This is my Sennheiser HD598 with custom replacement audio cable. The original cable was too long and has 6.3mm plug. I mainly use as my daily driver, so mobility is important. My source is my HTC One (M7) with FiiO E18 amplifier with 3.5mm socket.
This blog is currently on hibernation. I have no chance to update you with anything about traveling via Batangas Port. I am currently out of the country.
