[95%] You can trick the eyes but you can't trick the ears.....ALWAYS remember that Weddings. I could write a book about all the things that can go wrong at weddings for a videographer and poor audio is on top of the list. With weddings, you get one chance and one opportunity, in most cases, so I am most impressed with the simplicity of setting up the AVX, as well as the crisp and clear sound quality it produces. Pairing is as easy as pushing a button. There is no second guessing about signal strength or fine tuning, as it does it all for you, and it sounds great. (Quick story)....Groom comes out, bride comes down isle, preacher gets ready to talk and turns on his microphone. Yes, you guessed it. Mr groom is linked to the preachers microphone and is back-feeding to the amplified sound system. I then became part of the ceremony when I had go to the groom to correct this. GEEEZ! This will not happen with the AVX system as it uses a different frequency range not common to other wireless systems. However, if there is one, it will change automatically to an available frequency for you and continue to do so. Very impressive indeed. Don't think for a minute that simplicity doesn't have its price, it does, but the AVX is well worth every penny and here is why. There's no white noise jumps, crackles, or audio level changes. This can take hours to correct in post production, and even then only making it sound a little better. You seasoned videographers know exactly what I'm talking about. I feel better turning over a final product to my customers knowing the audio will definitely not be an issue what so ever.

[Maximum 120 mA] This combo set is a perfect fit for location shooting and run & gun audio recording. Matches up perfectly with my Sound Devices and Zoom recorders and I don't need to lug around the larger receiver boxes that my other wireless mics come with. It has all the features I need, the sync and setup takes seconds and it takes very little space in my go-bag.

[95% maximum] I use this kit primarily for educational videos where one or two people are talking in a controlled environment. I find it very intuitive to use, and have yet to have any signal issues. The encrypted digital signal prevents cross-talk like you might get with the G3. This particular kit does not come with backup batteries, although the case does come with slots for 2 receiver backup batteries, and slots for 2 transmitter backup batteries. There is no extra slot for the stick microphone backup battery, but it can fit diagonally in the square compartment. I highly recommend getting backup batteries if you plan to shoot two people for over 3 hours since the small receiver batteries only last about 4 hours, although if you have a digital recorder with phantom power on the XLR input where the receiver is plugged in, the receiver will automatically turn off if you turn off the recorder. This helps conserve battery. The transmitter packs are small relative to the Rode system which is partly what sold me on this system, and this kit option was hard to beat.

[50 or 60 Hz] This is the best thing since apple pie! I use a lot of different cameras mounted in a lot of different ways and the Sennheiser wireless mic combo gives me not only the right amount of flexibility, but is so compact and easy to work with and around that I don't even notice it's there. No problems with frequency location, bleed in or conflict issues (I use two of them at a time, side-by-side) on most shoots. I have the lav and mic setups and can go to my field audio recorders, directly into the camera or into the field recorder and then into the camera or mixing board if I need to, the system works perfectly for me. I initially bought one set and was so impressed I turned around and bout the second.

[BA 40] This little thing is the most portable and reliable on the go mic system I've seen and tested. Works awesomely. Audio quality is superb

[OLED] I love my Sennheiser AVX lavalier mics - I already had two - and then bought this kit. It's a beautifully rugged and compact carry case for my entire system. It makes it easier now to keep everything together and be ready to go.

[50 or 60 Hz] My 2nd set. I really love this lev set.

[OLED] This product is easy to use and produces crisp sound. Love it!

[> 90 dB] I am very happy to buy this mic, work amazing!

[50 Hz to 20 kHz] I have used this system for a few months now and it has held up very well. Like others I have switched from a G3 system to this because of some interference issues but I have had no real interference issues with this system yet. HOWEVER, I have had some odd noise/interference when I have had my Tram TR50 mic near the transmitter (within a foot or so) I thought that this was outside interference at first but it is the microphone itself picking up some transmission noise (happens only with my Trams so I'm assuming that the shielding is not as good?). This may explain the two poor reviews describing interference that was constant? This has happened to me when I have the transmitter placed in the jacket pocket of the person being interviewed. Put the transmitter on a belt and it goes away. Build quality is better than G3 and I like the new batteries. I have used these on interviews now in downtown New York City, DC, St. Louis in places where I would get intermittent hits in the past but these have performed well. Small latency in the audio, but this is not noticeable in reality
