With summer outdoor taping opportunities approaching I picked up a pair of the Movo WST50s for my AKG active setup. I like the fit and construction especially for the price.
http://www.amazon.com/Movo-Professional-Windscreen-Technology-Microphones/dp/B00YHTUCQMI have one concern now that I have them on the mics. My AKG CK1X capsules are the kind with the cone shape back end that contains the LEMO jack. If I pull the screen up onto the mic so that the rubber base seals up against the sides of the capsules this only leaves a 1-2 cm space between the back of the vents and the surface of the rubber base. It also leaves a bit of an air gap at the front of the mic which could only be good. My fear is that the 4 inch round rubber base being so close to the vents would create reflections.
Only way to find out is to get out and use them so I'll report back later. I guess anything is better than getting wind noise ruining a recording.
In the past I've used the little stock AKG screens indoors just to have some just-in-case type protection. I've used DPAs indoors and in light gusts with success. Fail on gustier occasions. The Shure 81s never let me down but once they blew off some AK43s in a strong breeze. Since my current active caps are even smaller in diameter than the AKs I wanted some other solution, maybe something more compact as well.
