Lightweight and Convenient, the iFi GO blu Bluetooth Headphone Amplifier Allows You to Enjoy Spectacular Audio Quality Anywhere

The iFi GO blu, a revolutionary, portable DAC/amplifier, offers impressive power yet is small enough to take with you wherever you go. 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. It pairs wirelessly with your source device via Bluetooth, so there's no need to worry about whether you've got the right cable for your Android or Apple device.

There is absolutely no ceiling to the sound quality that can be achieved with the iFi GO blu. If you use premium corded headphones or in-ear monitors, your sound quality will surpass that of most wireless headphones or earphones. Just connect your favorite corded headphones to the GO blu and then tuck it away – it's so petite it can slip into your running gear or pocket. It's also gorgeous enough to show off by leaving it on the table at your favorite coffee shop.

With its lightweight, soft-touch polymer enclosure (great for Bluetooth reception, unlike signal-blocking metal), copper-colored trim, and ChronoDial watch crown-style control, the GO blu is a pleasure to use wherever you go. iFi has even 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 from source devices that don't offer Bluetooth connectivity. High-resolution PCM audio data up to 24-bit/96kHz is supported when the GO blu is connected in this way.

iFi implements Bluetooth with a design that is anything but "run of the mill." The use of Qualcomm's four-core QCC5100 Bluetooth processing chip ensures that every current high-definition Bluetooth audio format is supported. This means that every possible source device is handled at the highest audio resolution its Bluetooth specification allows: No other pocket-size DAC/amp delivers such comprehensive codec support, or such high-quality sound over Bluetooth. The GO blu is Bluetooth v5.1-compliant, ensuring the best possible range, stability and performance, and its "Bluetooth engine" can be updated over the air.

Most pocket-size Bluetooth DAC/headphone amps incorporate all-in-one "system on a chip" solutions to deliver input processing, digital-to-analog signal conversion, and amplification. These are simple and cost-effective, but they cannot compare with expertly designed, individually optimized circuit stages when it comes to sound quality. Unique 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 makes full use of Qualcomm's four-core QCC5100 Bluetooth chip and supports every current high-definition format. This then feeds the DAC stage with a Cirrus Logic 32-bit DAC chip at its heart. This is coupled with a customized digital filter to minimize pre-echoes and ringing artifacts, and a precision clock system to ensure ultra-low jitter, thus reducing errors and distortion in the digital audio signal.

The amp circuitry benefits from symmetrical twin-mono signal paths and utilities iFi's Direct Drive design concept – direct-coupled to ensure a clean signal path without any distortion-inducing output coupling capacitors. The amp stage delivers up to 5.6V – considerably more power than other similarly sized devices – handling even relatively tough headphone loads with ease. To ensure that the signal strength suits the sensitivity of the connected headphones or earphones, auto-gain adjusts output up or down by 6dB.

Whether you use balanced or non-balanced headphones, you get the least noise and best channel separation for a pristine listening experience. The GO blu boasts a Pentaconn 4.4mm output, enabling headphones equipped with balanced connectivity to take full advantage of the GO blu's balanced amp design. In addition, the 3.5mm output benefits from iFi's proprietary S-Balanced circuitry. This cuts crosstalk and related distortion in half when used with regular, single-ended headphone connections. (It is especially beneficial with high-sensitivity in-ear monitors.) Both outputs are gold-plated to resist tarnishing and thereby maintain optimum contact quality.

You can use the XBass feature to add back lost low-end rumble, and XSpace will widen the soundstage. In numerous ways, the GO blu is small on the outside but mighty on the inside. Furthermore, it has a watch crown-style control and is made with premium, high-tech parts. Lightweight and easy to use, it will become your "go-to" music device.

Like all Music Direct products, the iFi GO blu Bluetooth Headphone Amplifier comes with the 100% Music Direct Satisfaction Guarantee.

"[When] portability is paramount and convenience is key, you cannot currently better the iFi Go Blu. It levels up your phone's sound with very little effort or added weight in your pocket or strain on your wallet.... Highly recommended."
