The Oakcastle MP300 may be simple, but it does enough that your phone
doesn't, to fit into certain set-ups.

FULL STORY ======================================================================Oakcastl e MP300: Two-minute review Okay, Ill fess up: this Oakcastle MP300 review wasnt meant to take a month. I thought this super-cheap MP3 player would be a quick in-and-out style of review where Id listen to a few tunes and take it
on a trip, but it ended up being a really useful addition to my audio set-up. Good for it, not so good for my deadlines.

This is the kind of budget music player that a serious music fan would probably ignore does anyone other than wallet-friendly Chinese brands make this kind of tech? Apparently yes, they do actually, but if I can humbly request that we stop that train of thought right now: this isnt any bargain bin buy. Oakcastle is a sub-brand of Majority, a brand audio fans
emphatically know about. So before we get into any of its pros and cons,
youve got an immediate benefit over most budget MP3 players online: you know this one is from a known and trusted audio specialist, with a reputation to uphold and uphold that standing, the MP300 does.

Im not going to pretend that this is the best MP3 player for everyone: it has limited file support, feels quite cheap in the hand, and only offers a fraction of the features that a pricier option would have.

But its simplicity is the point: this is a lovely little digital detox
machine that doesnt make you pay for fancy extras you might not need. Its no distraction machine thatll suck you into a WhatsApp wormhole when youre just trying to put on a song, and its playlists arent so algorithmic that youre only hearing the same eight songs on repeat.

The MP300 became my month-long go-to because I plugged it into my bookshelf speakers via aux, and just left it there. Any time I wanted music, I could easily open up my library and start playing my songs. And I do mean my songs no music streaming here, this is a device for people who own their own music, but dont need to hear it played in lossless.

There are other benefits that bespoke MP3 players bring over using
smartphones for music, and the Oakcastle being so cheap means you can enjoy
it without breaking the bank. Seniors will love it for its simplicity, and
its something children can use to enjoy tunes without priming them for future technology addiction. Get daily insight, inspiration and deals in your inbox Sign up for breaking news, reviews, opinion, top tech deals, and more.

You can use a device like this at night, to put on some soothing Elgar, without a notification or two waylaying your relaxing doze. MP3 players are also nice little running devices, freeing you from your smartphone when you strap on your trainers, though something like the super-small Majority MP3 with its nifty clip might be better for that.

As I say, its not for everyone: if you dont need a standalone music playing device, or conversely you want one thats advanced and full of features, this isnt for you you'll need to look to pricier options from Astell & Kern or FiiO. But theres got to be a sweet spot between those camps who appreciate
it. I certainly like the MP300 a lot. Oakcastle MP300 review: Price and release date (Image credit: Future) Released in February 2026 Listed for
31.95 (about $40, AU$60) On sale in UK, maybe Aus, probably not US The Oakcastle MP300 was released on February 18, 2026, alongside the same-priced MP250 model which has a sports clip and simplified controls.

Online, the MP300 is officially listed at 31.95 (about $40, AU$60), though during testing I generally saw it for a few pounds less. Not by a huge amount
you wouldnt buy a pint with the difference, even outside London but enough to suggest that this thing is rarely at RRP.

Oakcastle, like Majority, generally doesnt sell its products in the US, so dont expect availability there. Some of the brands gadgets sell in Australia, but at the time of writing, the MP300 wasnt available. Oakcastle MP300

Up to 128GB Oakcastle MP300 review: Features (Image credit: Future) 50-hour battery life Custom, simple user interface 64GB storage, up to 128GB more via microSD The Oakcastle MP300 runs on a simple operating system , which feels like a glorified media library. You can see whats currently playing, browse your general music library, make playlists and set up Bluetooth connections.

It does offer a stopwatch and calendar (with no way of inputting dates), but the point of this thing is clearly music. Navigating with the buttons isnt especially fast, and unfortunately theres no music search option (that I
could find).

You get a battery life that, according to Majority, hits 50 hours on a single charge. That seems to match up with what I found its definitely long enough that you dont need to worry about charging frequently.

The MP300 has 64GB of built-in storage, which is plenty if you use MP3. My library was in WAV and didnt fit onto the thing to begin with, so I had to convert them to fit. The expandable storage gets you up to 128GB extra, and you can be sure I made the most of it.

Moving my library over to the Oakcastle was easy: I plugged it into a
computer and dragged and dropped the files into its folder. It wasn't the perfect conversion: lots of album artwork didn't get pulled through, and on the device, songs are all labelled as .mp3. But overall, it was pretty simple and worked fine. Features score: 3.5/5 Oakcastle MP300 review: Design Image 1 of 3 (Image credit: Future) (Image credit: Future) (Image credit: Future)
Nine buttons plus screen Lightweight, but somewhat cheap feeling No IP rating I almost thought the Oakcastle MP300 was a feature phone when I first saw it: it has a similar design, with buttons below a screen and ports on the bottom. But its much lighter than a phone, at 53g theres a good chance your earbuds case tips the scales more than that.

