The iFi Audio Zen Air Blue is a powerful and affordable Bluetooth receiver that will allow you to control and send your music to your audio system remotely, directly from your smartphone or tablet. Unlike most other Bluetooth receivers, the Zen Air Blue uses not just a standard SOC (integrated circuit), but a combination of high quality components to deliver the most accurate and musical sound possible. For example, the Qualcomm Bluetooth receiver chip redirects the digital signal to an ESS Sabre digital-to-analog converter. Jitter is then eliminated by a femtosecond clock. An architecture which allows to reach very good sound performances in wireless.
