Finally somebody thought of it AND made it happen! I just got this system and I was a little hesitant, considering how inexpensive it is. I mean, come on! A wireless system AND an in-ear system, all in one, all digital, and for under 200 bucks? Is anybody from Shure, Sennheiser, AKG, Beyerdynamic etc. listening? Anyway, I was especially concerned regarding latency, and about how long a charge will last. The first issue is none, there is no noticeable latency whatsoever. The second issue can easily be fixed by purchasing one of the superfluously available external battery charger packs that are available for cell phones and tablets. Depending on your wireless pouch on your guitar, you can expand the system with a 20,000 mAh battery which should last throughout even the longest gig. The system is incredibly compact and sounds great. I can imagine that the range of the system might become an issue if you play stadiums, but then you shouldn't be in the market for a $200 wireless. Anyway, I will keep using the hell out of this system, in rehearsals, gigs, practicing; heck, I might even record through the thing. If it doesn't sound any worse than my best cables, why go through the hassle get all tangled up in wires. If you don't see an update from me within a year, that means I'm still extremely happy with my purchase. I'm facing a six month contract abroad with 6 shows a week and 4 sets a night. Expect me to use that sucker every night.
