More Bass

A bass boost has limited ability to increase the intensity of low frequencies, and does so by only a small amount. The ZO2 significantly increases the intensity of low frequencies, making them over 4x louder. In the audio world, that's a big number especially when it requires almost 100x the acoustic power output to achieve.

Deeper Bass

Not all speakers - especially those in headphones and earphones - aren capable of reproducing bass efficiently. Due to their small size, physical limitations prevent how much and how well they can reproduce low frequency sound - until now. ZO2 does what experts claim couldn't be done. By precisely controlling power delivery, ZO increases the efficiency of speakers by extending their response to lower frequencies.

Controlled Bass

When bass boost is on, more power is required to reproduce the low frequencies. But since your player's output is limited, it gets that extra power by redirecting it from the mid- and high-range frequencies. So to get slightly more bass, you sacrifice the quality of everything else. But ZO2 has the raw power to not only give you unparalleled levels of bass, but to reproduce the low frequencies without sacrificing the mids or highs.

Customized Bass

With the 32 built-in Sound Signature Tuning (SST) profiles, you can perfectly tweak ZO's sound characteristics to achieve the ultimate entertainment experience. At the heart of ZO is the LightBar display, which colorfully expresses the selected SST profile.

Real Bass

Most bass boosts and bass enhancement technologies exploit a psychoacoustic effect known as the missing fundamental to create the illusion of bass. But ZO's bass is 100% analog (i.e., the real deal), as we believe there can never be a true substitute for the real thing.

More Than Bass

During the recording process, a high-quality media file is created (represented in the circle as 100% of original). As this media moves through subsequent stages, a spiraling plunge in sound quality occurs. By the time audio reaches the end listener, more than 90% of the original sound fidelity is lost, resulting in flat, lifeless sound, listener fatigue, and even potential hearing damage.

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.
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.
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).
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.
Input Connection
This is the manner in which the headphone amplifiers receive an input audio signal.
Input Impedance
This is the input impedance of the headphone amplifier.
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
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.
Output Power
This is the output wattage of the headphone amplifier. It is measured in mW.
Output Impedance
This is the output impedance of the headphone amplifier.
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.
Width
The width of the item from left to right (side-to-side) measured in inches.
Height
The height of the item, measured from top to bottom, in inches.
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

DAC Specifications

Maximum Output Voltage
This is the maximum voltage that the amplifier or preamplifier is able to output.
Output Impedance
This is the amount of impedance that the microphone allows.
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.
Frequency Response
The range of frequencies the speaker 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).
Crosstalk
Crosstalk is defined as the unwanted transfer of signals across communication channels. The higher this number is, in dB, the better crosstalk rejection the DAC is capable of.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
Digital Inputs
The type of digital inputs the digital-to-analog converter features.
Jitter
Jitter is a deviation in or displacement of the pulses in a high-frequency digital signal.
Line Level Outputs
The type of analog line level outputs the DAC features.
Sample Rate
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.

Great Device a must have

September 29, 2013

The digizoid Zo 2 is a must have for improving the quality of your music. I have had this product for some time now and i do say it's worth getting. Where it lacks in features it will make up in the way your music sounds. the only two complaints I have about this product is the battery life (6 hrs) and that there is only one switch on the side one is really needed but another would have been nice. I as well have to say this device performed best on my apple Ipod and didn't seem to work as well on my Droid razrm

Really performs

February 7, 2013

I bought this 3 months ago for my earbuds that just werent getting enough juice from my Galaxy. I was very skeptical at first, with all the different amps I saw available. I use to have a very small amp I bought for about ***, but after I went through two of those I decided I didnt want to work with that brand anymore. My main goal was to try and get clear, deep bass, but not ruin my highs and mids. I am happier than I thought I would be. My AKG earbuds now sound better than any other headphone I have heard. and ive heard 2 and **** buds too!
