10 Best Mp 4 Players 2026 in the United States

The FiiO M21 is a solid choice for anyone looking for a high-quality portable music player with plenty of storage and good sound performance. It comes with 64GB of built-in storage, which is enough for a large music collection, and runs on Android 13 with a Qualcomm Snapdragon 680 processor for smooth operation. The 4.7-inch screen offers a decent size for navigation and viewing song info, though it’s not the highest resolution compared to some competitors.

One of the standout features is its advanced audio hardware, including four CS43198 DAC chips and a two-stage headphone amplifier, delivering clear, detailed sound with strong dynamic range—great for audiophiles or anyone who cares about sound quality. It supports a wide range of file formats, including Hi-Res Audio and DSD, and includes versatile output options like dual headphone jacks and SPDIF for connecting to other devices. Battery-wise, it has a unique Desktop Mode that helps extend battery life when plugged in but does require a 9V battery included with the device.

The user interface benefits from Android 13, meaning you can use popular music apps easily, though the learning curve might be slightly higher than simpler MP3 players due to its advanced features. The FiiO M21 is well suited for music lovers who want excellent sound quality, solid storage, and flexible connectivity, but casual users looking for ultra-long battery life or a simpler interface might find it a bit complex.

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 HiBy R4 is designed for those who want a high-quality MP3 and MP4 player with plenty of storage and strong audio performance. It comes with 32GB of built-in memory but stands out by allowing you to add up to 2TB more via a microSD card, so you can carry a massive music and video collection. The screen is a 4.7-inch LCD with good resolution, making it comfortable for watching videos or browsing your playlists. Battery life is solid thanks to a 4500mAh battery, which should support many hours of continuous listening or viewing before needing a recharge. This player runs on Android 12, so it’s easy to use and lets you install popular streaming apps like Spotify, Amazon Music, and YouTube, offering great flexibility beyond just stored files.

One of its strongest points is audio quality. It boasts advanced sound technology including multiple DAC chips and a Class A headphone amplifier, which means music sounds clear, dynamic, and detailed, suitable for audiophiles or anyone who really values sound quality. It supports a wide range of audio formats, including high-resolution files and Bluetooth codecs, which helps keep the music sounding great whether wired or wireless. The player also offers both 3.5mm and 4.4mm headphone outputs, accommodating different headphones for better sound.

Controls are straightforward with physical function keys for easy access to common tasks, which is convenient when you don’t want to rely solely on the touchscreen. The device’s dual-band WiFi and Bluetooth 5.0 capabilities make wireless connectivity reliable and fast. On the downside, the screen size is moderate, so if watching lots of videos on a large, high-res display is your priority, this might not fully satisfy you. Also, while the device is powerful, the learning curve for Android and multiple features might feel a bit much for users wanting a simple, basic player. Finally, the unit's price might be higher than more basic MP4 players due to its premium sound components and smart features. The HiBy R4 is a great choice if you want a versatile player that combines high-res audio quality, expandable storage, and streaming capabilities in one device. It's especially suited for music lovers who want excellent sound and some smart features without carrying a phone everywhere.
