This is a very tidy solution that will enable you to have two people wired up with lapel mics. The units are about average size but because of the dual receiver, that is a space saver.Very impressed with what comes in the package. You get the two transmitters and dual receiver, two lapel mics with mic clips and each mic has two soft foam wind/pop shields. In addition, there are two fluffies for windier conditions. Each microphone is terminated with a locking 3.5mm jack plug, which is essential for stop leads acidentally falling out.For the receiver they have supplied two leads, both with locking 3.5mm jack plugs. One lead is a 3.5mm to 3.5mm (mostly for DSLRs), and the other terminates in an XLR connector. If you are wanting to plug this into a recorder with independant XLR's you will need to get a stereo to dual mono XLR to XLR adapter. I would recommend this so as to keep the 3.5mm locking connector in the setup.For the quick tests I have done, the sound quality is fine. It's a little disappointing that there isnt anyway of controlling the input level, so will be interesting to see how it performs under various conditions, but for the price, this isn't surprising. You can however adjust the output volume and headphone volume. Nice addition having a headphone socket as well. Range wise, I've found them to be pretty solid up to around 50m line of sight.The only thing I would say needs pointing out is the operating frequency. When this arrived I noted the frequency range of 538-594Mhz in the manual. This requires an Ofcom PMESE License to operate in the UK. You can purchase 48hr licenses (per transmitter) if you advise on location, or buy a yearly license (per transmitter). For the dual receiver/transmitter pair this equates to an annual license of £158. This should have been spelt out in the description.
