+Tangara is a portable music player. It outputs high-quality sound through a 3.5-mm headphone jack, lasts a full day on a charge, and includes a processor that’s powerful enough to support any audio format you can throw at it. It’s also 100% open hardware running open-source software, which makes it easy to customize, repair, and upgrade. Tangara plays what you want to hear, however you want to hear it.
