The Super-Shield, Small will fit both the Sennheiser MKH8060 & the Audio-Technica BP4025. There are just two points I'd should mention. Firstly the cable supplied with the Super-Shield is a 3-pin XLR, so that'll need swapping out for the 4025 & the cable replacing it needs to be skinny, as the cable exit point will only accept up to 5mm cables.
Secondly, as the BP4025 is larger diameter than the Sennheiser (19mm), you may want to go for a spare pair of Lyres, so you have a set for each mic. The Lyre will recover, but not quickly if you're in a rush. The replacement lyres code is below:
