This is a top-quality handheld vocal microphone designed for live use, featuring a large-diaphragm like the professional recording studio standard, the AT4050. - Brand: audio-technica - Model Name: AE5400 Thank you for viewing. I purchased this new over 10 years ago. The internal pop filters (grille and body, two locations) have deteriorated over time and have been removed. Please check photos 5 and later. I have confirmed its operation in the studio, but as it is quite old, please purchase only if you understand this. Also, as this is a condenser microphone, it will not produce sound unless phantom power is turned on. If you are unfamiliar with phantom power, please refrain from purchasing to avoid any issues. Please check the condition of the scratches and stains in the photos. The set includes only the microphone body and the outer bag. Feel free to ask any questions. I will add more pictures if needed.
