Yes.
The JH13Pro, a favorite among audiophiles, will be the first IEM upgraded to new driver and crossover technology. The JH13v2 will be formally announced January 2016. The JH13v2 will feature six all-new Balanced Armatures, Steel Tube Waveguide, and Moon Audio 4-pin connector and cable, with 10 db of adjustable bass per ear! The JH13v2 has every thing you loved about the JH13 with enhanced extension, clarity and soundstage. Sonically, the JH13 is nothing short of remarkable!"
