PORTA CORDA MkIII

From the energy of two small batteries a portable player nowadays feeds us with over 30 hrs of music. However, the low supply voltage of 3V doesn't provide enough "juice" to drive many headphones properly and accordingly sound quality is rather poor.
The PORTA CORDA is a portable headphone amplifier meant to "replace" the standard headphone socket of your player. It has an internal supply voltage of 9V and thus much better driving capacities. Connecting the PORTA CORDA to you portable will simply make your headphone sound better, especially as the build-in natural crossfeed filter makes listening more natural and relaxed.
