80GB MP3 Player with Bluetooth and WiFi - Dedicated Music Player

In this review the SWOFY 80GB MP3 player M503 Pro is assessed as a dedicated music and audiobook device aimed at families and anyone who wants phone-free streaming. The bottom line: it is best for parents who want a durable, child-friendly media player with large local storage and WiFi streaming support. The single biggest reason to buy is the combination of expandable storage, preinstalled streaming apps and parental controls that let kids enjoy audiobooks and music without a smartphone.

Key Features

• 80GB storage: The player ships with 16GB internal plus a 64GB card so users can carry thousands of songs and audiobooks without touching a phone.
• WiFi and Bluetooth: Dual-band 2.4 and 5GHz WiFi and Bluetooth 4.2 enable stable streaming and wireless listening to headphones or speakers.
• Long battery life: The 2000mAh battery supports roughly 50 hours of music playback through wired earbuds, making it convenient for travel and long car rides.
• 4.0 in touchscreen: A 4 in IPS touch display that supports 720p and 1080p video gives a crisp interface for navigation and media viewing.
• Expandable and flexible: A microSD slot supports large storage growth and the device runs Android 9.0 so apps preinstalled for audiobooks and streaming can be used or removed.
• Parental controls: Parents can manage app installs and set a password to prevent unwanted apps, which helps create a safer kid-friendly device.

Who It's For

The SWOFY M503 Pro suits parents who want a dedicated media player for children that supports streaming services and audiobooks without giving a child full phone access. It also fits commuters and travelers who want long battery life, lots of local music capacity and offline playback for playlists and audiobooks.

Those who should look elsewhere include users who require full Google Play services or apps that depend on Google player services, and people who need the latest Bluetooth codecs for audiophile wireless listening since the device uses Bluetooth 4.2.
