>>1061943They are a little pricey for what they are which is shitty but it's asbolutely essential to have one, especially with these mics. You might also want a little tripod or something, because handling noise is an issue with these as well. Not critical to buy right away.
These are the 3 dead kittens I could find that fit the DR-05. I have a Windtech one and it works great, and it's the cheaper option.
