State-of-the-art live sound featuring a choice of Sennheiser‘s renowned 835, 845, 865, 935, and 945 capsules on a lightweight aluminum transmitter with integrated mute switch.

The 835, 845 and 865 vocal microphone capsules are all great options and vary depending on your needs. While the 835 is ideal for most stages and features a cardioid polar pattern that rejects unwanted stage noise from the sides and rear, the 845 features a super-cardioid polar pattern that offers even more rejection and isolation for your vocal performance. The 865 introduces a condenser super-cardioid capsule, offering more sensitivity and clarity than a traditional dynamic capsule like the 835 or 845.
