This is a modified pair of Beyerdynamic 80ohm DT770 studio headphones, complete with dampened ear cups, mass loaded drivers, a 4-pin mini-XLR socket, a custom ultra-low capacitance cable for balanced input and a modified stock cable for unbalanced stereo input. 

The modifications to the drivers and ear cups provide extended detail and control in the bass, to match the already crisp mids and highs. The addition of the 4-pin socket allows the cable to be detached, so it's easier to use the headphones on a range of sources, while making them more portable and easy to store. We also change the wire around the headband that takes signal to the right ear cup, replacing it with paracord covered litz wire, which matches our custom cables and provides a lower capacitance for better timing and sound.

The audiophile cable is made of four wire cores individually wrapped in paracord, where each core is made of 84 strands of individually insulated copper wire, which gives a lower resistance than most OFC cables (so less insertion loss). The resistance for this cable varies depending on length and connector type, but is typically 7.5-40pF up to lengths of 2m. The cable can be made in either one or two paracord colours, for either a solid colour or stripe/two-tone look.

We also offer a range of optional extras including various coloured ear pads and a carry case from Beyerdynamic (the stock ear pads are grey valour).

All our cables have a 2 year warranty. If you experience any problems beyond 2 years we offer sensibly priced repairs. This is true of alterations too, so if in the future you need the cable to be shortened or re-terminating for a new amp we can do that for a sensible price as well. We will cover the standard warranty of any new Beyerdynamic headphones.
