We say :

Roland's R-07 is the latest in a long range of high quality, hand-held audio recorders. It offers a huge range of functionality for a musician and teacher. We like the range of recording options, the dual recording mode (which can rescue your recording when the levels might not be quite right), and the remote control bluetooth features which allow you to control the recorder from your smartphone or watch.

Roland say :

The R-07 packs mission-critical recording features into a stylish and ultra-portable device that goes anywhere life takes you. High-resolution audio, one-touch Scene memory, and Hybrid Limiting ensure great sounding recordings no matter what the situation. And wireless listening and remote control mean you can record with less wires in more places.
