The APOGEE BOOM is a purple audio interface that allows you to connect microphones, instruments, and headphones. I haven't used it much, so it's relatively clean. In terms of sound quality, it's an entry-level model, and in a good way, it has a clear sound that's not typical of Apogee. Original box and cable are included. No claims and no returns. Please refrain from price negotiations. - Brand: APOGEE - Model Name: BOOM - Color: Purple - Connectivity: Microphone input, headphone output, line output - Accessories: USB cable Thank you for looking.
