10 Best Mp 4 Players 2026 in the United States

The FiiO M21 is a portable music player designed to deliver high-quality sound for music lovers who value detailed audio. It features a powerful Snapdragon 680 processor and runs Android 13, which means it can smoothly run popular music apps and manage your songs easily. With 64GB of storage, you have plenty of space for a large music collection. The 4.7-inch IPS screen offers decent clarity, but it’s on the smaller side compared to some other mp4 players, which might be less ideal if you want to watch videos often. A standout feature is its advanced sound system, including four CS43198 DAC chips and a two-stage amplifier that provide clear, rich, and dynamic audio, meeting the needs of audiophiles. It also supports many file formats, including high-resolution and DSD audio, ensuring you can enjoy a wide range of music types.

The battery setup is a bit unusual as it uses a 9V battery included in the package, but the Desktop Mode helps protect battery life by using external power when plugged in, which is a nice touch for longer listening sessions. Connectivity options like Bluetooth and Wi-Fi allow wireless streaming, and dual headphone outputs with separate amplification circuits let you connect different headphones easily. However, since it uses an LCD screen rather than OLED, the display might not be as vibrant, and the battery life could vary depending on usage since it’s powered by a replaceable battery rather than a built-in rechargeable one. The FiiO M21 is an excellent option for those who prioritize sound quality and flexible connectivity in a compact player, though screen size and battery rechargeability should be considered.

The HiBy R4 is a versatile MP3 and MP4 player designed for those seeking excellent sound quality combined with smart features. It offers 32GB of internal storage and supports expansion up to 2TB via microSD, allowing users to carry an extensive music and video library. Featuring a 4.7-inch high-definition screen, it is suitable for watching videos and navigating apps, though the screen size may feel small compared to larger smartphones or tablets.

Running on Android 12, the HiBy R4 provides a familiar interface and the ability to install apps like Spotify and YouTube, making it more than just a music player. Physical buttons offer quick access controls that are convenient for on-the-go use. The 4500mAh battery ensures many hours of playback before needing a recharge. Audio performance is a standout feature, with advanced components delivering clear, detailed, and distortion-free sound. It supports high-resolution audio formats including DSD and MQA. Wireless connectivity is seamless with Bluetooth 5.0 and dual-band WiFi, supporting high-quality codecs and streaming.

While the device offers a premium and unique design, the 4.7-inch display may not meet the expectations of users wanting a larger screen for video content. Additionally, the multiple connectivity options and advanced audio settings may require some learning for users less familiar with Android or complex audio devices. This player is ideal for music enthusiasts prioritizing high-fidelity audio and smart capabilities, though casual users who prefer simplicity might find it somewhat advanced.

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.
