I purchased this microphone to use for online piano lessons. Reading the reviews it sounded like it would be a good choice. I have used this for about 4 1/2 months and the sound quality that is being received is muddy at best. It also has a problem with the sound volume: the sound goes up and down -first loud then suddenly it drops low. I've gone over the manual and don't see any way to make any adjustments. I've tweaked my computer settings so that there is no automatic volume adjusting going on. So I contacted the manufacturer. The only way to reach them is by entering your request through their website. The only response I got was their request to send them a copy of the invoice to make sure I purchased the mic. After that...nothing. No response to repeated requests for assistance. So, if you purchase this microphone and it is defective DO NOT expect any help from the manufacturer. I now own a $50 paper weight. Buyer beware.
