BGVP's will be launching their 1st pair of TWS, the Q2, on Kickstarter sometime next month. Think it will be priced at USD$75. Its already for sale on taobao at RMB$560.

Interesting concept since the Q2 is dual purpose, meaning it can run on either wired or wireless. BGVP has previously released some really good sounding iems but they have a track record of piss poor QC(mainly mmcx connector issues). The Q2 uses mmcx for wired so dont think i will jump on this one as soon as its available for sale.
