I bought two of LC 97 TWS clip-on mics to conduct radio interviews. They are okay, but not great. I have to do a fair amount of EQ'ing at the top end in order to disguise the noise that these mics cause, which is not insignificant but rather irritating.
They serve their basic purpose for recording speech, but the disadvantages are pretty severe, so if you can afford more expensive mics, don't bother buying these.
