I'm not a tourig musician, just playing guitar only in my studio and doing some rehersals with my band . This pair is Ok when you consider the money you pay. If you have a busy setup with lots of hi tech bluetooth wireless etc. pedals, there may be some noise. (I believe it depends on it's wireless technology,a more high end one may not couse that issue but hey it's onlu 49€!) if there's too much tech device and wireless mics around, it may prduce some noise. Yes I've experienced it by my own ears on some of my pedals. The USB inputs for charcing is also micro USB , which is outdated and I’d like to see a USB-C input instead, so we could use any other USB cables in the house,I don’t believe it’s a huge production cost. So I give 3 stars. BUT, I've never came across with connection error, easy draining battery or some other issues else. Also no noise problems with only 1 floorboard processors or all analog setups. In short, just be carefull to the enviroment you play your instrument, The hard carrybox is great, easy to carry in your backpack! I don't lose the units anymore. On behalf of the playing scenarios I’ve mentioned, I recommend it.
