I don't use this windscreen with the Olympus LSP2, but with my Olympus LSP4 recorder, which has the exact same dimensions as the LSP2. It's a pretty good windscreen for this recorder. It provides protection against wind noise in light to moderate winds. And it does so without muffling the sound very noticeably. Moreover, it's a snug fit that will stay on the recorder even when moving a lot. The windscreen does block the access to the headphone jack of the Olympus somewhat, but I found it is perfectly useable when you first plug in the headphone and then put on the windscreen. The windscreen itself is not too big either and fits perfectly together in a small pouch I got for my recorder (a pencil case)
Indispensable when you want to record outside with your small Olympus.
