600 has a small peak in the 3-4 kHz range where the human ear is most sensitive. Even a couple dB of boost here will stick out like a sore thumb. The X2, in comparison, is under-emphasized in this range, which makes it more forgiving of harsh recordings.

Maybe...it could also be that you're getting a proper seal. I tried out the original K550 a while back and bass-tested it using Young Jeezy - Put On. The song starts with a 27 Hz tone, which rumbled forcefully through the K550. I have a slightly larger than average head and had no trouble...

I have the K545 and I haven't found a suitable replacement either. The problem is the circular pads. I tried the HM5 oval pads with the K545 but they screwed with the frequency response too much. Fit was imperfect as well. On the other hand, a headphone with oval-shaped pads like the M50 or Sony...

Don't know about your IEMs, but I have a 3-year-old M50 that I still use as my outdoors headphone and with the EQ dialed in, it's a worthy complement to the HD600. I'm still waiting for a closed headphone without any peaks and dips in the treble. I wonder if that's even possible in a closed design.

The 770 is thinner overall than the M50 and especially the M50x because of the infamous "Beyer peak". While a lot of headphones have a treble spike near 8-9khz, the DT770, like most other Beyerdynamic headphones, takes this peak to a new height, literally. This can lead to an initial impression...

For a while the DT770-80 was my main headphone and I still listen to the M50 (old version) from time to time, and the M50 definitely has more bass impact. The bass response is very snappy and punchy. The 770 always sounded bloated to me; too much midbass. The M50 has a midbass hump but it's...

I'm familiar with the basic concepts of crossfeed, personally I leave it on all the time as it doesn't mess with the FR too much with the moderate settings I use (650 hz lowpass, -6 to -7 db crossfeed level depending on the headphones I use). These settings are for Neutron and foobar2000, which...

Does anyone have any idea how the crossfeed circuit changes the frequency response? I like having the option to use with Spotify or any other time I'm not using Neutron Music Player with its built-in crossfeed, but the E12's crossfeed seriously kills the high frequencies. I was thinking about...

The HD600 is not that hard to drive. It sounds great out of an iPad, it's just not very loud. It can be driven "properly" by just about any headphone amplifier, including high-impedance tube amps. It doesn't have weird amping requirements like certain low-impedance, low-sensitivity headphones...

I don't know what you mean by open back HPs giving a better example of the low end, most open HPs are rolled off in the bass, with the Audezes being a notable exception. Ideally, you want as flat a response as possible for mixing. I consider Sennheiser HD 600s to be good mixing headphones...

Hey everyone,   I managed to tweak the E12 bass boost curve using a little subtractive EQ. I used the Golden Ears Accudio app on my iPod as it utilizes a useful frequency graph that illustrates what you're cutting/boosting. I also used the E12 bass boost frequency graph on fiio.net as a...

I tried out the X2 late last year before settling on the 600. There was something off about the X2's treble. I appreciated the robust bass (for an open headphone) but the low bass was still rolled off and it doesn't really extend that much lower than the HD600, maybe a third-octave lower before...

Using Neutron Music Player: Center frequency: 255 Hz Gain: 3 dB Bandwidth: .805 octave Center frequency: 8500 Hz Gain: -4 dB Bandwidth: .36 octave High shelf cutoff frequency: 14000 Hz Gain: 3 dB Q: 1.0

  To me, that's pretty crazy. I was just on the subway with my AKG K545 and FiiO E12 and I needed to activate the bass boost to minimize the subway rumble. Using open headphones on the subway is a sure way to murder your ears. Of course, I've seen/heard a million people on subways and trains...

  If the E17/E09k combo is powerful enough for you, keep it. The Magni outputs slightly more power (260mW into 300 ohms vs. ~150 for the E09K). Distortion on both combos is low enough to be inaudible. The E09k has a 10 ohm output impedance, which is not a problem with the HD600, but if you're...

I just got the E12. Holy schiit, this thing is powerful. And it doesn't sound treble-tilted at all. The HD600 hooked up to the E12 sounds just like it does with the E07K/E09K. The crossfeed sucks out a lot of the energy from the music and is basically a high shelf filter, but I've learned to...

I replaced my M50 with the DT 770 3 years ago. Went through 2 pairs before giving up and going back to the M50. My 2 DT 770s had bass rattling in the left earcup, eventual loss of bass in the left channel, and massive bass distortion at high volumes. Usually when a headphone has been around for...

I agree that JRiver has a poor crossfeed implementation. I've tried a bunch of different crossfeeds and keep going back to bs2b. It does muddy the sound to some extent but using a low shelf EQ compensates for the change in frequency response. There will always be give and take with crossfeed...

What about frequency response though? I've seen a couple measurements showing the E12 with a 1 dB variation between 20 and 20 kHz. Is that enough to be audible? I was considering the E12 but ended up getting the E11K as I will mostly be using it outdoors with my AKG K545. The E12 would be nice...

I just got a E11K and plugged the HD600 in for kicks. I was surpised that I only had to turn it up between 3 and 4 out of 9 on the volume knob, on high gain. My average listening level is in the low 70s.

Some headphones are easier to EQ than others. My old DT770 Pro was a pain in the ass to EQ because it had a series of peaks and dips in the treble. My HD 600, on the other hand, doesn't have any major treble peaks or dips. The only corrections I have made are a low shelf EQ, +4 dB with a 65 Hz...

Went through 2 pairs of DT770s with a bass-induced rattle in the left earcup. Sent the 2nd pair to the Beyer repair center and they did nothing to fix it. I know I'm not the only person on Head-Fi or anywhere else who has had this issue. The build quality of Beyerdynamic headphones leaves a lot...

OK, that makes sense. To my ears, the treble has a slight metallic quality, but that's because the lower treble and uppermost treble (>14 kHz) are recessed. With a little EQ applied in these two regions, the treble sounds wonderfully balanced. Conversely, if I wanted a darker sound, I would just...

I had forgotten where I read about the HD 600's driver resonance pre and post-break-in. It was in an article posted by...that guy who should not be named on Head-Fi. ;) His observations were with the HD 650 and while a resonance shift does occur, the difference is, in his words, "so slight it's...
