The Best Headphone AMP under 100 Dollars In 2020

Best headphone amp under 100

Headphone amplifiers – widely known as amps – reveal the true essence of your music. Even the greatest headphone is likely to gloss over one or other shortcoming: loose bass, recessed mids, sibilant highs, lack of details. A headphone amp makes up to some extent for the missing link in the chain of satiating audio. The basic amps simply substantiate the power of audio from your source and that alone fills in the gaps. But the exemplary ones create an accurate reproduction, making the best out of the audio they get.  But do note that if your headphones are harsh then it’s likely that those faults will be magnified. If you are a novice, you might be looking for headphone amps under 100 bucks to tide you over until you become a connoisseur of good music. What else could these affordable sets offer?

  • Pint-sized: Many of these headphone amplifiers under $100 are compact and thus, highly portable. They can be wound with your phone or clipped on to clothes. The 4-channel amps redefine the scale with their puny dimensions. They can be accommodated amidst a bevy of home studio equipment.
  • Audio Augmentation: Say you have a set of distinguished headphones but they aren’t as loud as you would like. Or you have a kicker can but the details are not forthcoming. Let the headphone amp take over and make your life easier. We are not saying that they will magically transform your badly formatted audio. They will bring out the best of the good ones. Option like extra bass can add zing to the mix.
  • Demolish Distortion: Many headphones become sibilant at high volumes. Headphone amps with good Sound-to-Noise Ratio (SNR) reduce the distortion to give you a cleaner, straightforward sonic output. This is best tested at high volumes as the moderate volumes are usually protected from distortion in headphones also.
  • Impedance Importance: These headphone amps under 100 bucks support a wide range of headphone impedance. This is an important factor is determining which headphones these amps can drive. Wider the range, the more headphones these amps can boost.

1. FiiO E6 Portable Headphone Amplifier

Best Headphone AMP under 100FiiO has a stronghold in the headphone amp arena. Reason being, they have a varied merchandise spanning price and features widely. There’s choice for everyone and it’s not surprising that they have a few bestsellers under $100 mark as well. FiiO E6 has succeeded its illustrious brother, the E5 headphone amp and pulled a swan/ugly duckling scenario in terms of spec.

FiiO E6 headphone amp has shed half the weight of E5 by investing in a flexible plastic shell. It helps that E6 looks smarter than a metal trinket hanging on your headphones. E6 also offers more options for customizing the audio. Instead of the single power boosting setting on 3dB in E5, this headphone amplifier has 3 added EQ settings: -3dB, 3dB and 6 dB. 3dB considerably boosts the power and brings out the rumble of bass and crispness of mids. At 6dB you would expect your audio to be sibilant, but FiiO has been proactive. This setting does not inflate the bass, rather it boosts the entire spectrum so that it sounds natural, just with more power to it. This maintains the tonal balance and keeps your headphone from sounding crass. The -3dB setting is for unbalanced headphones. The reduction in power tones down the details that muddy the sound. These 3 modes make FiiO E6 compatible to a wide array of headphones: the good, bad and ugly. This headphone amplifier has higher gains and Sound-to-Noise Ratio (SNR) than E5. E6 works on a LiPo battery which is good for 10 hours on a single charge. Two sides of the amp mount the port for jacks from headphone and audio source. The other two sides have power and volume controls. E6 also has a switch to lock the controls so that you don’t power it off or change volume or modes accidently. It comes with a removable clip to attach to clothes, a lanyard loop on one edge and the option to tie it to the cellphone.

FiiO is a favorite toy with the audiophiles. E6 headphone amp is the Holy Grail of for the shallow pocketed audiophiliac utopia. It rules over our best headphone amps under 100 dollars list.

Or do you like to fiddle with different kinds of headphones and find it troublesome to unplug and connect a new headphone to the amp every time? Behringer HA400 4-channel headphone amp allows you to connect up to 4 headphones to play pumped up sound. Behringer has managed to bundle this operation within a 13 ounce package.

HA400 headphone amplifier is customized for studio applications but nothing is stopping you from getting one of these to amuse yourselves. It draws power from a 12V adapter which is included in the box. This eliminates the constraints of battery.  HA400 is not meant to be portable so not being battery-powered is an advantage.

Each user out of the 4 can set their own volume because each one is allotted a dedicated stereo amp on the HA400. Although you may look at this headphone amp as an audio distribution system, it also makes sure that its power inflation does not negatively affect the audio.

