Portable audio with 128 GB storage

The SWOFY M4 is a portable MP3 player that comes with 128 GB of internal memory and a 2.4 inch LCD touchscreen. It supports Bluetooth 5.4 for wireless headphones and includes a built-in speaker, FM radio, voice recorder and e-book reader. The device uses a lithium-polymer battery and charges via USB Type-C.

Replaces a phone for focused listening

This player suits anyone who wants music, radio or audiobooks without the distractions of a smartphone. It adds local storage and a dedicated interface so you can leave a handset at home during workouts, commutes or study sessions. The jump is worth it when you prefer physical controls and long battery life over streaming apps.

Simple setup with included accessories

Connect the supplied Type-C cable to a computer to drag and drop files; the player appears as a USB drive. Pair Bluetooth headphones through the on-screen menu or plug in the wired earbuds provided. The touchscreen handles all functions, though users unfamiliar with gesture navigation may need a short learning period.

Questions about this item

What are the exact dimensions of the SWOFY M4 so I can check if it fits my pocket or armband?

The player measures 5.87 by 5.75 by 0.74 inches and weighs 5.6 ounces, making it compact enough for most pockets or small armbands.

How do I load music onto the 128 GB internal storage, and what is the common mistake to avoid?

Connect the supplied Type‑C cable to a computer; the device appears as a USB drive. The frequent error is unplugging before the file transfer finishes, which can corrupt the music library.

When will the built‑in lithium‑polymer battery need replacing, and how is it done?

The sealed battery is not user‑replaceable; after several hundred charge cycles runtime will shorten, at which point the unit must be sent for professional service.
