Sony ICD-SX2000 High-Resolution Digital Voice Recorder has 16GB of internal memory and can capture up to 636 hours of MP3 recordings. Additional storage can be provided via its microSD memory slot and optional memory cards. With the REC remote app, the device can be controlled wirelessly from your Android or iOS device over Bluetooth.
The recorder sports two adjustable microphones, allowing you to capture stereo recordings in a variety of placements. Three settings include Zoom (for situations including business meetings), XY (for things like band rehearsals), and Wide Stereo (for recording outdoors). You can adjust the sensitivity of the microphones in a variety of different ways, and set the device to record only when it hears noise above a certain level allowing the recorder to be voice-activated.
