Sennheiser ew335G2 E835 Cardioid HH Wireless System
If you're using several wireless mic systems on the same stage, the EW 335 system is definitely what you need. Every frequency you use cancels out lots of frequencies up and down the spectrum, so your choices narrow quickly. This system solves the problem with 1440 switchable frequencies and the ability to automatically scan all nine banks to find open banks with compatible frequencies. The green backlighted LCD on the EM 300 G2 receiver glows red when there's no signal from the transmitter.

You get peerless dropout-free signal reliability with complete freedom of movement at up to 150 feet. Based around the EM 300 rackmount receiver with 2 removable telescopic antennae, the system features the SKM 335 G2 handheld transmitter with dynamic, cardioid microphone head, which delivers amazing vocal clarity and presence and provides all critical info on its LCD. System strengths include: 8 banks of 8 compatible preset channels, one bank of 8 user-selectable channels, current channel bank displays, increased bandwidth, channel and bank indicators, frequency indicators, 4-step battery status display, lock mode with indicator, pilot signal reception with indicator, mute with indicator, 7-step level display for received audio signal, 7-step level display for received RF signal, plus XLR and 1/4" outputs on receiver.
