It works well. But
(1) don't get mislead by the product title (Olympus Telephone Recording Device). It is not a recording device but a Telephone Pick-Up Microphone.
(2) It is it can only be used with voice recorders or any computer which "power-supply" line-in input. It won't work by plugging into line-in of any iMac unless using an USB adapter.
