Headphone Amplifier Specifications

Amplifier Style
Some headphone amplifiers are designed to be portable and others are meant to be placed on a desk. This will tell you what style of amplifier this item is.
Portable
Digital-to-Analog Converter (DAC)
A Digital-to-Analog converter (also known as a DAC) converts a digital audio signal into an analog signal. This is especially helpful for listen to music from digital sources, such as iPods and smart phones.
No
Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
10 - 100000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
<0.009%
Input Connection
This is the manner in which the headphone amplifiers receive an input audio signal.
3.5mm Mini-Jack
Input Impedance
This is the input impedance of the headphone amplifier.
16-300 ohms
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
3.5mm Mini-Jack
Number of Outputs
Some headphone amplifiers have a built-in splitter so multiple pairs of headphones can be connected to it. The number specified here is the number of headphones that can be connected to the amplifier.
1
Output Power
This is the output wattage of the headphone amplifier. It is measured in mW.
16-150 mW
Output Impedance
This is the output impedance of the headphone amplifier.
16-300 ohms
Power Requirement
This is the required way to give the unit power. Common power sources are 120V AC (Common house plugs), batteries, or a combination of the two. If the headphone amplifier uses batteries, this will list the type of batteries that are required. Please refer to the description to find out how many are required for the unit to be properly powered.

I had used the FiiO for years and bought this one as a replacement. Works well with the added volume I need for headphone use. So far, so good with this unit, and very small and portable to use (and lose) so keep an eye on it when traveling.

pretty good

March 30, 2013

When ordering I originally had little expectations for this amp. Cheap price, small unit, how powerful could it be? The unit is built fairly solid. Also I have tested this on several over the ear, in ear, and just all around different situations like multiple outputs. Overall for the price this is a very good value. Under certain situations like spliting to 2 or more unit did it really have an impact on loudless. With thatbeing said the amp cleans up output greatly. For audiophiles like me this is great! The rechargeable battery lasts quite some time on a single charge. Overall yes I would definitely recommend this amp over more expensive units because of the price vs quality. This tiny unit will greatly clean up output while upping output a tad.

These little guys are awesome!

March 12, 2012

I wish Sonic was carrying these when I bought mine. I have two of these which I use to amplify the the headphone-jack output of an mp3 player going thru an 3.5mm-to-RCA Y-connector into the RCA input of a car amplifier (mp3 mounted on handlebar of a MoTo going to a car amp). Especially if you have to branch the two outputs further into 4 outputs for a 4-channel amp, because doing so further halves the voltage. The battery-life on these things is friggin' great. I'll forget about charging it for a long darn time until one day it shuts-off, and I go "Oops!". They seem to stay charged for quite a long time during periods of no use as well.

Good little amp

June 4, 2013

This amp is a pretty good value for the money. It really gives my M50's the extra volume and bass they need. The battery lasts a good while too and it feels pretty solid and well built. Good product would buy again.

Good When it Works

July 22, 2013

I had purchased the amp to boost sound from a Bluetooth device to my car stereo. It defiantly did the job just fine being compact and everything. The amp only lasted a couple months before it had stopped putting out sound. The buttons still lit up but that was all it did.

headphone amp

February 7, 2013

I have never written a review on any product. This one has me impressed! I was not expecting too much, but it really works! All i wanted was a little boost so i gave it a try. I works great and it works even better if u can have it charging at the same time you are using it. works great on headphones and well as a axillary input.I would recommend it to anyone wanting a boost in their sound.I use it all day in my work truck, and at home on my headphones. I don't know about the battery life, but others use aa battery's. I just didn't want to mess with them. Great product for the price!!

Great product, small and light weight. Bought mine for use with my headphones while watching tv, because the signal coming from my TV jack was at a set volume. This product worked great, now I have more than enough volume and the sound is much better. I even use with my ipod...great sound improvement.
