We tested the player with multiple pairs of headphones across multiple price ranges, and were stunned with the clarity and exceptional quality of the audio. There’s a reason the Onkyo DP-X1A sits atop this list – it’s a beast in the portable audio world. Others might not have a great deal of space on their phone if it's an older model, so want to store music elsewhere, and some people might not want to use up battery or data when they're on the move.

There's lots to love here including an Android 10 operating system with a touchscreen that's smooth and responsive, a punchy, controlled and detailed sound and a premium build. We make sure to test each product against its chief competitors too, so you can be sure that if we say so, the product is the best bet for the money. We live with these players for well over a week and run them in religiously so that the components have 'bedded in' before we commence our tests, and we don't finalize our testing until we are certain of the sound quality. We test dozens of hi-res portable music players every year at TechRadar, and that means we know exactly which features, specs, file support and wireless audio codecs to look out for.It's important for us to compare the performance of these players against the claims made by their manufacturers, which is why we take the time to make sure the stamina, durability, connectivity and sound quality claims are legit.

You don’t have to listen long, hard, or through especially accomplished headphones to realise the M11S is the real deal. In every meaningful music-making respect, it has skills – and in some areas, it’s a genuine expert. This is a small, light and stylish music player with a simple matchbox-like design and a big, wide screen. It's an upgrade on Cowon's previous MP3-player model, this time with a volume dial, Bluetooth and more features. The M11S is insightful enough to make minor or transient information apparent, and it can describe the most nuanced dynamic variations in a solo instrument with ease. It has more than enough headroom to dispatch the big dynamic shifts with no difficulty, and it can also describe a big, wide and properly defined soundstage. The treble is perhaps a little on the bright side, but not so much that we'd consider it a deal breaker.

Some people enjoy listening to MP3 players when they work out, so they don't have their phone with them. Whether that's also to keep calls and messages at bay or keep their phone safe. For many people the convenience of MP3 –you can fit more into your device's storage, streaming uses less mobile data and you don't need a really good internet connection – outweighs the loss of sound, especially if you're listening on the move. But MP3 is a fairly old tech now, and there are better options: Lossless Audio and Hi-Res Audio.

Customer reviews

Still, she warned of some weakness in the product, including the design of the virtual world that doesn't encourage "movement through the world and discovery of the content." The interface is easy to control. Tap through options using the touchscreen, and select the music you want to listen to. It could be more responsive, but you get used to it. Battery life is around nine hours, which isn't amazing, but not terrible either. Mattel introduced Barbie in 1959, and she has been the No. 1 fashion doll for the last 49 years, according to the company. But Barbie has faced declining sales in the last five years in the face of new technologies and newer, racier rivals like Bratz.

Where the NW-A306 is let down is not in its music-playing skill, but slight niggles with its all round usability. During our testing, we found that the menu could be a little unresponsive, the battery longevity would vary and it surprisingly sounded like it struggled when playing a standard 128kbps audio file, which all together let down our all-round experience just a tad (well, by half a star to be exact). But there’s no denying that the positives vastly outweigh the negatives here. Although it hasn't been shouted about, four new and quite different-sounding DAC filters are also onboard, which will work if listening in 24-bit/192kHz or less PCM (although they won't work in MQA and DSD formats) and they certainly add value and scope for customization at the level. If your budget stretches to this player and not a penny more, you won't be disappointed. And there's style to match the substance, with manufacturers also competing on design to deliver players that look as good as they sound. Fan of brutalist architecture? Astell & Kern is the name for you. Something a bit more colorful? See SanDisk or Sony. Want something about the size of a matchbox? Cowon's Plenue D3 is the one – see them all in our guide above. Why do people still use MP3 players?As the name suggests, Lossless Audio doesn't sacrifice any of the musical information: the successors to the WAV format used in CDs, which is also lossless, use more advanced technology to take the audio information and make the file smaller without compromising on quality. There are several versions of Lossless Audio including Apple Lossless, FLAC and WMA Lossless, and as you'll see from our guide above you'll often find that the best MP3 players support at least some of those formats.

MP3 players won't suit everyone, many prefer the convenience of having all of their music on their phones, but there are plenty of reasons why an MP3 player is a great idea for some people. Is MP3 quality as good as CD?

Another reason is that not everything you might want to listen to is available on the various streaming services –and not everything that's there today might be there tomorrow, because songs and even artists come and go. By synchronising an MP3 player with your desktop music collection you can always be sure that you can hear what you want to hear. A big bonus for many people is that with your own music collection, you don't need to pay a monthly subscription to listen to it, or to listen to it without advertising. The player is built with a full version of Android, complete with Wi-Fi connectivity and the Google Play Store, which results in it being kind of like an Android version of the iPod touch, able to do much more than just play music. However, the Onkyo DP-X1A is built for super-high-quality audio, and it's an absolute dream. It supports a range of music formats, including FLAC, OGG, WAV, MP3, ALAC, and more. In terms of hardware, the device has two chipsets, one to power the overall device, and one to handle the DAC and amplifier – resulting in a noise-free experience.
