With the Olympus WS-852 you make clear sound recordings in every situation, from an intimate interview to a large meeting. The stereo microphone of this voice recorder has a low-cut filter that filters the noise from a recording. This allows you to clearly listen to every conversation. With a memory of 4 GB you can store 65 to 1040 hours of recordings. How much you can save depends on the sound quality set. Do you not have enough storage space? No worries. You can easily expand the memory with a microSD card of up to 32 GB. At the top of the voice recorder you will find an extendable USB connector. Plug it into the computer and transfer files without using a cable.
