I have a Sony hand held recorder (DCM-10, from memeory) and have been using some cheap microphones up to now. As the last one broke, I decided to get a decent mike and as the recommded one is no lonnger made and I couldn't find it cheap anyway, even on EBAY, I decided to try this one, which is it's replacement (Cheaper version)
The microphone is incredible. It picks up sound really well and I have to turn the input volume right down on the recorder. The stereo is also really good and you can really hear where voices are coming from.
There is an option to record in mono also.
The quality is great, just what you expect from Sony and I'm sorry I didn't invest in this or it's predecessor sooner.
The microphone comes with a table stand and the lead is equipped with a standard 3.5mm stereo jack. It takes 1 AA battery to power it and this seems to last a long time.
Build quality is maybe on the cheap side, Plastic housing, which may not be as durable as the original metal one. Also, it means that it picks up far more hand noise so you really have to not move your fingers at all if using it that way or it will totally spoil the recording. Best option is to hold it using the stand (but still be very careful as it will pick up any slight movement of fingers on that too) or better still on a boom, if you can't put it on a table/other surface.
Other than the plastic cover, can't recommend this highly enough.
