Irin is a budget music-gear label from China, registered as a trademark by Sun Jianjun and operated out of Yiwu. The brand covers a wide catalog of low-cost instruments and accessories, including electric guitars, ukuleles, mandolins, melodicas, violins, tuners, strings, picks, and a large line of mini guitar effects pedals spanning distortion, overdrive, fuzz, chorus, delay, reverb, tremolo, EQ, and amp/cabinet simulators.

Rather than selling through a dedicated storefront, Irin reaches players through marketplace listings on AliExpress, Amazon, Walmart, Reverb, and eBay, as well as third-party retailers and drop-shippers. The effects pedals in particular are the products most often discussed online, with examples like the Pocket Metal, US Dream, Vintage Overdrive, and the AN-40 10-band EQ. Players familiar with budget Chinese pedal makers often compare Irin's enclosures and circuits to designs from brands such as Joyo and Caline, and some units have been identified by the community as rebadged versions of those pedals.

Irin's niche is entry-level affordability: the range targets beginners, hobbyists, and players building a pedalboard on a tight budget rather than working professionals, and the brand has no notable signature endorsements or artist associations.

Irin has 5 products cataloged on Equipboard, including Harmonicas, Solid Body Electric Guitars, and Fuzz Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock, Folk, World, & Country, and Metal. Notable users include Gustav Larsson.
