Behringer Ultralink ULM202USB Wireless USB Dual Microphone System for Podcasting, Streaming & Recording - Professional Studio-Quality Audio Solution

After 2 years using these mics in my basement studio, they maintain the 5-star rating. Low noise, great range (30ish feet in our practical range), never a dropout, and solid sound. I even tested micing a guitar cabinet with this against a wired Beta 57a and while the B57 predictably sounded better, the ULM mic sounded MUCH better than I expected; a little darker than the B57 but with nice articulation and detail if lacking the presence of the Shure. Certainly useable for recording a rehearsal if not for actual demo tracking.My only real complaint is that the mics will eat batteries even when they're "off", so take out the 2x AA in each mic when they're not in use and you're all set.Original review:Got these mics to use with my Behringer QX2442USB mixer. The dongle plugs into the USB port between channels 1 and 2 and connects immediately. The sound is clear and noise free. I haven’t noticed any WiFi interference, but mostly everything is on the 5GHz band at this point so not much crossover on the lower bands.Sound-wise, I tested vocals using one of these versus a wired SM-58 and they’re was almost no difference. The 58 had very slight more presence in the midrange, but a channel EQ tweak the difference was imperceptible to my ears.A nice option to get some wires out of the way for rehearsals, especially if you have a compatible mixer.
