If you’re looking for the simplest way to listen to Apple Music Lossless, then the company’s own $8 dongle is hard to beat in terms or quality to price. But it has a maximum resolution of 24-bit/48 kHz. If you want to break into Hi-Res Lossless then the KA11 from Fiio — with support for audio at an eye-watering 32bit/384KHz — is the easiest way. At $30, it’s also pretty affordable, too.

Fiio’s years of experience making portable hi-fi has been distilled into this tiny little dongle. Available in both Lighting and USC-C models (love the color of the Apple model), the KA11 packs a lot of punch for something so small. On top of the support for extremely high audio resolutions, the KA11 also has a much higher output than most adapters — including Apple’s. The result is much louder music than your phone offers for most headphones, and with a better DAC like this, you’ll notice a significant improvement in your audio system. If you already have a pair of expensive headphones with a low sensitivity (as many higher end models tend to be) then the KA11 will likely still be able to drive them. You might even consider pairing it with a headphone amp for even more power.

This little dongle isn’t restricted to phones: the USB-C model is compatible with laptops and PCs, too. In fact, it’s likely a decent upgrade over the built-in sound for almost anything you plug it into. That’s true for all of the products recommended in this guide, but you might be surprised to find that something this small can give your PC’s audio system a serious boost. If there was a minor negative, it would be that the KA11 doesn’t support headset microphones, so if you were hoping to be able to handle calls with your headphones then bear that in mind.

With the KA11 being so small, there are no physical controls, so you’ll adjust volume directly on the phone or computer. The only feedback you have is a single LED that will change color depending on the audio it’s receiving (yellow indicates Hi-Res). Fiio also has a mobile app to access additional settings for its mobile products which, right now does include the KA11, but only on Android at time of publication.

While most Android devices support some form of aptX, your PC might not. If you have an iPhone, it definitely doesn’t support aptX and neither will any Macs — Apple devices only offer standard Bluetooth with AAC encoding (320 kbit/s max bitrate). If you want to make sure you’re getting more bits (up to 430 kbit/s) out of your music, across all your devices, Creative’s BT-W5 Bluetooth adapter is both practical and affordable.

The BT-W5 offers aptX, aptX HD and aptX Adaptive (which supports up to 24-bit/96 kHz) and it’ll automatically choose the best one for your headphones. Once you pair them with the adapter you can plug the BT-W5 into any music source with USB-C for improved Bluetooth audio — there’s even a low latency mode perfect for streamers or playing games on Switch, for example, without any lag.

If you have an iPhone with a Lightning connector, the BT-W5 won’t work without an adapter, but it’s a neat way to get the most out of your headphones without having to upgrade everything else. The BT-W5 can remember up to four sets of headphones, too, so if you have a pair for the commute and another set for the gym, just plug in the dongle and you’re all set.

While you can squeeze an impressive amount of audio tech into a headphone adapter, a slightly bigger device affords a decent step up in both specs and features. Moondrop’s Moonriver T2i DAC is slightly larger than a pack of gum, and it has a stylish design that doesn’t look like a boring, generic dongle.

Importantly, the Moonriver T2i builds on the success of the company’s Moonriver 2 DAC. The “2” partly refers to the use of dual DAC chips here, which delivers a “balanced” signal. Each channel can handle up to 32bit/384KHz resolution and there are two headphone ports. One for standard 3.5mm headphones and another for 4.4mm connections — making use of that balanced output. If this is your first step into the world of Hi-Fi DACs, you’re totally fine with 3.5mm headphones, but some prefer the 4.4mm connector as it provides more power and potential signal benefits, especially if you’re using a headphone amp.

With the Moonriver T2i you have a couple more practical advantages. For one, there are physical volume controls on the device itself. If you ever felt that the 16 levels of loudness on the iPhone (I just counted) weren’t enough, then the 100 steps of adjustment on the Moonriver T2i (via companion software) eliminate any worries about setting the music to the perfect level. If your headphones have an in-line microphone, the good news is that this dongle will pass that through to your phone or PC so you won’t need a separate device for calls.

