Sennheiser ups the ante on their EW 100 line with the G4-945-S. This set shares the same features as the EW100 G4-835-S. The main difference is the capsule.

In contrast to the 835 capsule, the 945 capsule has a more neutral sound with a gentler high frequency. This makes it ideal for larger venues as high frequencies tend to be more susceptible to feedback in larger venues.

The supercardioid pattern also helps in feedback resistance, offering a tighter pickup pattern with better side rejection than the cardioid 35 capsule.

The Sennheiser EW100 G4-945-S presents a great alternative to the cardioid 835 series. If you want more feedback rejection or a more neutral sound (or both), the 945 is better suited for you versus the 845.
