Ok since you really want to know ...
I think these mic's are not the greatest ( to say the least ). When I started taping many years ago I started with the Sony ECM mic's . At the time ( and I am talking the 80's ) there was no internet , no way to get info so I thought that was all that was available at the time ( where else than the regular store could I go for mic's ? ) . I din't have the same model but something sort alike of what you have now .
Nowadays there is so much info available that there is no need to get a mic like the ECM's . Anytime I hear a recording made with these mic's I feel sorry since I think there is so much better available today , and sometimes for not even that much more .
I think they are sounding very very flat , no bass at all . They have a terrible thin sound .
Brands like Microphone Madness , SP , Core -Sound make great sounding mic's for under $ 250 ( and I heard great sounding MM"s for not even $ 175 !) .
If I were you I would sell them again at Ebay and get something better , if you are serious about taping ( you did find this page so you are probably serious !) .
Think about this...you can only make a good recording once !!! Why not have a good mic to do the job
Good luck !
