UPDATE 7/17/18 - I am happy to change my original 2-star review to 5 stars! The first mic I got had a terrible high-end screech, and as I dialed down to the correct volume, a high-pitched digital "hiss." I played with it and could get it to reduce, but not go away. This is on a Sony RX10 Mark 4. I sent the mic back, rather than wait for an exchange, due to a deadline. To Fifine's great credit, they followed up with me. Even though I had returned the unit, they asked if I would like another one to test. Their customer service was excellent (which is why I had updated my original review to 3 stars. Good customer service is rare, and they should be recognized for it). I enjoy testing and technology, so I said that I would be willing to test another unit and determine whether I just had something wrong in the original unit, or whether the mic wasn't compatible. Today, I tested it on my interview set, using all the same settings as the lapel mic I'm presently using. I'm pleased to say that performance was stellar. Good, clean signal; no hiss. The mic element has pretty good response. I haven't distance-tested it, but I suspect it will be fine, as both the transmitter and receiver have external antennas. Unlike a lot of mics, you can change frequency as well, if there is any interference. I do have one thing I wished it had: a hotshoe mount. The receiver is strictly a box. Now I know it will be easy to get some sort of hotshoe mount bought or made and glue it on -- I plan to do that (I'll probably 3-D print it)-- not a major deal. So to sum up: Fifine took a negative experience, and turned it into a VERY positive one. The mic now works perfectly; you also get a headset mount which will be useful in some situations. The price is unbeatable. To be crystal clear: they sent this unit for me to test and provide an update. I like it so much that I will keep it, and I'll put a hotshoe mount on the receiver to make it work in the field. Definitely recommended! UPDATE 7/10: I added a star for customer service. I've been discussing the problem with them. They've been VERY supportive, and very interested in a thorough compatibility test. I'm going to try it again, and I'll update this review once I do. UPDATE 7/8: After more troubleshooting, I believe the problem is that the electronics of either the transmitter or the camera are not shielded appropriately (although I suspect the $34.95 receiver a whole lot more than an $1800 camera). I've decided to send it back - no reflection on the seller, who I haven't given enough time to respond, but I need this ready next week. ORIGINAL: I just got the mic today to connect to my Sony RX10 Mark 4 for some interviews I wanted to do. I have a Sony hotshoe mic, which has beautiful sound, but it was picking up too much reverb/echo from the room. When I connected the receiver to the camera, I immediately got a loud, high-pitched screech. I dialed down the input volume a lot and moved cables. Eventually I was able to get the background noise down to a high-pitched digital-sounding hiss. It gets dramatically worse when I turn on the transmitter, even with no mic plugged in. I tried moving the cables, changing channels,playing with the volume, but I just can't get a clean signal. It just may not be compatible with my camera. I've emailed customer service a few minutes ago; I'll give them a day or so to see what they say. Since I'm planning to do my interviews next week, if they don't respond quickly, I'll probably pick up a different brand and return this one. If the problem gets solved, I'll update the review and the stars. Read more
