With a wide frequency response of 25Hz to 18,000Hz, this microphone accurately reproduces everything from ultra-low to high frequencies. It's also highly resistant to feedback, making it ideal for live stages. - Brand: beyerdynamic - Model Number: TG V70 Thank you for viewing. I purchased this new online 2 or 3 years ago. I've only used it a few times to check the sound quality. I'm selling it to organize my equipment.
