Crystal Mic Pro F (The Fulcrum)
The PRO F version is our latest design featuring a vertical swivelling (hence the name Fulcrum) microphone boom with the following microphone options:
i) David Clark M7A TSO microphone
ii) BoseA20 TSO microphone (the same one used on Bose A20)
iii) Gentex low impedance microphone (used on military Bose A20 models)
iv) Crystal Mic M7A2 microphone (similar specification to the David Clark M7A TSO)
Buy the Fulcrum if you want a headset similar to the Bose A20 with a mic boom that swivels in the vertical plane.
Default choice is the left side mic. If you want the right side mic, please specify in the notes section on check out.
The microphone boom is firmly held in place using an E-clip. The microphone assembly will not come out of the headphone socket easily if you tug on the cables unlike products made by our competitors.
Available for the Sony WH-1000XM3 / XM4, Bose QC35 and Bose 700 models.
If you choose the David Clark M7A or BoseA20 microphone, only the microphone is TSO and not the entire headphone / Crystal Mic combination. We cannot TSO a third party headphone that is not manufactured by us.
