Andrew, this may not help but for what it is worth, I purchased the b3,which is like the b1 with switchable omni pattern and bass rolloff. I did not like the sound of my voice while monitoring with headphones while singing. I try to close mike to minimize ambient noises and the proximity effect was too wooly. I needed to eq to get a usable sound. i traded up to the c1 and get a good sound with no eq at all. I only kept the b3 for three days and only tried it on my own voice. For me, the upgrade was worth the difference,because the way I hear myself affects the performance. I actually liked the mike clip on the b-series,very clever once you get used to it. I also thought that the recorded sound was very nice when tweeked with eq,so I think the b-series is well worth the money, but then the c-series is only a little more so for me it was the way to go. I was lucky to purchase from a dealer that allowed the exchange and that is by far the best way to find what works best for you. Good luck
