In the live performance of "When We Were Young" at The Church Studios, Adele uses the Sennheiser SKM 9000, Sennheiser's flagship wireless microphone. Previously, during her "21" album tour, she used the Sennheiser SKM 2000 handheld transmitter. While the specific microphone capsule Adele uses in this performance isn't identified, it is unlikely to be a Neumann capsule. Her backup singers appear to use the Sennheiser 5000 series, possibly the 5200, with entry-level capsules.

The article linked from Sennheiser details how Pitbull's team adopted and utilized Sennheiser's Digital 9000 system in live performances. The article quotes, "The rock-solid connection between the SKM 9000 transmitter and EM 9046 receiver has given Holden and Madera the ultimate confidence that great audio will continue running through their system no matter where Pitbull’s high-octane performances may take him."

On this photo you can see Miley using the Sennheiser SKM 9000 on her Bangerz tour. In an interview with Hummingbird Media, monitor engineer Vish Wadi says:

“Miley had been using an SKM 5200 handheld transmitter with a 5235 capsule which was a great combination for her – very robust and sounded good — but Paul [Hager] and I were really keen to try out the digital system. When we did, we both fell in love with the sound quality and the innovative RF capabilities, so we decided to move Miley over to the Digital 9000 system for this tour. She is using an SKM 9000 handheld transmitter with the MD 9235 capsule, and it sounds fantastic!”
