As we’re currently crafting crafting the first Zeitgeist in-ears, we also give them a branding. We want these beauties to shine without any disruption, so we give them only a decent logo mark on the inside. The “Z” obviously stands for Zeitgeist, the small “power of 2” indicates the driver-set-up. The first and only power-train features two superb drivers, but there will be other drivers, so the number shows the technology inside. The logo is put only on one piece. The other one will carry the serial-number (XXX/200).
