It features a compact design with dimensions of 78.9 x 72.0 x 19.5 mm and weighs approximately 137 grams with the battery installed.

The device supports a sampling frequency of 44.1 kHz, with the ability to convert 32 kHz and 48 kHz recordings to 44.1 kHz. Designed for convenience, it includes a rechargeable nickel-metal hydride battery which enables around 6.5 hours of recording or 12 hours of playback on a single charge. Using an additional external AA battery or the battery case, it can extend recording time to approximately 15.5 hours and playback to 30 hours. The device offers a 3.5mm line input and microphone input, as well as a 3.5mm headphone output.
