This is the portable cassette player that preserves classic tapes by converting the songs into MP3s. It faithfully transfers a cassette to a digital audio file and lets you pause mid-recording to skip or select certain songs, turn the tape over, or swap out the cassette to make compilation recordings. The converted MP3s are automatically transferred onto a USB flash drive (required). Unlike bulky models that require a computer, this unit is as compact as a tablet and converts audio without any complicated programming or software installation. It has a 3.5mm headphone jack, built-in microphone for custom recording, and a speaker. Powered by included AC adapter or four C batteries (required).
