Very Good--perhaps not as Outstanding as I had Hoped
I have owned and utilized the EW 300 IEM Transmitter/Receiver combination for several months now. I gladly purchased it from Sweetwater. Before I comment upon the system, I would add that 1) this is the first IEM transmitter/receiver I have used or owned; and 2) I utilize Jerry Harvey Audio IEMs with the Sennheiser EW300 System. Based upon the reviews I read, I expected I would have flawless reception from the components. While this is true 95% of the time, my use of the system in a church sanctuary that seats approximately 400 - 500 persons is not without "dropouts." These "dropouts" are temporally short -- lasting one second or so at the most -- but they do happen. The reason? FM transmission, overall, demands an "in sight, straight line" transmission path. If your transmitter/receiver pair find a wall -- or a sanctuary pillar -- between them, the odds increase that you will have a dropout. If the "line" between the transmitter and receive antennas is straight-on, you likely will not encounter any dropouts. As it is, church sanctuaries are inherently not constructed to be "sonically friendly," and certainly not ideal for today's digital technologies. (At least this applies to mainline Protestant churches, the type I have served.)
Beyond this small caveat, the Sennheiser EW300 system has been fantastic! Yes, there is a small amount of FM transmission "hiss"; that is normal. Yes, you can, if you have sharp ears, tell that the frequency response of this system peaks out around 15kHz and not 20kHz. But, the stereo image and separation is great; the gain available in one's IEMs is more than anyone would need, and the options available with this transmitter/receiver pair are obviously superior. I am thinking here of digitally adjustable levels, HF emphasis, EQ availability, and very fine sound quality.
Like me--a highly trained, professional musician--your ears will notice that this system is not perfect--certainly not as "perfect" as the average review will exhibit. However, for the price, this is a fine value. German designed and American built. Sennheiser -- German -- quality. And overall very, very fine sound. Unless you absolutely need the "next step up" in Sennheiser products and the accompanying high fidelity and additional options, I can only imagine this system will serve you very, very well, and provide 95% of what any of us are looking for in an IEM system. Especially if you put outstanding in-ear-monitors like JH Audio monitors in your ears, I believe you will be very satisfied. As I am. Thank you Sweetwater. And thank you Sennheiser for a fine product at a respectable price. That adds up to a very good value.

P.S. Digital units such as this are now beginning to be commercially available, and no doubt those systems will have sonic and pragmatic possibilities that will make these "more analog" units obsolete. But at this time, from my research, this is a high quality system of high value. And in this age of perpetual change, that is, in my opinion, saying a LOT! I would recommend this system to most anyone from beginner to semi-pro and even professional performer.
