LETSHUOER S12 PRO gets all-new Deep Space Blue ear shells. LETSHUOER has updated the tuning of the LETSHUOER S12 PRO and ensures it gets a balanced sound Profile with a punchy lower end. They have also redesigned the acoustic structure with vent holes on each side of the chamber optimising the ear pressure build-up. The main upgrade with the LETSHUOER S12 PRO over the original S12 would be the cable. With the new LETSHUOER S12 PRO, LETSHUOER bundles a high-purity silver-plated monocrystalline copper cable with swappable termination plugs!!
