10 Best Mp 4 Players 2025 in the United States

The FiiO M17 Portable Desktop-Class Music Player is a high-end device designed for audiophiles who demand top-notch audio quality. Key strengths include its superior DAC and amplification technology, which ensures excellent sound clarity and minimal distortion. The device also features robust connectivity options, including multiple headphone and line-out outputs, USB ports, and Bluetooth 5.0, making it versatile for various audio setups.

The large 5.99-inch screen provides a good display size for navigation, and it runs on Android 10 OS, allowing the installation of third-party apps for a more personalized experience. The battery life is quite impressive, with a massive 9200mAh battery offering up to 10 hours of playback time, although the charging time is relatively long at 4.5 hours. The M17 also boasts a unique RGB ambient light system for added visual appeal and a cooling system to manage heat dissipation during extended use.

However, there are some drawbacks. The device is quite hefty, which might make it less portable for on-the-go use. Additionally, the internal storage capacity is only 4GB, which is quite limited, though it does support external micro SD cards for expanded storage. The price point may also be a consideration, as the advanced features and high-quality components make it a premium product. The FiiO M17 is best suited for serious music enthusiasts looking for desktop-level audio performance in a portable format, but it may be overkill for casual listeners or those seeking a more compact and lightweight player.

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.

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.
