Maybe Vido is supplying the earbuds? The red and blue Vidos instantly got sold out here and I don't see someone selling it anymore.
Actually Vido is a computer / Android tablet brand in China and doesn't make its own earbuds. The original Vido earbud is OEMed by another factory and supplied to Vido as their stock earbud on its various tablets / computers at one point. Traceless is made by the same factory - the two uses the exact same driver and should sound exactly the same, just branded differently.
