Equalizing those headphones!

Q: Is it a good idea to use an equalizer to change the way headphones sound?

A: While you can make some tweaks to a headphone's sound profile with EQ, some fundamental characteristics are impossible to alter.

For example, no amount of EQ can make a Grado SR60e sound like a bass monster, similarly no amount of EQ can make a Sony XB500 sound like a Grado.

Neutral headphones are somewhat like tofu -- they can take on a little of the flavor of the amp that drives them, or the DAC that feeds their signal, or EQ in the audio chain, either by using software or hardware. They still taste like tofu, mind you, but flavored.

While you can buy a relatively neutral pair of headphones like the Sennheiser HD600 and tweak the sound with an equalizer, I'm one of those folks who think that if you want a warm fun sound, it's better to get a Philips Fidelio X1 instead of using EQ to tweak a HD600 to make it sound warmer.

And if you want a bright-sounding pair of headphones, check out the Grado SR60e before throwing down money on a HD600 and trying to boost the treble with an equalizer (and you will save a ton of $!)

And while you can use EQ to dial in some of the frequency response you want, you cannot use EQ to dial in your desired level of smoothness, or soundstage, or detail. Plus the more you flog that equalizer, the more the sound gets away from what the artist and recording engineers originally envisaged. That's the main reason why I am so meh to the idea of equalizers.

But to be fair, it's easy to say "I am anti-EQ" if you own a bunch of headphones and can easily pick and choose a pair with the profile you want. But what if you can only afford (or desire) one pair of headphones?

Well in that case, if you are sure you know what kind of sound profile you dig, then the choice is easy (e.g. you want a smooth + forgiving? Then go with the Sennheiser HD650!). But what if you don't know what you want?

Then walk into a B&M store and audition some headphones. But what if you can't?

Then get a relatively neutral pair of headphones like the HD600 or the Beyerdynamic DT880 and experiment with EQ.

Because they are like, you know, tofu.

What is a "sound signature"?

Q: What do you mean when you say "headphones have specific sound signatures"?

A: Different headphones have different signatures. For example the Beyer DT880 or Senn HD600 are more "neutral" sound profile, i.e. they are free from coloration,

Coloration refers to deviations from neutrality, for example the Philips Fidelio X1 is very colored. Coloration also often adds a "fun" element to listening.

Some headphones are intrinsically dark -- the term signifies a warm + rich sound profile. Technically, dark headphones have a frequency response which is skewed clockwise across the entire range, so that as the frequency increases, the output diminishes. A good example of this would be the HD650.

Other headphones are very bright, their frequency response is skewed counter-clockwise across the entire range, so that as the frequency increases, the output increases. A good example of this would be the Grado SR60i or e (or pretty much any Grado).

What sound experience do real audiophiles want?

Q: Do real audiophiles progressively move toward the most neutral experience they can get?

A: Not all audiophiles, it may be better to use the word "some" instead of "real". Rather than call it "neutral" vs "colored" or "objective" vs "subjective" I think of the listening experience more as being "analytical" vs "fun". I'll explain what I mean.

Some times I want to get the source recording, the whole source recording, and nothing but the source recording. While you may think this desire only extends to classical and/or live performances, in reality there are times when I ant to hear music the way the artists/ producers conceptualized it. So for example when Daft Punk won the "best engineered album" award at the Grammys, I wanted to go back and hear RAM exactly as it was on my source file, ni plus ni moins. And the best way to achieve it is with a neutral DAC, a solid state amp that does not sound too bright or too dark, and something like the HD600.

But at other times I want a completely different experience. I want the violins in Mendelssohn's Concerto in E minor Op 64 to come out of the orchestra and smack me across the face, I want Christina Novelli to breathe in my ear when I hear Garth Emery's "Concrete Angel", and I want that in-your-face Southern rock stance when I listen to 38 Special's "Caught Up In You" and perform right alongside them on stage with my air guitar. And frankly, for any of those scenarios (classical, EDM, rock) when you want a more "fun" experience, the analytic set up fails. So an alternative set up with a warmish DAC, a tube amp and a HD650 or Fidelio X1 will give you a very different (and probably more pleasing) experience than the one I outlined in the previous paragraph.

So what headphones like Grados offer is a "fun" experience. And while "fun" is good, there is a totally different "analytical" experience out there waiting to be discovered. Some may enjoy it, some may not. And for everyone who enjoys an "analytical" experience, there is a "fun" experience waiting around the corner to surprise and thrill them. That's why there are so many headphones out there.

I just realized that everything that I said about headphones also applies to your spouse/girlfriend/boyfriend/significant other. Sometimes you want fun, and sometimes you want analytical.

Well we're movin' on up to the east side. To a deluxe apartment in the sky.

Q: I have a Sennheiser HD600. What do I upgrade to?

A: Until some years ago, the HD600 was the flagship model from Sennheiser. They are a great neutral headphones, and are good for a huge range of music. The problem is, when you have something as versatile as the HD600, do you really need to upgrade your headphones?

Obviously, no. I could argue that if you want a neutral setup, you could be perfectly satisfied for ever with the HD600. But if you have the disposable income and want to expand your headphones collection, I would argue that you need to consider one of 3 options:

1) Save up for a higher tier of headphones - consider the Audeze LCD3 or the HD 800. Both have different profiles, and both offer significant advantages over the HD 600 that makes their high price possibly worth it. But this would make the least sense from a price-performance perspective.

2) Get a headphone that has a very different profile than the HD600 -- something that gives you bass-rich oomph like the Beyerdynamic DT990 or the Philips Fidelio X1, or something that is treble-forward like a Grado. Each has a characteristic sound profile that will offer a very different listening experience for certain types of music that accentuates their tonal features (e.g. try 2pac on DT990 or Steely Dan on a Grado)

3) Get an IEM to complement your HD600s. That's like opening a whole new Pandora's Box.
