Bob (my cousin) even included a 2.5mm balanced cable into the mix which pairs very well with the FiiO K3 that I have here at the crib. He told me his plan was to invest in some sort of speaker setup and perhaps revisit headphones at a later date. For dance and electronic: They again can be bright at times; I guess that's a them. Others haven't mentioned it, so maybe I'm just not used to hearing this level of detail in the treble. It never hurts, but can get fatiguing to me. Bass is always adequate, as these tend to be modern recordings. Ace of Base's music is mixed perfectly. I'm listening to them now in High Quality through Apple Music and using the Dance EQ setting. It's perfect. One song that stood out to me was Madonna's Music. This sounds good flat on these headphones, but through my home speakers (Polk S55 powered from a 75 W/ch integrated amp) I have to turn the bass EQ all the way down for it to sound just OK. Extra Notes: In terms of EQ, these take EQ extremely well. The driver doesn’t distort at all from my experience, and you can literally put a bass shelf on these with absolutely no issues. These can turn into a v shape headphone if you want, so in terms of EQ, these are absolutely killer. These take treble boosts as well with no issues. Overall they are great in terms of EQ. For music production these are also quite good, as they are very balanced, although the darker treble response is a slight issue with music production. Midrange: Onto midrange, this is the highlight of these headphones. The midrange is very good on these, in almost every category. Mids and vocals have a fantastic amount of presence. Vocals never sound shouty or overly present, but they have this degree of separation from the rest of the music which allows for them to shine through in a way which is hard to explain with words. If you’ve never heard the midrange of a Sennheiser 6 series, it’s hard to explain. In a way, vocals sound completely clear in every song, but are never harsh or overly in your face. The S and T region of vocals are also never sibilant, as these headphones have a very natural sounding vocal presentation. The timbre is extremely natural and is the closest to a vocal in real life that I’ve heard. The midrange is very slightly more forward overall then the treble response and bass response though, so vocals will be more present then a flat response. In terms of warmth, these are more warm then other headphones, and that applies to most of the midrange, especially vocals. It’s an enjoyable warmth though, and isn’t muddy. For detail and separation in midrange, these do a very good job for the price, but not nearly as good as the 6XX. It is impressive though especially regarding how the treble response is on the darker side. Due to the treble response being darker though, acoustic music as well as orchestral isn’t fantastic on these, but it is passable I’d say. As a whole, the midrange is very impressive, especially for the price, and especially for vocals. Even though it isn’t perfect, it is very impressive, and among the best I’ve heard in a headphone.

The neat thing about the 58X is that its 150 Ohm Impedance is actually half that of the others in the line. Note: The measurements you are about to see are made using a standardized Gras 45C. Headphone measurements by definition are approximate and variable so don't be surprised if other measurements even if performed with the same fixtures as mine, differ in end results. Protocols vary such as headband pressure and averaging (which I don't do). As you will see, I confirm the approximate accuracy of the measurements using Equalization and listening tests. Ultimately headphone measurements are less exact than speakers mostly in bass and above a few kilohertz so keep that in mind as you read these tests. If you think you have an exact idea of a headphone performance, you are likely wrong! Still, the pattern manifests itself on quite a number of songs so I’m inclined to think the 58X is just a little overexcited at times, like your 8-year-old who just drank an entire 2-liter of Surge and won’t stop talking. Bass & Treble Fitment on the fixture was challenging even though the cups easily covered the artificial ear on my measurement fixture. This resulted in fairly large variations in bass response. I got the two channels to match which is a good sign but still, keep in mind the cautions above in bold. Also, due to this tight fit, the headphones won’t come of your heads like the HD 598SE does! So, you won’t have any type of fit issues like you had with the HD 598SE (where if you even sneezed, the headphones would’ve come flying off of your head!).

Please take my word on it, this last issue is so annoying that I'd buy an HD650 if the 6XX suffered from it as well. Just keep in mind that the headband has been known to snap under pressure like Henry Hill in Goodfellas.

Fortunately, everything else is mostly right, which is what has allowed me to keep these on my head almost indefinitely since I received them.

Comfort-wise, these are not the most comfortable headphones in the world to wear, but they are light enough to not be painful even when you wear glasses and use them for hours. The clamping force is a lot too strong when they are band new though, so it requires a few days for it to soften up.
