Manufacturer's Description from Blue

The Baby Bottle is a classic modern microphone made the old-fashioned way, without compromise. Following in the footsteps of our flagship Bottle mic system, the solid-state class A discrete Baby Bottle is truly a chip off the old block.
The Baby Bottle is a pressure-gradient cardioid condenser microphone that employs our edge-terminated single-membrane large diaphragm capsule. Enclosed within a spherical grille, the side-address capsule can be positioned in the smallest of spaces. Please note that, unlike some Blue microphones, the Baby Bottle capsule is not designed to rotate, swivel, or move in any direction.
The Baby Bottle features a Class A discrete transformerless amplifier. The Baby Bottle’s character is especially rich in midrange response, making it an ideal choice for recording vocals, drums, electric guitar, and most acoustic instruments including difficult sources like saxophones, flutes, and stringed instruments.
The Baby Bottle’s unique sonic signature has a rich and present midrange response, a smooth top-end and neutral bottom-end creating an extremely present classic and contemporary sound. It is an ideal choice for recording vocals, room mixing for drums, electric guitar amps, and difficult brass instrument sources like saxophones and horns. With a unique proprietary circuit polarizing the capsule film at 100 volts, the Baby Bottle yields large output, creating the quietest microphone in its class.
