The MP100 is undoubtedly a perfect electronics device to take your favorite songs nearly wherever you go. I can easily make a list of things to love about this music player but it also has a few shortcomings that should be taken into consideration. Here’s a closer look to the plus and minus of this tiny MP3 player.

Oakcastle MP100 Pros

  • Portable and Lightweight

Specifically designed with sports in mind, the MP100 delivers a compact and lightweight frame. Weighing only 27 grams way more lighter than RUIZU M17 Mini Portable Sport MP3 Player that weight 70 grams, carrying the device won’t be a big deal. Besides, it also has quite small dimensions that can easily fit in your suitcase, pocket, or even slip on your belt. The player comes in handy to accompany your outdoor or indoor activity.

  • Rechargeable Battery

Listen to your favorite songs without worrying about battery life as it features a 300mAH battery that lasts up to 30 hours. Don’t worry about dead battery as it can be recharged thanks to a micro-USB charger included in every package. You can easily recharge the battery from various devices like computer, laptop, or USB adapter.

  • Full Set of Features

Another good thing to love about the MP100 is adjustable features. Despite its tiny size, this music player supports several functionalities like sound recorder, FM radio, and Bluetooth. Not to mention it comes with an expandable SD card slot that can be upgraded to 128 GB. Can you imagine how many songs can be stored in this mini device?

  • Water Resistant Silicone Case

The MP100 is not designed to be water-resistant but it comes bundled with a water resistant silicone case that lets you carry this player in all weathers. Even if you want to enjoy a party by the pool, the silicone case ensures your music player is safe.

Oakcastle MP100 Cons

  • Too Small

On the one hand, designed to be compact and lightweight is a good thing. On the other hand, it can be a disaster especially if you are not careful enough in keeping the device. It can easily disappear and finding this tiny device can be a real struggle.

  • No Dimmable Display

This player doesn’t feature dimmable display. In the event you need to use the device in the darkness, the color LCD screen can be too bright and irritating to eyes. Unfortunately, it doesn’t give you other options.


All in all, the Oakcastle MP100 is a portable Bluetooth MP3 player that supports wired and wireless listening. This tiny device is loaded with features to bring your favorite music wherever you are. It comes with brilliant design that makes it a perfect companion for sports and outdoor activities. Supported by rechargeable and long lasting battery, the MP100 is the best MP3 player you could ask for.
