A pleasant surprise that this purchase I wanted above all useful for recording meetings dense information. The sound quality is very good, allowing comfortable listening. Nevertheless, I recommend buying a foam cover for protection, but also to isolate noise from the table. For the rest it is used like a USB stick: easy to load, easy to transfer recordings. Very comfortable autonomy. The leaflet, beyond the basic functions, is not very explicit, and you have to download the instructions on the manufacturer website. The downside to the supplied headphones, not too comfortable.
