iFI Audio Go Blu
Portable Bluetooth headphone amplifier
The Go Blu pocket rocket from iFI Audio is small enough to bring wherever you want to go, and enjoy high-quality audio. It gives you the option to use wired headphones, without sacrificing the convenience of a wireless connection. Whether exercising at the gym, strolling down main street or sitting at your desk, the Go Blu is the perfect companion. It connects wirelessly via Bluetooth and supports all the latest codecs including AAC, aptX, aptX HD, LDAC and LHDC.
Regular wireless headphones integrate Bluetooth procession, digital-to-analog conversion and amplification onto one, standard off-the-shelf chipset. This of course lowers the ceiling as to the quality that can be achieved. Pair a good wired headphone or IEM with the Go Blu to experience how real portable Hi-Fi can sound. It works with Android as well as iOS devices, and basically any other Bluetooth capable device out there. You can even connect it to your smartphone or computer using a cable, if you want to take full advantage of the on-board 24 bit/96 kHz DAC.
With the size of a Zippo lighter and a weight of just 27 grams, the iFI Audio Go Blu slips into your pocket and is barely noticeable.
