I got this a few days ago. I use it strictly for dictating, using Dragon for transcription. In spite of the low price, I get better accuracy with this than with any other microphone I've tried. (No, I haven't bought one from Speechware yet. Maybe someday.)This works well with my Olympus voice recorder, and also with an Andrea usb sound card dongle in my laptop. Even with an adapter it didn't work in my phone (could be a power issue; could be an adapter issue) but it works fine with the phone using an OTG cable and the same Andrea dongle. About that OTG thing, though: trying to charge the phone at the same time created a lot of noise in my recording when I used an adapter plugged into wall current. No issues when charging from a battery, or when not simultaneously charging.In short, I love it. I'm buying a single-ear version from the same manufacturer to see if that works better as a portable microphone (this one doesn't really fold up). After I try that, I'll buy more of at least this one, possibly both, just in case something happens in the future. I don't want to be without this microphone if I can avoid it.
