If you want to do something with an average budget, these guys are perfect. They are factory matched, not compared with tests like KM184s and other high-end instrument mics. For mine, there are a small difference around 3k (with cardioid capsules) which can be compansated easily with an EQ but these capsules (omni ones) are like same with each other.
I have compared them with DPA's. DPA's a bit softer in a good way and of course have almost no signal-to-noise. SE's have a tiny background noise with them but considering them with a quarter of price (maybe less) makine these guys are a good friend.
I use them with classical recordings plugged into Focusrite 18i20's and they just work fine. No complainments are received.
