I was in search of good vocal mic for my band?s female vocalist and came accidentally to Sennheiser products. In comparison with similar products like Shure SM58 or AKG D5 I came up with conclusion that this could be better mic of choice for that specific case. It brings more articulated highs and clarity which is really important for mezzo soprano and soprano vocals. It helps vocals be on top of band without interacting with guitars. it is very important for example in case of singing in metal or rock band.
Another terrific option is feedback reduction. I?ve never seen so good results with that with other mics. If you stand next to floor monitors, it makes complete silence and no feedback. Moreover even if you cupping microphone which not allowed in terms of physics it shows great result - no feedback is found. Used this microphone to record live and home without using headphones but room monitors at pretty loud volume. The result was awesome - low level of background band and qualitative recording of vocals.
Feedback and surround noise reduction is major point of this microphone in my opinion that makes E845 be one step ahead from other mics. It is worth noting that other products of this line (like E825 and E835) has same good feedback reduction and frequency response characteristics since they has same main capsule inside, as far as I understood it,, however they are a bit less present than E845. I think Sennheiser E845 is worth its money and is great alternative to Shure SM58 despite the fact that Shure has made a world standard dynamic microphone. Oh, and there is almost no proximity effect! GREAT mic!