Most importantly, the sound that comes out of the Moonriver T2i is bright and bold. You’ll hear audiophiles talk about sound stage, detail and width, all you need to know is that this DAC ticks off all the buzzwords and serves up bright, robust sound that’s going to make any lossless/hi-res music really shine.

Outputs: 1x 3.5mm singled-ended, 1x 4.4mm balanced | Inputs: 1x microUSB, 1x 3,5mm coaxial, 1x optical, 1x USB-C | Max file support: 32-Bit/768kHz | Bluetooth: No | Weight: 10.8 ounces

If you’ve had some experience with DACs and are looking to ratchet things up a notch or three, then the Mojo 2 from British company Chord wants to have a word. At $650, this is definitely in the high-end price range, but the experience and features it offers make it worth considering for serious audiophiles. But the brains behind the Mojo 2 have been making digital to analog converters pretty much since there was digital music to even convert. That experience is what makes the Mojo 2 a favorite among music fans.

Most options in this guide are designed for mobile devices first, the Mojo 2 is more of a hybrid device. The mobile dongles above all take their power from the player you connect them to, which is convenient, but obviously is less kind to your phone’s battery life. The Mojo 2 has an internal cell so won’t tax the one in your phone or laptop. It’s small enough to be portable, but substantial enough to live on your desk.

Unlike most DACs that use off the shelf chips to handle the digital-to-audio conversion, the Mojo 2 uses field programmable gate array (FPGA) technology to create its own custom “chip.” It’s also powerful enough to act as both a DAC and a preamp, driving even power-hungry headphones with ease. We’ve seen FPGA gain popularity in gaming circles for its ability to imitate various consoles, but that same flexibility is what makes it interesting to the audio engineers at Chord.

If you need something that’s capital L loud, then the Mojo 2 will not disappoint. Proceed with caution here. It’s actually powerful enough to drive two pairs of headphones at the same time and has two 3.5mm ports so you can do exactly that. The curious circular buttons can also be used to change sound profiles with an excruciating level of detail.

The Mojo 2 has standard USB-C, microUSB, optical and coax inputs so it’s more flexible than a lot of its competition in this regard. Although it’s worth noting that you can only charge the Mojo 2 via microUSB. Of course, there’s a cable provided for this, but if you’ve fully made the switch to USB-C, it’ll mean you have to guard the charging cable closely.

Outputs: 1x 3.5mm singled-ended, 1x 4.4mm balanced | Inputs: 1x USB, 1x optical, 1x coaxial, 1x AUX | Max file support: 32-Bit/384kHz | Bluetooth: No | Weight: 2.51 pounds

If you do most of your listening at home, the K7 from Fiio is a great place to start. The world of desktop DACs and headphone amplifiers could fill its own guide, but the K7 is both capable, feature-filled and reasonably priced. It functions as both a DAC and a headphone amp, making it a solid all-in-one solution for audiophiles building a home audio system.

With phono, coaxial, optical and USB inputs, the K7 from Fiio is able to handle music and audio from almost any high fidelity source. Most traditional desktop audio interfaces support playback of up to 24 bit/48 kHz, the K7 can handle files all the way up to 384 kHz at 32-bit – perfect for those who demand a better DAC for high-resolution files, whether you’re listening via headphones or a full audio system.

On the front you’ll find two inputs: a 1/4-inch jack and a 4.4mm balanced headphone port along with a big ol’ volume dial. While its Hi-Fi aesthetic might not be the most razzle-dazzle, it does have an RGB LED around the dial to give it a pop of color (it also changes color depending on the “quality” of your audio source).

There are two versions of the K7, and if you plonk down another $50 you get Bluetooth receiver functionality. This doesn’t mean you can connect wireless headphones, rather you can listen to music from wireless sources, such as your phone while maintaining a physical connection to your PC. If your phone can serve up music in higher-resolution codecs like aptX HD, aptX Adaptive or LDAC (or if it can’t, read about the BT-W5 above) you can listen to it through the K7.
