MP3 player SENCOR SFP4408BK with 8 GB internal memory, microSD slot, FM radio, voice recorder

The SENCOR SFP4408BK MP3 player is a compact portable audio device with 8 GB internal memory and a 1.1" LCD display. It supports MP3 and WMA playback, and accepts microSD cards up to 128 GB for expanded storage. The player includes an FM radio, WAV voice recorder, micro USB connection for charging and USB drive function (FAT32/exFAT), a belt clip and a key lock function. A built-in 3.7 V / 110 mAh battery provides up to 7 hours of playback at half volume. The package contains the MP3 player, earphones, USB cable and a user manual.

Advantages

The SENCOR SFP4408BK combines a small form factor (54 x 33 x 16 mm, 21 g) with expandable storage via microSD, allowing thousands of tracks to be carried when a card is added. Its dedicated playback format support (MP3, WMA) and straightforward 1.1" LCD interface make file navigation and listening simple. Integrated FM radio and WAV voice recording add utility beyond music playback, while USB drive mode enables easy file transfer and charging via micro USB. The inclusion of a belt clip and key lock improves portability and prevents accidental input during use.

Suitable for

• Listening to music during commuting, walking or exercise
• Students or professionals who need a simple audio player with voice recording
• Users who prefer a lightweight device separate from their smartphone
• Situations requiring offline radio reception or recorded voice memos

When it may not be suitable

The SENCOR SFP4408BK is not designed for high-resolution audio playback or streaming services; it supports MP3 and WMA formats only. Battery life is limited by its 110 mAh cell, providing up to 7 hours at 50% volume and shorter runtime at higher volume levels, so it may not meet long-haul travel needs without periodic recharging.

What to consider before purchase

Usage recommendations

For optimal battery life, keep volume around mid-level and disable unused features such as the backlight or radio when not needed. Use exFAT or FAT32 formatted microSD cards for best compatibility when expanding storage. Regularly back up recordings and music files by copying them to a computer via the micro USB connection.
