【Product Description】 SONY PCM-A10 FLAC: FLAC compatible HI−RES AUD.REC: High−Res Record MP3 recording compatible PCM recording compatible PC connection method: USB connection color: BLACK Stereo/Mono: Stereo Display type: MSTN Built-in memory type: Semiconductor Compressed music playback function: WMA/MP3 Recording media (new): microSDXC This IC recorder is suitable for recording human voices (e.g., meetings) and music. It's small yet high-quality, and I found it very useful. Bluetooth compatible, movable microphone. The "Track Mark" function, which allows you to mark points for easy review, and the "A-B Repeat" function, which allows you to repeatedly listen to specific sections, are convenient. I used this a few times after purchase. It's in good condition, but it's a used item, so please refrain from purchasing if you are sensitive to such things. No claims or returns accepted.
