The Shure SM57+X2u XLR-To-USB Digital Bundle includes the SM57 instrument microphone, and the X2u XLR-to-USB microphone adapter.

SM57 Instrument Microphone
The legendary Shure SM57 microphone is exceptional for musical instrument pickup and vocals. With its bright, clean sound and contoured frequency response, the SM57 is ideal for live sound reinforcement and recording. It has an extremely effective cardioid pickup pattern that isolates the main sound source while minimizing background noise. In the studio, the mic is excellent for recording drums, guitar, and woodwinds.

X2u XLR-to-USB Microphone Adapter
The Shure X2u XLR-to-USB Microphone Adapter is a modular accessory that connects any XLR microphone to your computer to create better-than-CD quality recordings. As home recording flourishes, the Shure X2u adapter redefines what musicians and podcasters can do in their homes and for on the go sound capture. The X2u mimics the sleek, beautiful design of Shure’s iconic SM57 and SM58 microphones and can be used unobtrusively for live and in-studio recording. The X2u microphone adapter provides phantom power so you can use your favorite condenser mic for direct USB recording.
