Sony's XM4 headphones are a Prime Day bargain at AU$321 — and I have the perfect excuse for grabbing a pair

I love listening to music on a daily basis. When I'm at home I mainly listen through various Sonos speakers, and on-the-go, I mainly use my Apple AirPods Pro 2.

I've always wanted to listen to high-resolution audio when I'm out and about, but it's not always so easy. My iPhone 15 Pro is technically capable of supporting high-resolution audio, but I need both a streaming service that supports the format, and an external digital-to-analogue converter (DAC) to do so. Not to mention a pair of good quality headphones that can be connected via a physical cable.

<p>High-resolution audio can't be achieved using wireless headphones, and while this Sony set is, it also comes with a 3.5mm aux cable to connect them to a source component. Despite a newer model being released (which is still fantastic) the Sony XM4s are an outstanding pair of headphones that combine an engaging, detailed sound with effective noise-cancellation and supreme comfort. The swivelling ear cups means more travel-friendly than newer models, making them perfect for reproducing high-res audio on the go.  <p><strong>Also consider: <a href="https://target.georiot.com/Proxy.ashx?tsid=8428&GR_URL=https%3A%2F%2Famazon.com.au%2FSennheiser-Momentum-Special-Headphones-Metallic%2Fdp%2FB0CCRZPKR1%3Ftag%3Dhawk-future-22%26ascsubtag%3Dhawk-custom-tracking-22"><strong>Sennheiser Momentum 4 Wireless | AU$625 <strong>AU$350

<p>Amazon Music Unlimited has a large library of songs and albums in what it calls 'Ultra HD'. What this really means is songs that can be streamed and downloaded in better-than-CD quality (24-bit/192kHz for all you number fans). This essentially means songs in Ultra HD will have more data than what you get from CD recording, i.e. more detail.  <p>Amazon is currently offering 5 months of Music Unlimited for free (everyone can get 1 month free regularly) for Prime Day, making it easy to access high-resolution audio. This offer ends <strong>July 23.

<p>The final piece of my personal, portable high-resolution audio journey is the iFi Go Link USB DAC. This dinky little dongle will plug into my iPhone 15 Pro via its USB-C connection, and I'll plug the Sony XM4s into the 3.5mm headphone output. The iFi Go Link supports hi-res music files up to 32-bit/384kHz and DSD up to 11.2MHz (DSD256), which admittedly is higher than the output of Amazon Music Unlimited. Because it's also a headphone amplifier, it will also greatly improve the quality of music that isn't classed as high-res, and thanks to its small size, is incredibly easy to take with me wherever I go.  <p>My colleagues at <a href="https://www.whathifi.com/reviews/ifi-go-link">What Hi-Fi? bestowed a full five stars upon it in their review, which is what gave me the full confidence to buy.  <p><strong>• <a href="https://www.techradar.com/audio/3-usb-c-dacs-to-turn-your-iphone-15-into-a-bona-fide-hi-res-music-player"><strong>3 USB-C DACs to turn your iPhone 15 into a bona-fide hi-res music player
