Our new GO blu, pocket-rocket portable HD DAC/amp, is diminutive enough to take with you wherever you go! It gives you best sound from wired but 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 favourite coffee shop, the GO blu is the perfect companion.
It pairs wirelessly with your source device via Bluetooth with no need to worry about whether you’ve got the right cable for your Android or Apple device. Just pair … and GO!
That’s less than an AA battery!
Traditional wireless headphones or earphones of any kind integrate Bluetooth processing, D/A conversion and amplification onto one, standard ‘off the shelf’ chip. There is a ceiling to the sound quality that can be achieved.
Team good corded headphones or in-ear monitors, with a separate, high-quality portable DAC/headphone amp, and your sound quality will beat any pair of wireless headphone or earphones hands down.
The GO blu means no compromise on sound quality.
Pair the GO blu to your Apple/Android. Connect your favourite corded headphones to the GO blu and then tuck it away – it’s so petite it will slip into your running gear or suit pocket. It’s also gorgeous enough to show off by leaving it on the table at your favourite coffee shop!
Most pocket-size Bluetooth DAC/headphone amps incorporate all-in-one ‘system on a chip’ solutions to deliver input processing, digital-to-analogue signal conversion and amplification.
Not the GO blu.
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 GO blu uses the same Bluetooth 5.1 as seen in other recent iFi products. Furthermore, we have separated the modules so that every last drop of audio quality is unmatched.
And when you wish, just use the USB-C connection and enjoy High-Res USB audio too!
That’s Paris to New York +
Diminutive. Balanced. Powerful.
The Go blu amp circuitry benefits from symmetrical twin-mono signal paths and utilises iFi’s Direct Drive design concept. Plus it incorporates circuit components of a quality not commonly found in a device of this kind.
This means ultra-low distortion across the entire signal bandwidth. The sound is purer, clearer and more naturally expressive.
The amp stage delivers up to 5.6V, considerably more power than others. It handles tough headphone loads with ease. Auto-gainadjusts output up or down by 6dB to ensure signal strength suits the sensitivity of the connected headphones/earphones.
GO blu‘s ChronoDial is a masterpiece of precision engineering and, just like a Chronograph, it gives you precise, analogue volume control. You can use it to play, pause, and skip tracks forward and backwards and even activate the voice assistant on your Bluetooth-connected smart device. Here’s how it’s constructed:
Whether you use balanced or non-balanced headphones, you get the least noise and best channel separation for the most enjoyable music.
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, this is especially beneficial with high-sensitivity in-ear monitors.
Both outputs are gold-plated to resist tarnishing and thereby maintain optimum contact quality.
With XBass to add back lost low-end grunt and XSpace to widen the soundstage, the GO blu is small on the outside but mighty on the inside. You will be immersed in its majestic musicality.
The X-factor doesn’t stop with the sound. The GO blu is built like a luxury Swiss watch – the volume control has a watch crown machined by a watchmaker for the tightest of tolerances – and has the luxury feel of Mont Blanc, thanks to our French product designer.
Made with the latest, most hi-tech materials and weighing in at a super featherlight 26grams or 0.06lbs, it will be your ‘go-to’ music device.
We use Qualcomm’s new QCC5100 Bluetooth IC in combination with the Cirruc Logic 43131 as DAC to to create an audibly superior ‘Bluetooth engine’.
All the current high-definition Bluetooth audio formats are supported – Qualcomm’s aptX Adaptive and aptX HD, Sony’s LDAC and HWA’s LHDC, regular aptX and aptX Low Latency, AAC (Apple iOS devices) and SBC (the ‘plain vanilla’ Bluetooth codec).
Of the 24-bit-capable codecs, aptX Adaptive and aptX HD support up to 48kHz, while LDAC and LHDC reach 96kHz.
iFi’s ‘Bluetooth engine’ can also be updated over-the-air, so future codecs may be added.
It is a superior method to the traditional single-ended circuit approach. Balanced circuits reduce noise and crosstalk. Less Interference – clearer sound.
You normally find this set-up in products at the higher end of the price spectrum such as the Pro iCAN but iFi is now using this across its range to produce the best quality audio for all our customers.
An important aspect of the circuit design is its direct-coupled nature (no coupling capacitor is present), achieved without a conventionally applied DC servo.
DirectDrive® equals a direct signal path which means less signal degradation. This direct signal path is unequalled in audio and is the reason why the sound is so ‘true’.
TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications.
Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels.
They are pricey but are a perfect addition to our products.
When Taron and Andrew Lissimore started headphones.com, they wanted to create the headphone store they wished existed. As headphone enthusiasts, they wanted a store with 365-day returns.
So they decided they were going to try to make 365-day returns work - no matter how ridiculous it sounded to their wives.
Years later, they're still doing it, and their wives still think they're crazy.
So take some time to get to know your new gear. We want you to enjoy your purchase for years, not just a few weeks. If you're not satisfied, you can return items in like-new condition for up to 365-days.
To get the return process started, you just need to click this link. Enter your order number as well as e-mail address to get it started and after that just follow the steps outlined in the portal (note open-box, special order and sale items are not eligible). A pre-paid shipping label will be generated for you a deducted from your refund after being processed.
After receiving your return label, you will have 7 days to drop off your return with the courier. If your return is not dropped off within 7 days of receiving your return label, a 30% restocking fee will occur. If your return is not dropped off within a month of your label being issued, your return will be rejected.
Your item must be in like-new condition with its original packaging. It must also include all original accessories and manuals. Please add a larger shipping box to protect the original packaging during shipping.
You may choose either a refund or an exchange for the full cost of the item. The refund will be processed on the same method of payment you used to make the original purchase.
A pre-paid shipping label is generated for you. It is deducted from the final refund total after inpsection.

In order to provide a 365-day return policy, we need to take abuse seriously.
We monitor a buyers ratio of purchased to returned products. If it exceeds an internal threshold they will no longer be allowed to place orders with Headphones.com. This includes customers who spread returns across multiple accounts.
We made our return policy to help you find gear you feel great about for a long time. Most people use it exactly as intended. We don't want the handful of people who attempt to abuse our policy to ruin it for everyone else.
If you paid with a cryptocurrency, the returned amount will be equal to the USD equivalent of your payment on CoinGecko.com at the time the refund is processed. The return will be made in the currency of your original order.
Each return is inspected at our warehouse. During busy times these inspections may take a few extra days.
We will notify you by email when your refund or credit has been processed. It may take a few business days for a refund to appear in your account. This is determined by your financial institution.
If you still have questions, please email firstname.lastname@example.org and an advisor will be happy to help.

To that end, all of our packages are shipped signature required with FedEX to make sure your package arrives in your hands safe and sound and if there are any issues, your time isn't wasted.
However, if you are looking to ship to PO Box or APO address, we can definitely accommodate your shipping needs!
