The microphone started cutting out after about a month and eventually got to the point where it simply didnt work. When I put it in the case the light would flash red four times them turn off, and it would repeat that every 30 seconds or so. Bought this windscreen for an MXL770 for home use and am overall pleased. Very convenient and I dont have to split my time between music and charging! Please replace with 4 . but did not get my money back. Some kind of picture showing how they should be arranged when putting them on would be helpful Ended up giving them to my daughter. Sound quality is top notch. I have a multitude of sizes and Im not willing to give them up.
