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).
20 - 20,000 Hz
Input Connection

Smaller than you think; big sound

May 15, 2015

The Beyerdynamic A200p DAC-amp is a joint product with the digital audio player firm Astell & Kern. It connects to your phone via short, proprietary Lightning (for iOS) and USB (for Android) cables. It charges from a proprietary USB cable as well. The silver circle of the device is the volume control. Several thick rubber dots are supplied to add a "handle" to make the volume disc to turn. The A200p fits inside a small leather case with a belt loop. The logistics of attaching it to a belt and to the phone with such a short cable are problematic, however.

The A200p DAC-amp makes your phone music files sound great. There is more than enough volume -- the volume control silver disc turns multiple times -- to power the most power-hungry headphones, like the 300 ohm Sennheiser HD-650s. The A200p battery lasts a long time, too. It is a great little unit, and is smaller than you think.
