I bought this to use with the Olympus DS series recorders, but it should work with most recorders that have inputs. It does come with adapters for mono, stereo, and mini-jack, and, of course you can buy additional adapters...
The phone recording works fine. Have confidence that it's working and remember to keep your own voice low to keep more of a balance in the recording. Sometimes, too, the playback on the computer turns out to be more balanced and better sounding than the sound on the device's own speaker.
And, as a bonus, you may want to use this mic for interviews rather than the tie-clip mic or the RS29. With the TP7 in your ear, it records people speaking next to you, or, across from you, very well.
Bottom line, if I only bought one accessory for recording with a DS recorder, this might be my first and only pick.
If it had a "pause" feature, I'd bump my review from four stars to six....
