I received a PM to compare 3 headphones.
I thought, I share the question and the answer here, as it might benefit others.
"-Hello can you tell me how the X2 pair against the 400s, nighthawk?
- Hi,
All I can tell you is my personal experience.
Some headphones are better with certain music, others are better with other type of music.
HD600 for example is great with classical and acoustic music, X2 is a good opened headphone for electric or contemporary music.
Also the picture is changing depending on the DAC or headphone amp you use.
Some headphone/DAC synergies are better than others. (I use Chord Mojo.)
And all of this comes down to personal preference.
Some people prefer neutral, natural sound, some prefer a bit more bass and fun.
I am looking for fun but quality sound. I prefer a slight bass emphasis over neutral, so bearing all of this in mind here is my very brief comparison of X2, 400s and Nighthawk (using Mojo):
X2 and 400s are opened, NH is semi-opened.
Therefore X2 and 400s have bigger soundstage, much more air, space to the sound.
NH is much more forward. Music is closer. More intimate.
I favour 400s the least due to my preference.
400s has a very clean sound with black background. Very natural, especially in mids. The best of the three for natural voice/vocal. And classical. Bass is far more the weakest of all three. Natural listening experience, but not fun at all.
X2 is my personal choice for now (waiting for TH-X00) mainly because of the price for value.
X2 is opened, so you have the space and naturalness.
Also, with X2 you have a pretty decent bass. Not as deep and punchy as it can be with a closed headphone, but maybe the best you can get with an opened dynamic headphone.
Not as neutral as HD600, but much, much more fun. Does so many things on such a good level, that makes it unbeatable for the price. Even for twice the price it would be unbeatable.
NH is another awesome headphone, but even second hand it costs more than twice as X2.
Bass is awesome. The best ever. (Haven't heard X00 yet.) Very dark, very smooth sound signature.
Bass is just extremely enjoyable. Better than X2 bass.
Mids and highs however feel a bit closed and congested compared to X2. Also less natural, less airy.
400s was not a contender for me knowing my preference of music and sound signature.
I could live with both the NH or the X2.
However I prefer the opened airiness of the X2 over the better bass of NH. Even though I am a bass enthusiast.
Not to mention the huge price difference.
I am hoping X00 will have the same good bass of NH, (if not tighter and more precise).
And a bit more spacious and opened mids and highs..
Will see.
400s is a no go for me.
I would probably choose NH over X2 if they were the same price. (£165).
NH being significantly more expensive, my vote is X2 for now.
I am waiting for X00 to convince me it is worth the extra cost.
Hope my insights help you."
