After testing the Oakcastle MP300 MP3 player for a full month, it unexpectedly became my primary music source. This low-cost device from Majority’s sub-brand delivers reliable performance without unnecessary bells and whistles, making it ideal for users seeking simplicity.
Quick Overview
The Oakcastle MP300 prioritizes ease of use and affordability over advanced features. It supports expandable storage, Bluetooth connectivity, and a 3.5mm jack, all at a fraction of the price of premium digital audio players (DAPs). While its plastic build and basic controls may deter some, it excels as a distraction-free music companion.
Key Pros
- Expandable storage up to 192GB total
- Bluetooth 5.0 and wired 3.5mm options
- Exceptional 50-hour battery life
- Ultra-low price point
Key Cons
- Budget-feeling construction
- Buttons lack responsiveness
- Limited audio file formats and no equalizer
Price and Availability
Launched on February 18, 2026, alongside the clip-equipped MP250, the MP300 lists at £31.95 (around $40 or AU$60). It often sells for slightly less online in the UK, with limited availability in Australia and none in the US.
Specifications
- Battery Life: 50 hours
- Weight: 53g

Features and Performance
The MP300 runs a straightforward interface focused on music playback, playlists, and Bluetooth pairing. It includes a stopwatch and calendar, but navigation relies on physical buttons without search functionality. Transferring files via USB-C is simple—drag and drop works seamlessly, though album art may not always transfer perfectly. Converting larger WAV libraries to MP3 fits everything comfortably. Battery claims hold up, lasting weeks between charges. Features Score: 3.5/5
Design
Resembling a compact feature phone, the MP300 features nine buttons below a small screen, USB-C and 3.5mm ports at the bottom, and a microSD slot on the side. At just 53g, it slips easily into a pocket. The textured plastic back adds grip, but the lightweight chassis flexes slightly, and buttons feel mushy. No IP rating means avoiding water or dust. Design Score: 3.5/5
Sound Quality
Compatible with MP3, FLAC, and WAV files, audio quality depends on source format and headphones—no onboard equalizer or high-res Bluetooth codecs like aptX. Bluetooth uses basic SBC, but wired connections shine. The built-in speaker is minimal, best for quick checks. This isn’t for audiophiles seeking DAC upgrades or hi-res streaming. Sound Quality: 3/5
Value for Money
At this price, the MP300 outperforms sketchy online alternatives, offering trusted build quality, ample storage, and versatile playback. It beats smartphones for dedicated, ad-free listening. Value: 5/5
Who Should Buy It?

- You want a cheap, simple MP3 player for personal collections
- Expandable storage matters for large libraries
- Digital detox or kid/senior-friendly device appeals
Avoid if:
- You need sound customization or high-res audio
- Advanced features like EQ or premium codecs are essential
