Now there's no need to compromise when listening on the move with your iPod or computer. With the iBasso D2 Boa you can bypass the noisy headphone output on your iPod or computer and feed your headphones with a crystal clear audio signal.
The headphone output on many portable devices, such as the Apple iPod and many laptop computers, is noisy and introduces distortion to the audio signal. With a dedicated DAC and headphone amplifier combination, like the iBasso D2 Boa, you can bypass the standard headphone jack on your iPod or laptop and enjoy distortion free audio.

"The results I had with full-sized phones and the line-out on an iPod Touch were actually quite amazing"
"The fact is, once you've got used to listening to a decent pair of headphones through the D2, it's very hard to go back.
"A great sounding portable headphone amp that doubles as an outboard DAC for PC listening. Try it with the right cans, and you'll never want to listen to your headphones without one out again"
CNET Review of iBasso D2 - Impressive
"The D2 deepened and smoothed out the bass, gave vocals a significantly richer, velvety-smooth quality and extended the high-end. The resulting sound is beautiful - crisp, controlled and powerful.
What HiFi? Review of iBasso D2 - Very Good
"The D2 adds greater weight to low frequencies while bringing more detail and verve to the midrange."
Additional Information What is a DAC? A Digital to Analogue Converter takes a pure digital audio feed (in this case from a computer) and converts it into an analogue signal that can be amplified.
Every computer soundcard with a headphone or line level output has a DAC onboard, but in many cases is very poor quality. The iBasso D2 Boa upgrades your portable audio system in one step.
The iBasso D2 Boa combines a high quality DAC and headphone amplifier in one unit, giving you the ultimate portable audio setup.
Why use a headphone amp? A headphone amplifier takes a line level signal and allows you to drive headphones with it. Normally a line level signal would not be powerful enough to drive headphones without amplification.
You can use a headphone amplifier to drive your headphones from many audio sources, such as CD players and portable audio players like the iPod (dock connector cable required).