3. FiiO E10K USB DAC and Headphone Amplifier

Best Headphone AMP under 100FiiO E10K USB DAC and headphone amp recreates the warm smooth sound of E17 but at a much lower price. The cost is that this is not portable. E10K is run by a USB port that can connect to your audio source like PC to draw juice.

4. Creative Sound Blaster E1 Portable Headphone Amplifier

At a mere 25g this headphone amp can be clipped to your clothes and carried around. It also has two separate op-amp circuits driving two 3.5mm ports, so it amps and splits your audio so that two headphones of similar impedance can share. Nifty, we call it.

There’s a lot to gush about with Creative E1 headphone amplifier. It houses a USB sound card which takes over the burden of sound processing from the connected PC.  It has a micro-USB port which doubles as charging point and two 3.5mm ports. E1’s personal sound signature is full of details. It works on tautening up the mids and highs. E1 headphone amp can handle headphones with impedance up to a whopping 600Ohms. It is compatible with audio up to 44.1Khz/24bit which is not as good as FiiO E10K.Outside of PC connection, E1’s signal processing capabilities are limited to amplifying. When coupled with the SBX Pro Audio Suite, it implements virtual surround sound, bass thrust or equalizing. It also provides the ScoutMode for gamers which brings out the sound effects and helps you with positional audio. Creative E1 headphone amp houses a mono microphone which would perform marginally better than the connected device’s mic. It survives on a Lithium battery that directs it for 25 hours on a single charge.

Creative Sound Blaster E1 headphone amp has a droolworthy repertoire except for the cap on audio quality it can support. But that’s not reason enough for it to be not on our bestheadphone amps under 100 bucks.

5. FiiO A3 Portable Headphone Amplifier

Best Headphone AMP under 100FiiO A3 headphone amp (also fondly christened E11K) packs a punch in a mobile package. It is an upgrade from E11 and compares favorably with devices like E18 and E6. Like E6, it has a bass boost control that adds 3.5dB at 60 Hz and keeps the bass from bloating and bleeding into mids. Additionally, A3 also has a gain switch that allows you to toggle between low and high gains based on your headphones. Building over the strong foundations of other version of FiiO amps, A3 grabs itself a spot on our top 10 list.

A3 headphone amp is roughly shaped like a hip flask with the volume ALPS potentiometer serving as the cap. Volume knob is much easier to operate with one finger. Because of the sloping side design accidental volume change is discouraged. A1 has the line-in and line-out ports symmetrically on either side of micro-USB port used for charging. This is a detour from the conventional design but you get used to it. The good news is you can continue using the headphone amp while charging. Battery can hold up for 16 hours and takes 4 hours to charge. FiiO A3 is built around the idea of being a neutral amplifier. On the normal setting it simply magnifies the audio, bringing out the finer features as the volume increase. With the bass boost on, there is a brightening of the response that arouses the impression of a wider soundstage. Even at low gain setting, you will not feel that your device is under-driven. High gain setting is for the truly terrible earphones that sound like they are under a pool. A3 headphones amplifier can supply headphones in the 16 to 150 ohms impedance range. It does a thorough job of eliminating electromagnetic interference, maybe even better than E18.

6. Pyle-Pro PHA40 4-Channel Stereo Headphone Amplifier

Best Headphone AMP under 100Pyle-Pro PHA40 4-channel headphone amp is comparable to the Behringer HA400 amplifier. Only PHA40 is cheaper and performs the same functions, provided you get a proper piece of the amp. It splits the incoming audio and amplifies it for 4 different headphones with individual volume profiles. The confounding part is how small this device is. Its pygmy sized structure can hide in an unobtrusive recess in the living room and power 4 headphones for activities like watching TV.

Pyle-Pro PHA40 has to be hooked to a 12V adapter for charging. It does not lean on any battery for power. It sports the ¼ inch TRS ports. The trick is to find the right adapter than can make proper contact with the ports. Once you do, you are all set to go. It is not an audiophile amp. PHA40 simply adds power to the headphones and allows louder volumes. There’s no processing or straightening of distortion. Whatever you play, you can play it louder and share it with 3 more people. Most likely, you will never hit the max volume on this headphone amp because it adds opulent power to the audio. The build of this device is solid. It will stand the torture of continuous use by all sorts of audience.

Pyle-Pro PHA40 4-channel stereo headphone amplifier is a feisty device that does its basic duty at a minute footprint and price.
