I'm also used in interviews and not disturb others, I had slipped into my pocket. The sound is only slightly degraded, which is not annoying. It is then possible to adjust the microphone sensitivity, or to choose between several modes denregistrements (maintenance, dictation text)
However, some features are not very clear and I can grope well before the master.
Battery life is very good, I have to be to 40 hours of use and yet I still have at least half of the battery. It would have been quite able to recharge by plugging it into a USB port on the computer.
Point greatly appreciated strong, the possibility of a memory expansion with a Micro SD slot. I've never personally served but japprécie nonetheless. The built-in memory can store 70 hours of classes / interviews.
Finally, I havent had any problems with it being detected by my computer when I plugged lai it.
A more detailed notice would have been nice.
In the end a very good product that responds very well to my needs and expectations.
