10 Best Mp 4 Players 2025 in the United States

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 JadeAudio/FiiO JM21 stands out as a high-performance MP4 player, boasting a powerful Snapdragon 680 processor and a customized Android 13 system. This means it runs smoothly and lets you install popular streaming apps like Spotify or Apple Music, which is great if you want more than just local music playback. Its 4.7-inch touchscreen is a convenient size for easy navigation without feeling bulky. Storage comes with 32GB, which is decent for many songs but might feel limited if you have a large music library; however, the Android system may allow for expandable storage options via apps.

Battery life is solid at around 12.5 hours, enough for a full day of listening without frequent recharging. Sound quality is a key strength here, thanks to dual flagship DACs and a powerful 700mW output, enabling it to drive even demanding over-ear headphones with clear, detailed audio. This player’s balanced audio setup and advanced digital purification system ensure you get lossless, high-resolution sound whether playing local files or streaming. In terms of controls, the touch interface combined with Android’s openness offers a user-friendly experience, although some users who prefer simple, dedicated music players might find the Android system a bit more complex initially. Connectivity options like Bluetooth and Wi-Fi add versatility for wireless listening or streaming.

The 32GB storage might require managing files carefully or relying on streaming to avoid running out of space. Also, while the device is lightweight and slim for comfort, it may not appeal to those looking for the simplest MP3 player without smart features. This makes the JadeAudio/FiiO JM21 a compelling choice for music lovers who want high-quality sound, smart features, and good battery life in a portable player, especially if you appreciate flexibility with apps and streaming alongside local playback.

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.
