As I ventured into a new band, where everyone was using in-ears, I was asked: what system do you use? The answer was: none, as I had never used in-ears. So I started reading, YouTubeing and the works. The rest of the band was using the ubiquitous Sennheiser systems and they told me: they are the best.
But, stubborn as I am, I looked further. And I started leaning to digital vs. analog.
Long story short: I think I have the best system of all of them. No drop-outs, no noise, reaching up to 30m *inside a concrete building* (going to the loo while practicing, still hearing the conversation going on), crystal clear sound - even with the earbuds delivered with the set. No latency noticed. Couldn't be happyer.
Strong recommendation. Built like a tank, easy set-up. What more does one whish for?
