SanDisk Clip Jam 8GB MP3 player - Black

Product Information

If you need a device for your workouts, look for one that’s small, light and ideally water and sweat-proof. The Sony NW-WS415 in this list is a definite winner on that front, and can also be used for swimming if that’s more your thing.

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. There are other benefits: if you’re out and about without your phone charger, playing music through a portable music player isn’t going to drain your phone’s battery. You’ll also be able to take your entire music collection with you, without filling up smartphone storage that you’d rather use for apps, photos and videos. At this price the M11 Pro couldn’t be described as a bargain. But everything’s relative, of course - and if you consider the FiiO’s painstaking specification, premium materials, bank-vault construction and beautifully realised interface, you might consider the asking price could be worse. 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.Storage: 128GB | Screen size: 4.1in | Battery life: 10 hrs Maximum file support: 32bit/384kHz; DSD256 | Dimensions (h/w/d): 12x7x2cm | Weight: 203g

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. 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? The Fiio M11S does an excellent job of gently undercutting its closest rival, the Astell & Kern a&norma SR25 Mk II. You've got so many great options, such great sound, and such high-spec parts that it's very easy to look at the saving and decide it's worth putting into a nice high-capacity microSD card instead of its higher-priced rival.

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. 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. 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.

Sony Walkman NW-WS413 Waterproof 4GB: Best MP3 player for workouts Given its small size, the 12 hours of battery life is very reasonable, and the Ambient Sound Mode is a stroke of genius: it lets you tweak the amount of external noise that’s piped through the headphones, so you don’t get caught unawares by other runners or traffic. Storage space is limited, but for upbeat workout playlists, the 4GB should be more than enough. Speaking of phones, you may find the touchscreen to be a little sluggish, compared to what you’re used to, but with some patience, it’s easy enough to navigate for anyone familiar with the Android launcher. If you can overlook these minor flaws, the Sony NW-A306 is more than worthy of the Walkman legacy and a great way to enjoy your favourite music. Some MP3 players feature Wi-Fi and support for streaming services like Spotify. This varies from player to player, so keep this in mind while shopping if this is an important feature.
