XSONIC is a Chongqing, China-based audio gear company (Chongqing XSONIC Technology Co., Ltd.) that designs smart controllers, audio interfaces, and looper pedals for guitarists, bassists, and producers. The brand is best known for its AIRSTEP line of compact MIDI/Bluetooth foot controllers, which ship in dedicated editions tailored to specific amps and modelers — including versions for the Neural DSP Quad Cortex, IK Multimedia TONEX, Boss Katana, Positive Grid Spark, and Yamaha THR-II.

Their XTONE series of smart audio interfaces, including the XTONE, XTONE Pro, and XTONE Duo, targets guitarists and vocalists working with amp-modeling apps on iOS, Android, Mac, and Windows, combining an instrument input and XLR I/O with assignable footswitches for hands-free control. The ULooper is a dedicated looper pedal designed to sit in an amp's effects loop and preserve loop audio when the player changes amp presets or channels.

XSONIC products are sold direct through xsonicaudio.com and through retailers such as Guitar Center, zZounds, and Warwick's European shop, and the company maintains an active user community through Facebook groups and firmware updates for its controllers.

XSONIC has 6 products cataloged on Equipboard, including Switch Effects Pedals, MIDI Foot Controllers, and Looper Effects Pedals.
