10 Best Mp3 Players 2025 in the United States

This MP3 player designed for kids and teenagers stands out with its strong focus on parental controls, allowing parents to block or approve apps and set auto on/off times, which is great for managing screen and playtime. It comes preloaded with popular apps like Spotify Kids, Amazon Music, and Audible, supporting a wide variety of music formats, which means kids can enjoy many types of audio content. The device runs on Android 9.0, offering a smooth and familiar interface, although some users might find it slightly complex for younger children at first.

Storage is flexible, with 16GB built-in and the option to expand up to 512GB via a memory card, so it can hold a large collection of songs and audiobooks. Battery life is impressive, offering up to 50 hours of playback on a single 2-hour charge, which makes it very convenient for long trips or daily use without worrying about frequent charging.

The 4-inch screen is a good size for kids, and the player is lightweight and portable, making it easy to carry around. Connectivity is strong with Bluetooth 5.0 and WiFi, allowing seamless pairing with headphones, speakers, and car systems. Audio quality supports many formats, though as a kid-focused device, it’s decent rather than audiophile-level. Users should be mindful to remember passwords and PINs carefully to avoid lockouts, which could be frustrating. While updating or adding apps may require contacting the manufacturer, this device provides a safe, versatile music experience with parental oversight and good battery life, though it may require some initial setup effort and parental involvement.

The FiiO M21 is a solid choice for anyone looking for a high-quality portable music player. It comes with a good amount of storage at 64GB, which should hold thousands of songs, and runs on the latest Android 13 system, making it easy to use and compatible with popular music apps. Its battery management is smart, especially with a Desktop Mode that protects battery life during extended use.

The standout feature is its exceptional audio quality, thanks to four advanced DAC chips and a two-stage amplifier that provide clear, detailed sound with minimal noise. This makes it an excellent option for audiophiles or those who want premium sound on the go. In terms of portability, the M21 is reasonably sized and lightweight, making it convenient to carry around. The player includes various output options like dual headphone jacks and supports high-quality connections such as Bluetooth LDAC, SPDIF, and USB Audio.

It requires a 9V battery, which might be less convenient than built-in rechargeable batteries found in other models. Despite offering a good range of features, it is less popular compared to top-selling MP3 players, possibly due to its higher price or niche focus on audiophiles. If you prioritize sound quality and flexible connectivity over extreme portability or budget options, the FiiO M21 is a strong candidate.
