Hello everyone, I'm going to go ahead and try my hand at posting these impressions on the HE-1K, which will be my first. I eventually want to do full fledged pro-style bad-ass reviews, and I so I have to start somewhere. Since I've never really shared headphone impressions, my tendency will be to, in some spots, compare them to my current phones, the LCD-X, and the previously borrowed HD-800. I'd like to point out that:
-I like most types of music, but the majority of my interest centers around rock, alternative and metal.
-I listened to all types of music to get a good feel for the headphones, to form a more fair assessment.
-I rented these headphones, brand new from thecableco.com.
-I was told that they were burned in for "a couple days" before being sent.
-And of course, this is all just my opinion. I'm not the narcissistic jackass to presume to state any of my opinions as fact.
My initial thoughts that came to mind when I put on the HE-1K were about the overall clarity of the sound. Microdetails were presented in a very crisp, revealing manner. It is probably the clearest, cleanest, most detailed headphone to which I've listened. The reason this is really significant to me, is because these headphones don't sacrifice realism for clarity. What I mean by that, is that I feel sometimes that the higher a headphone's resolution is, the more artificial, dry, and "digital" it sounds. I don't want to feel like I'm listening to a recording of music sourced from electronic components, no matter how good, or "true to source." I want to feel like I'm in the audience of a live performance, or in a studio with the musicians. On the other end of the spectrum, I feel that some headphones that maybe aren't as crystal clear in presentation, end of giving the impression of a more natural, organic, and live sound, like perhaps comparing a cd sound to an lp sound, or a tube amp to a ss amp. If I had to choose between the two sonorities, I would choose the more natural sound, because I'm a musician and am around live music all the time. Luckily, this headphone does not make me have to choose. I get both a natural and crystal clear aural picture, which is no small feat for any headphone.
The soundstage resembles that of the HD-800, which is to say, more spacious, airy, wider than that of an average headphone, with more width than height. I didn't feel so much like I was listening to a pair of headphones, but more to a set of ear-speakers.
I find the imaging on the HE-1K to be spot on. I could close my eyes and know exactly in the recording where all of the instruments and voices were located. This gave the overall presentation a slight 3-D effect, or a binaural recording, like the music was surrounding you, as opposed to a presentation on a 2-D plane that takes place directly in front of you.
The quality of the treble is airy, crystal clear, sparkles when called for, and compared to the mids, seems much more present. If turned up to loud listening volumes, the treble can at times seem to be a bit overbalanced.
The mids are something that I feel to be the one glaring weakness (besides the price) of an otherwise amazing set of cans. Considering the stunning clarity that the HE-1K offer, I still knew immediately that something left me wanting, and was just missing from the picture. I honestly feel like someone took a vacuum and sucked the presence of the mids and upper bass out of this headphone. Listening to rock and metal, I'm left wanting for guitar, and the general "meat" of the overall sound. Features like guitar solos and driving rhythm lines in many cases are just not balanced well with everything else. That is huge deal for me, because the biggest strengths of the LCD-3 and maybe less so the LCD-X, (my current favorite headphones,) are the big, beefy mids. The mids bridge the gap between the melody (treble) and the foundation (bass)! That means that there's something in 33.3% of the complete aural spectrum that's obviously missing. And while it was difficult to completely pinpoint initially, it is the reason that I find these headphones to sound really pretty, but in some cases, too polite. I like a lot of visceral slam in the bass, it makes the music more engaging, and lifelike. This headphone lacks that sense of engagement, and can at times come across as boring.
There are two parts about the bass, and the first coincides with what I said about the mids. The upper bass/lower mids, as mentioned above, seem to take away from the slam and emotive effect that true-to-life music should produce ....
The sub-bass, however, is AMAZING. It's my favorite feature about these headphones. Never before in a headphone experience have I felt such presence, depth, extension, tone and clarity in the sub bass-presentation. It's a huge plus for those who enjoy EDM, Hip-Hop, or other bass and percussion heavy genres. It's also what makes the experience feel more speaker-like.
In conclusion, I find the HE-1K to be one of the most beautiful sounding headphones in production. It is crystal clear, natural and organic sounding, has great soundstage and imaging, sweet treble, and amazing sub-bass. However, the mids and upper bass are weak, especially with rock/metal, or energetic music. This is a deal breaker for me since I listen to a lot of high octane audio, and these headphones do not engage me the way my LCD-X always do. Plus, the retail price for these suckers is $2,999, which is not a great value among other flagship phones (minus the Abyss and the 009, the only other high-end phones on my list I've yet to audition.) In addition, the improvements of the listed strengths of these cans compared to other top flagships are noticeable but not monumental. The obvious aforementioned advantages that the HE-1K have, just aren't enough. I understand the law of diminishing returns, but even then I still prefer my LCD-X, and I feel like a more fair price for the HE-1K would start at least at half their MSRP.
Some random notes:
-Piano is very natural sounding. Least digital sounding piano I've heard from headphones, very lifelike. Same with acoustic strings.
-Same with vocals, which sound smooth and real, as if the singer was serenading you.
-This headphone excels with acoustic music, like classical/jazz and seems it was voiced and tuned for those genres. (not unlike the HD-800)
-I like listening to headphones a bit higher past normal listening volumes. I can't do that with the HE-1K. Like the HE-6, I can't usually get to the desired listening level I want without hearing a bit of distortion. As soon as I hear even a hint of distortion, I have to dial back on the volume so I don't damage the drivers. I'm not sure if this is just a phone/amp matching issue, because my M9 packs plenty of power.
