10 Best Mp 4 Players 2025 in the United States

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 Innioasis 160GB MP3 Player offers a robust set of features suitable for both kids and adults who want a dedicated music and media device without needing a phone. Its standout strength is the massive 160GB storage capacity, which includes a 128GB SD card and the option to expand further up to 1TB. This allows ample space for music, videos, and other media files. The 4-inch HD touch screen provides a good viewing experience for videos and easy navigation through the user-friendly interface.

The device supports a wide range of audio formats, ensuring compatibility with most music files. Additionally, it comes pre-installed with popular music and audiobook apps like Spotify, Pandora, and Audible, making it versatile for streaming and offline listening. A significant benefit is the inclusion of parental controls, allowing parents to manage app installations and ensure a kid-friendly environment. The dual-band WiFi and Bluetooth 4.2 enhance connectivity options, making it easy to pair with headphones or speakers.

However, the device does have some limitations. The 1500mAh battery, though decent, offers up to 25 hours of music playback or 5 hours of video, which may require frequent charging for heavy users. Additionally, it cannot install apps that require Google Play services, limiting some app availability. Despite these drawbacks, the Innioasis MP3 player is a solid choice for those seeking a dedicated media player with extensive storage and kid-friendly features.

The FiiO M23 is a solid choice for those seeking a high-quality portable audio player aimed at audiophiles or anyone serious about sound clarity. It features 64GB of storage, sufficient for thousands of songs, and a 5.5-inch screen that supports a clear resolution, enabling comfortable navigation and easy use of music apps. Running on Android 10, it allows installation of popular streaming services like Apple Music or Tidal, so users can enjoy lossless streaming without needing an additional device.

This player distinguishes itself with advanced audio hardware, including a top-notch DAC setup that delivers natural and well-balanced sound. Special modes such as desktop mode extend battery life and enhance audio quality when using larger headphones. The M23 supports numerous audio formats, including lossless options like DSD and MQA, offering flexibility in music file compatibility. Connectivity options include Bluetooth, Wi-Fi, and USB DAC capabilities, providing multiple ways to connect to other devices or speakers.

Battery life, while improved in desktop mode, may not satisfy users expecting extended use away from power sources. Weighing about 1.46 pounds, it is heavier than more basic MP3 players and might feel less pocket-friendly. Controls follow standard Android conventions, which are familiar to many but could be less intuitive for those preferring simpler dedicated buttons. The FiiO M23 is ideal for users who prioritize high-resolution audio, modern streaming, and customization options over ultra-portability or the longest battery life.
