It’s a tough one: youwantto upgrade your phone’s sound with one of thebest portable DACsgoing, but you’re still on an iPhone with a Lightning connector and your plan’s not due for an upgrade for a little while – soApple’s newest USB-C totingiPhone 15is apossibility,rather than a certainty.

That’s OK. Astell & Kern’s brutalist, easily pocketable new HB1 DAC (which could even be mistaken for a high-end lighter to the uninitiated) comes with USB-C to Lightning and USB-C to USB-C cables, but if you want to connect to your device wirelessly over Bluetooth, you can do that too!

The product is the HB1, it launched today (October 19), and had we known about it sooner, it most certainly would have featured in our3 USB-C DACs to turn your iPhone 15 into a bona fide hi-res music playerroundup (althoughA&K’s lovely little HC3does feature there) – and likely our mini selection of the3 best wireless DACs to seriously upgrade music from your smartphonetoo.

But I can certainly draw your attention to the AK HB1 now. It is a Bluetooth and USB Type-C DAC/Amp that’s light, portable, and with a powerful built-in amplifier plus a premium microphone.

And it’s not just for your phone! You can connect it to PCs, tablets, game consoles, and more. Via wired USB, it supports Native DSD256 and 32-bit/384 kHz playback and it’s equipped with a renderer function that supports MQA 8X (24-bit/384 kHz) too.

Want to stick with Bluetooth? The AK HB1 accommodates an extensive selection of codecs to deliver smooth playback of high-resolution audio through LDAC and aptX HD codec support, as well as the more common AAC and SBC for PCs and smartphones.

You’ll still need a set of thebest wired headphonesending in either a 3.5 mm unbalanced or 4.4 mm balanced jack (the wireless bit is from the DAC to your device) but this is always the case with such designs and considering the audio upgrades Astell & Kern is capable of, it’s a small price to pay.

Opinion: A&K hasn’t forgotten gaming or in-car use either – and I predict a huge hit

And let’s talk about leveling up your gaming experience, where IEMs and better quality audio are certainly having a moment – just see theRazer Morayor theFinal VR2000for starters.

The AK HB1 offers simultaneous Support for UAC 1.0 and UAC 2.0 for gaming. To clarify: while modern smartphones, tablets, and PCs support UAC 2.0 connections, many gaming devices still exclusively support UAC 1.0 connections (Sony PS5, I’m looking at you). The HB1 caters to both, so you could connect it to yourSonyconsole orNintendo Switch, say, to enjoy low latency, enhanced sound in an immersive gaming session.

The high-quality mic should also ensure crystal-clear voice quality and stability for taking calls while working (or gaming) because it is equipped with Clear Voice Capture technology to suppress ambient noise while delivering clear vocals.

And I haven’t even touched upon the Car Mode! Activate AK HB1’s dedicated Car Mode to enjoy high-quality sound at the wheel. Simply by connecting AK HB1 to your vehicle’s AUX port, its power will automatically turn on/off based on your vehicle’s ignition, thus allowing you to enjoy supercharged audio from your paired devices.

OK, it’s a little more expensive than your standard plug’n’play DAC, at $250 / £259 / AU$489, but then it does so much more. And given its plethora of use scenarios and connectivity options, I reckon it’ll be a huge hit.
