I'm not sure what you may want to use them for but they do provide reasonable sound for not a lot of money. I have use of the 40/35 and 22 and use them for vocals, with the 40 also being used on guitar cabinets. They will not perform well for 2 point stereo, concert recordings. They simple do not have the frequency range, nor the refinement needed for concert recording. But if you are looking for a cheap, decent vocal mic, this might be the ticket. As a vocal mic they are much better than Shure 58's and I like them better than Audix OM7's. However, I like my Senn. 431, AKG 535, Shure 87, Neumann 105 and Shure KSM 9 better.......but they all cost more and for the right voice the 40 may even sound better.
