Those looking for a solution to recording vocals, instruments, and voice-overs should check out the Blue Nessie Adaptive USB Mic and Audio Technica ATH-M50 Headphones Kit from B&H. The Nessie USB mic is a cardioid condenser with a built-in pop filter and features integrated and automatic de-essing, EQ, and level control. It can record in 3 different modes, one optimized for vocals, one for instruments, or flat, without any processing applied.
The Nessie has a zero latency headphone output, so you can monitor your audio with the included Audio Technica ATH-M50 closed-back, around-ear cushioned headphones. The headphones themselves have a single-sided, coiled cable with swiveling earcups for single-ear monitoring.
