Sennheiser Pro Audio Sennheiser EW 100-CI1 Instrument Wireless System - G Band (566-608Mhz), 100 G4-CI1-G

This might be long but I want to write a good review. In a nutshell, this is the best wireless I Have ever used. Perfectly clear, range is excellent and I can use this for my bass or guitar. That said, these are the PROS and CONS:Pros:Excellent rangeExcellent ClarityEasy SetupDurableDisplay on transmitter and receiver is excellent. (Battery indicator is displayed on the rack)Cons:Rack mount bracket is a bit funkyThe included instrument cable is a joke (buy a backup)The BNC cables should be included and are not.The rack gets screwed together and it fits as expected. The design and layout of the rack is questionable but it works as expected. The transmitter cable is an absolute joke. Its a cheap flimsy cable and it was obvious when I set it up it was a matter of time before it malfunctioned. This is the spare I bought which is infinitely better:TISINO 1/8 to 1/4 Stereo Cable, 3.5mm to 1/4 Adapter Aux Cord Stereo Audio Cable for Guitar, Keyboard Piano, Laptop, Home Theater Devices, Speaker and Amplifiers -Nylon Braid 3ftThe BNC extenders should have been included for racking and for $600 they should have been. The ones that Sennheiser sells are outrageously expensive $40-$50 and you have to order them. I bought these and they work PERFECTLY:Eightwood BNC Bulkhead Female to BNC Male Right Angle Adapter RG58 Cable 50cm /1.6 feetI would highly recommend buying a spare transmitter cable and keep it handy. Although it doesn't screw to the transmitter like the Sennheiser, the quality is infinitely better and the screw down function isnt necessary.Overall, this unit is incredible! I hate noise when I play and I dont hear any introduced by this unit. Phenomenal!!!
