The ability to use this with your favourite microphone is a dream come true. My road crew want a stack of them to replace every XLR cable that we use. PRO: Makes my favourite mic' (previously wired...sorry not a Sennheiser) sound even better. No buzz. No drop-outs. No cables. No fiddling with frequency changes. No radio interference. The radio compression smooths out the difference between my quiet speaking voice and my loud singing voice. (My sound engineer loves that) I researched all kinds of replacements for my Sennheiser radio mic, that was smashed, and then this came on the market. This has freed me from the cables forever. A fabulous product. Not only would I recommend this product, I've already called all my musician friends and done so. CON: None yet. Time will tell if the rechargeable battery system holds up but for now they work great. BOTTOM LINE: I would recommend this to a friend.
