10 Best Mp 4 Players 2025 in the United States

The Sony NWWM1AM2 Walkman is designed for music lovers who want high-quality audio on the go. It supports high-resolution audio and native DSD files, making it great if you care about sound clarity and detail. The player comes with 128 GB of storage, which is decent for holding a large music library and suitable for most high-res files. Its 5-inch screen offers a clear viewing experience, though it may not be as sharp as some modern players with higher-resolution displays. Battery life is described as long, allowing many hours of playback without frequent charging.

The built-in S-Master HX digital amplifier helps keep the sound pure and rich. Connectivity includes Wi-Fi, allowing you to download or stream music directly, adding convenience beyond just playing stored files. Sony devices typically offer intuitive navigation, contributing to an easy user experience. Additional features include a sturdy aluminum frame, premium headphone jack options, and a three-year extended protection plan for peace of mind.

This Walkman excels in audio quality and durability. If you prioritize very large storage or a touchscreen with the highest resolution, you might want to compare with other players. It is a solid choice for users focused on premium music playback rather than multifunctional media consumption.

The FiiO M21 is a solid choice if you want a portable music player that handles lots of file types and offers excellent sound quality. It has a decent 64GB of storage, which is good for storing many songs, and its Android 13 system means you can run popular music apps smoothly. The 4.7-inch screen is neither too big nor too small, making it comfortable to navigate your music library.

One of its standout features is the advanced sound hardware — four DAC chips and a special amplifier design deliver clear, detailed audio, which audiophiles will appreciate. The player supports both standard 3.5mm and 4.4mm headphone outputs, plus SPDIF and USB audio output, giving you versatile options to connect to headphones or external sound systems. The device also supports Bluetooth and Wi-Fi, so you can enjoy wireless listening and app-based streaming. It’s a bit heavier than typical players, which may affect portability slightly.

If you want a user-friendly interface with strong audio performance and the flexibility of Android apps, the FiiO M21 is a good fit. However, if long battery life and ultra-lightweight design are your top priorities, you might want to look elsewhere.

The JadeAudio/FiiO JM21 is a stylish, lightweight MP4 player that runs on a custom Android 13 system, making it easy to use and allowing access to popular music streaming apps like Spotify and Apple Music. It comes with 32GB of built-in storage, which is decent for storing a good collection of music and videos, and also supports Micro SD cards if you need more space. The 4.7-inch touchscreen offers a clear and comfortable viewing experience, suitable for watching videos or navigating menus.

One of its standout features is the powerful Snapdragon 680 processor, which helps in smooth operation without draining the battery quickly. Speaking of battery life, it provides about 12.5 hours of playback, which is enough to last through a full day of music or video without needing a recharge. Sound quality is a strong point for this player thanks to its dual flagship DACs and audiophile-grade components that deliver rich, balanced audio; it can easily drive large headphones for a satisfying listening experience. Connectivity-wise, it supports Bluetooth and Wi-Fi, allowing wireless use and easy syncing.

The device requires a 9V battery, which might be less convenient compared to built-in rechargeable batteries found in many modern players. Also, the device's thickness is just 13mm and weight around 156 grams, making it very portable and comfortable to hold. This player is an excellent choice for music lovers who want high-quality sound, good app support, and solid all-day usage in a compact package, though those seeking extended battery life or integrated rechargeable power sources might want to consider this aspect.
