COZOY / Astrapi

It is a portable headphone amplifier.

■Plug-and-play, no charging required / Overwhelming sound quality improvement
Astrapi is a stick-shaped DA converter and portable amplifier that's plug-and-play, no charging required.
Simply connect it to your iPhone, iPad, Android device, PC, or Mac to enjoy improved sound quality.
By playing music through the dedicated audio conversion IC hidden in this compact housing, you can experience overwhelmingly higher-quality sound than with a smartphone's earphone output.

■The design features a simple microUSB port for digital connection and a 3.5mm stereo mini jack for audio output, allowing you to adjust volume and select songs using the familiar smartphone GUI.
It also comes with a simple clip on the back, making it easy to attach to a pocket or bag.

■Plays high-resolution audio sources compatible with third-party apps
Astrapi is compatible with not only the OS's standard music app, but also third-party high-quality apps. In addition to being able to use the EQ and effects built into each app, you can also play even higher-quality high-resolution audio sources by using apps such as ONKYO HF Player, Radius NePlayer, and Kaisertone, which can play PCM and DSD up to 24-bit/192kHz.

■World's smallest and lightest class / Revolutionary at just 10g
Its revolutionary small size makes it stress-free to carry around. Weighing just 10g and similar in size to a small USB memory stick, it can be used like a short extension cord between your smartphone and headphones/earphones, without using the clip on the back.