The MP300 is also smaller, at 50 x 101 x 9.5mm, so I could put it in my
pocket without it feeling like a second smartphone. On the bottom theres a USB-C port for charging and data connection, as well as a 3.5mm jack. The right side has a microSD card slot, which is a nice addition.

Despite being compact, the Oakcastle still feels a little hollow it gives a little when you squeeze it, making it feel a little fragile and cheap. Saying that, the textured plastic back makes it feel a little more premium than some of the bargain-basement MP3 players you might find on line.

Accusations of cheap become more well-founded when you move over to the buttons though. Theyre not as sensitive or responsive as youd hope, which slowed down my navigation of the player and constantly reminded me of the
lack of money spent.

If youre a pool-music-listener, I should warn you that theres no official IP rating try to avoid getting it wet or dusty. Design score: 3.5/5 Oakcastle MP300 review: Sound quality (Image credit: Future) Supports MP3, FLAC, WAV No on-board equalizer No higher-res Bluetooth codec support The MP300 supports three file types: MP3, FLAC and WAV. Naturally your sound quality will vary depending on which you pick; I tested all three for scientific purposes, but for general use, I had to use MP3 simply to fit all my music on the speaker.

Theres no equalizer on-board, so youd better like your music how it comes
or, more accurately, your headphones how they come. At least you can use a wired connection to hear, not just via Bluetooth 5.0 (only your basic 'vanilla' SBC streaming is supported, as far as I can tell), although I appreciated having the option to go wireless.

Lets be honest: this isnt an MP3 player youre buying if sound quality is your biggest concern. There are options that cost a lot more which offer extra onboard DACs to level up the audio, streaming over wi-fi and hi-res Bluetooth codec support. So the fact that sound from this thing is pretty basic is part and parcel of the MP300.

There is a built-in speaker here, but its quiet and doesnt exactly sound amazing. For me, it was sometimes a simple reminder that Id forgotten to connect to a speaker, rather than a serious way of enjoying tunes. Sound quality: 3/5 Oakcastle MP300 review: Value (Image credit: Future) It's really cheap Worth buying over dubious alternatives Of course the Oakcastle MP300 is good value; youre paying pennies to get an on-the-go music device.

Sure, it doesnt have many feature of flashy alternatives, but it has storage capabilities and a headphone jack: what more do you need? Thanks to this latter, its probably better than your smartphone for music playing, lets be honest.

Given that Oakcastle is a trusted brand, Id feel safer giving this company my money, rather than any of the even-cheaper alternatives youll find online. Value: 5/5 Should I buy the Oakcastle MP300? (Image credit: Future) Swipe to scroll horizontally Oakcastle MP300 score card

You're getting the basic sound with little ability to change it. Even hi-res streaming is out of bounds.

Value

It's arguably the cheapest MP3 player you should consider buying.

5/5 Buy it if You need something cheap and cheerful If you need something, anything, to play your collection of MP3s (perhaps left over from an iPod Touch?) then this is a solid, budget option. You need expandable storage The microSD card slot is a neat addition at this level, so you can get extra
space but chop and change it around if needs be. Dont buy it if You want control over your sound The lack of an equalizer is one way in which the
MP300 compares poorly to your smartphone. You want high-res output There's no 4.4mm, no Bluetooth Codec support and barely enough space for high-res audio files. Oakcastle MP300 review: Also consider Swipe to scroll horizontally Header Cell - Column 0

2TB Majority MP3 This equally-budget option does things a little different:
it offers less storage space but comes in a smaller body and has a sports clip, making it a handy on-the-go companion. Read our full Majority MP3
review Fiio JM21 If you want a 'proper' digital audio player, this
entry-level Fiio option may cost more than the Oakcastle, but it's still
cheap in the grand scheme of things. It lets you listen in a variety of high-res formats and lets you control your audio to a much greater extent. Read our full Fiio JM21 review How I tested the Oakcastle MP300 Tested for a month Tested on various speakers and headphones via aux and BlueTooth I used the Oakcastle MP300 for a full month before writing this review. I started
the testing by loading it up with my music library, first in WAV and then in MP3. This collection includes a large range of genres, with roughly 3,000 tracks in all.

Through the month, I used the MP300 alongside a range of devices. I connected them to the Samsung Galaxy Buds 4 Pro and Edifier M90 via Bluetooth, and via aux I used the Edifiers, my Sony headphones and my Line 6 guitar amplifier.
