Mic: Well-built and the sound that it captures is, according to me, above-average quality for sure. Whether its a voice-over, a sung vocal line or an acoustic instrument (tried a six string acoustic guitar), it does a bang-up job. The clip that comes with it is also solid, although you should get a shock-mount. I opted for the tbone SSM2, and the mic fits nice and snug.
Headphones: This was the one that really did it for me. The sound is quite good! I was pleasantly surprised with what I heard. There is barely any leakage, even when listening at loud levels, which is so critical. Small area of improvement; I wish that the ear cavity was slightly larger to accommodate the ears...properly.
All the materials and components that go into the making of this bundle seem to be of medium to high quality and should last a long time, as long as you don't drop it or something. And again, since I am new at recording, I am not sure if I can say anything about the all the different software that comes with it, but it seems like it should be more than enough to address basic to intermediary recording needs for sure. Very satisfied with this bundle.
