When our Sennheiser rep brought this capsule by I couldn't help think sarcastically , 'yea another capsule.'  I had not idea this was the new replacement to the 9235 which is now discontinued.  This capsule has an amazing frequency response for a dynamic capsule. Very much like the AKG D7 just in capsule form. The off axis to the cardioid pick up pattern is crazy tight. (that's a pro term).  If you are shopping capsules for your Sennheiser wireless this needs to be on your bucket list.
