After the many words of praise for this device and the technically same little brother, I have decided, despite the relatively high price to buy the LS-11. Purpose were music or voice. First, it was noted that the operation of the two control wheels is extremely "fiddly", thus requires a lot of tact; there is not a direct feedback, the color-neutral numerical scale is indecipherable for me without a magnifying glass. The possibilities of LS-11 are very impressive. The results - as a wave or mp3 - but rather not. Compared with recordings on an audio app of my Samsung smartphone that of Olympus fall back significantly. I have returned the device.
