As part of the grand opening commemoration for Chinese urban lifestyle retailer Source and its newest flagship store in Beijing. California-base headphone manufacturer Aerial7 asked 2 of the world's best known sneaker customizers, METHAMPHIBIAN (METH) and RoyaleFam's SBTG, to try their hands on creating the label's very first collaborative headphone. Forging among inspirations from vintage analog headphone to digitally tuned audio, the duo created 2 limited edition models based on Aerial7's popular Chopper2 Headphone. Each bears the signature design of the artist, from the paint splashes of METHAMPHIBIAN to the eerie portraits from SBTG. In addition, the headphone's 44mm driver offers the precise tunes in all ranges. And as with all Aerial7 Chopper2 Headphones, the METHAMPHIBIAN (METH) and SBTG Limited Editions offer a discreet microphone, making it ideal accessories for recording devices and mobile phones. The Aerial7 x METHAMPHIBIAN x SBTG - Limited Edition Chopper2 Headphone Collection is available exclusively through Source's new Beijing flagship store.
