SaramonicBlink500 B2W Dual-Channel 2.4GHz Wireless Lavalier Microphone System 2 Transmitters with 1 Receiver for DSLR Canon Nikon Camera iPhone Android Phone Video Podcast Live Stream

I did a test around a football pitch a couple of days ago, walking and talking (and a lot of heavy breathing) and the audio never dropped out, using one of the supplied lavalier microphones. When I listened back to the audio is sounded very good, the audio quality was very usable. The reason I purchased the B2 was for commentary team / interviews during football games, (fed up with XLR, Mics, cables and connections,) the more connections you have the more likely your risk of failure! (We can call that Vinnie's theory!) If you have checked out the propaganda on youtube etc, it says one of the failings of the Saramonic B2 is the inability of the units to adjust the two microphones levels individually, (as the audio is sent to the receiver in a take it or leave it fashion!) well I don't think that that (love using the same word twice in succession!) is a problem, as the gain can be adjusted on each of the transmitters, so if one of your victims has a louder voice than the other, adjust the gain accordingly; up or down. These units are smaller than a match box and so light you might forget you are "On Air." I love the idea of the in-built batteries, it took me less than an hour to charge them fully, but they last for ages, (Specs say 8 hours). They should run all day and if power is running low any USB 'C' charger / power-bank will keep you going. For anyone who's mad into unboxing, (God help us!) you will be impressed by Saramonic's nice finish in the product presentation. I'm delighted with the purchase and I'd gladly recommend!

So clear! Works really well we tested it and walked around my house and garden and the mic still picked up sound!
