Description

This is a modified pair of Beyerdynamic DT990 headphones, complete with 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 changed the wire around the headband that takes the 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.

This pair comes with one of our audiophile-grade, ultra-low capacitance cables with a mini-XLR at one end. At the other end a balanced connection of your choice, such as the PonoPlayer or balanced XLR amps. This audiophile cable is made of four wire cores individually wrapped in paracord. Each core consists of 84 strands of individually insulated copper wire. This gives a lower resistance than most OFC cables (less insertion loss). The resistance for this cable varies depending on the length and connector type. It 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.

In addition to the balanced litz wire cable, we modified the stock cable with a 4-pin XLR. The headphones can still be used out of the box on traditional 3.5mm or 6.35mm stereo equipment. This cable is only included in the balanced version.

Please note that this listing only includes balanced connectors. If you need single-ended connectors such as a 3.5mm or a 6.35mm then please take a look at our unbalanced listing: Link
If you are unsure as to what a balanced connection is then please refer to this guide.

All of our modified headphones are made to order. They will take between 2 and 4 weeks to make, then you will receive an email once they have been dispatched.

We also offer a range of optional extras including various coloured ear pads and a carry case from Beyerdynamic.

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.
