What does an Amplifier do for Headphones?


Why Amplify?

Even the most talented musician on earth or your all-time favorite number will not be able to make you relax (or make you dance, depending on what your intention was in the first place) if you can’t hear them properly. Your perfect headphones, which you bought only after intense research and personally trying on each brand and model, somehow are not living up to your expectations. You are unable to make them reproduce the same quality of sound that they did at the store or at the expo.

Unless your headphones are broken, the actual problem may lie with your computer or mp3 player/smartphone from which you are playing the music.


How does it work?

  • The music being played on your computer or your mobile device has to pass through a Digital to Analog Converter (DAC) and an Amplifier.
  • A DAC converts digital audio information into an analog audio signal.
  • This analog signal is then sent to the amplifier, which in turn sends it to the miniature speakers (drivers) of your headphones. And that is how you hear the music.

Now most music players, every smartphone/tablet, most computers already come with an inbuilt headphone amplifier. The problem is that these may not be good enough. Considering the size and space limitations of a mobile device, these in-built amplifiers have to compromise on power. The outcome is that your headphones will under-perform.

A stand-alone headphone amplifier can make your high-end headphones perform to their full potential as it (the amplifier) can supply much better power to your headphones. It also allows for better sound control.

The Top Things to Know About an Amplifier

Often times the function of an amplifier is confused with generating so much power that your headphones can reproduce the loudest sound. This is not what it is for. An amplifier is not supposed to make you deaf or annoy people around you. An amplifier should help your headphones reproduce crisp and clear but controlled sounds. It should eliminate the distortions even at the peaks.


Efficiency and Impedance

Now, to choose the perfect amp for your headphones, you should check the efficiency (sensitivity) and the impedance of your headphones. The efficiency indicates how loud your headphones can get when amplified. Headphones with 95dB or less efficiency will most likely need an amp. As for impedance, a general rule states that the impedance of your headphone should be 10 times the output impedance of the amp.

What to buy it?

You may buy an amp and a DAC separately, or you may choose a combo unit which houses both. The combo will work best with your computer. But if you intend to use your headphones only on your mobile device, you don’t need a DAC or a DAC – Amp combo. Only an amp should be enough.

Types of Amplifiers

A lot of different brands and models are available to choose from in the market. Each of Types of Amplifiersthese will have different form factors, different features, and different ports. Some of the general types are listed below.

  • Desktop Amps: A desktop amplifier will do the trick for you if your setup does not require a DAC. Alternatively, you may decide to buy the amp and the DAC separately and pair them up yourself.
  • Portable Amps: A portable amp usually does not come with a built-in DAC. But as discussed above, it may not even be required. A portable amp will work just fine with high-impedance headphones used with a portable music player/smartphone. Some of these amps are also battery-powered for increased portability.
  • DAC – Amplifier combos: These work well with headphones as well as speakers.
    Some headphone amps come with built-in DAC’s. They connect to the laptop / desktop / tablet via a USB or optical port.


Final Word

Whether you buy an amp or a combo will depend on which devices you intend to use them with. A decent research should narrow down your choices. But remember this, an amplifier should give you cleaner, better sound that you can enjoy. It should not blast your eardrums away. Enjoy your music responsibly, in a healthy manner and be considerate towards people around you.

Now, go boogie…or relax, whatever!

Discover Just How Black Women are Taking Care of Business


Going insane was a luxury. It’s the going, that’s the treat. Going suggests travel, moving. There was no going. The madness was constant and still, sitting there, like a place on a map. The women in the beautifully brutal film 12 Years A Slave were mangled and maliciously intertwined.

It was where they lived, where they were from, born and bred into mundane inescapable crazy.

This young couple is having a great time

The twisted relationship dynamics between the two lead female characters Patsey and Mistress Epps in 12 Years A Slave are a horror. A painfully vivid illustration of the dank gnarly negotiations women had to make with each other to survive the demonic conditions of American slavery. The film fearlessly exposes a suppurating historic wound between Black and White women so wicked and utterly honest, it is both repulsive and liberating to witness.

We see the dark and sweet Patsey, doubly enslaved by virtue of her race and beauty, sway for a moment, let go like a girl, do a slow twirl. She is loose trying to lose herself, and she slips, for a moment, into a trance induced by the sound of her only friend Solomon’s sad singing violin. His is almost music. She is almost dancing. It is all almost a human moment.

All of a sudden she goes limp, drops, knocked back into the terror of her life, by a heavy crystal decanter hurled at her head by Mistress Epps.

All of a sudden, she is once again a battered pile of dirty black woman parts wrapped in rags down on the floor. Mistress Epps is hate, full, guided and preserved by it. Patsey, the object, the affliction. She is, in Mistress Epps molested mind, literally the mistress.

Her husband Edwin Epps is addicted to Patsey, a deadly habit he will not kick, not for his wife, not for her dignity nor her sanity. The Mistress publicly demands Edwin rid himself and her home of the disease that is Patsey. He not only refuses his wife, he comfortably humiliates her.

Claiming his desire for the puddle of nasty nigger wench at their feet. The Mistress is frozen, stunned powerless by her husbands white male supremacy while Patsey is dragged away into darkness.

Patsey and the Mistress Epps personify Black and White American women’s painful slave legacy. American slavery was an insidious economic institution devised to benefit a minority of white Christian men, predicated on systemically preventing others access or the ability to establish alliances. Society has discussed how slavery successfully branded Blacks as inferior and sub-human, yet have we ever fully faced the brain washing, torture and rape terrorism practices slavery inflicted on Black and White women?

Are white privileged women jealous because their husbands had sex and lusted after black women right in their faces?

Do they believe the enslaved black women, purposefully seduced their white men, did they think they wanted to be raped?

Are black women in the eyes of white women, the original whores, the quintessential sluts? A sickening set of propositions, but the institution of slavery was such a sick situation for women to be in.

An evil woman is easy to understand. Mistress Epps makes clear white women bound in slavery were far more complicated than pure evil. She is in a tumultuous rage.

Never ending pleasure in talking to him

A white woman’s rage: privileged with no position, positioned with no power, powerful with no promise of independence, fidelity or safety.

The white woman could not properly direct her rage at her husband, she could not rail against white male supremacy. She too was in hell and Black enslaved women where the only ones in the chambers bellow her. So she sent her rage down and with her hot hate burned what was left of the bitches.

And the black women scorched beyond human recognition were left in pieces scattered and buried somewhere beneath hell. The concept of hell, like slavery, was designed to control and terrorize for eternity. The relationship between the mistress and the slave woman was so poisoned from its inception it could never be healed.

Is this our original sin? Could this be at the root of why Black women were cut out of the American suffrage movement when it came time for voting rights for women? Why many white abolitionist women turned their backs on the violence against southern Blacks to secure their own right to vote?

Black and White American women were doomed from the start, viciously competitive, inhuman maddening

Women’s movements can’t move in America until we have courageous honest discourse about the sadistic historic foundation of the relationship. We were systematically cultured to distrust and envy each other. We were never meant to be sisters.
