Read our full review here. Blu Everyday IFi's GO blu, pocket-rocket portable HD DAC/amp, is diminutive enough to take with you wherever you go! It gives you the best sound from wired with the convenience of wireless as you no longer need to have a cable connection to your smartphone. Whether you’re exercising at the gym with your Apple watch clocking your every step or catching up on your MacBook at your favorite coffee shop, the GO blu is the perfect companion. Superior Sound, Unbound Wireless headphones or earphones of any kind integrate Bluetooth processing, digital to analog conversion, and amplification onto one, standard ‘off-the-shelf’ chip. There is of course a ceiling to the sound quality that can be achieved. When pairing headphones or IEMs with a decent cable and a separate, high-quality portable DAC and headphone amp, your sound quality will beat any pair of wireless headphone or earphones, hands down. Using the GO blu now means no compromise on sound quality. Go Beyond With its lightweight, soft-touch polymer enclosure, copper-colored trim, and ChronoDial, crown-style control, the GO blu is a pleasure to use. iFi has incorporated a high-quality, chip-based (CMOS-MEMS) microphone, enabling hands-free calls, voice chat for gaming, and access to voice assistants such as Apple Siri and Google Assistant. Further flexibility is provided by the USB-C charging port, which doubles as an audio input enabling USB connection with Hi-res PCM audio data up to 24-bit/96kHz supported. HD Bluetooth 5.1 The use of Qualcomm’s four-core QCC5100 Bluetooth processing chip ensures that every current high-definition Bluetooth audio format is supported. aptX Adaptive and aptX HD LDAC and HWA/LHDC regular aptX and aptX Low Latency AAC SBC (plain vanilla BT) The GO blu is v5.1 compliant, ensuring excellent range, stability, and performance, and its ‘Bluetooth engine’ can be updated over the air. Three Unique Stages: Bluetooth, DAC, and Amp Uniquely for a device of this type and size, the GO blu’s clever design packs in separate Bluetooth, DAC and amp stages, each engineered in distinct blocks to deliver the ideal combination of cutting-edge specification and superb sound. The Bluetooth stage supports every current high definition format and feeds the DAC stage with a Cirrus Logic 32-bit DAC chip. The amp circuitry benefits from symmetrical signal paths and utilizes iFi’s Direct Drive design concept to ensure a clean signal path without distortion. The amp stage delivers up to 5.6V handling even relatively tough headphone loads with ease with auto-gain adjusting output up/down by 6dB as needed.
