Summary of AKG K512
The AKG K512 are rated to perform over a frequency range of 18 to 20,000 Hz. They are rated to have an impedance of 32 Ohms, like other mainstream headphones. This also means they are easy to drive on pretty much any source device, be it a PMP, a phone, tablet, PC or notebook. There’s a 2.5 metre cable that lets you sit far away from your PC. Unlike the Sennheiser HD650, which used two seperate cables to connect each can, the AKG K512 only uses a single cable. The cable is sturdy and is made of decent quality plastic. The connector on the end isn’t gold plated, but there isn’t any drop in quality that we could notice with these headphones, as compared to those using gold plated connectors.
