This is a modified pair of Sennheiser HD650 headphones, complete with mass loaded drivers and a custom ultra-low capacitance cable for balanced input and a stock cable for unbalanced stereo input.

The modifications to the drivers provide extended detail and control in the bass, to match the already crisp mids and highs. The HD600 and HD650 have been a very popular option for use with the pono but their high impedance makes them tricky to drive as standard - running them in balanced mode means you are using both the amps in the pono - so you have one amp powering the left ear and one powering the right. This helps the pono player drive these great headphones to their fullest. The modifications we make to the driver makes them slightly more efficient as well.

This pair comes with one of our audiophile grade, ultra-low capacitance cables with Cardas HPSC connectors at one end and a balanced connection of your choice at the other, such as the PonoPlayer or balanced XLR amps. This 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 capacitance 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.

In addition to the balanced litz wire cable, we also supply the stock cable, so the headphones can still be used out of the box on traditional 3.5mm or 6.35mm stereo equipment.

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.

Over 60% of our customers are outside the UK, so we have a lot of experience with shipping worldwide, offering the same great service to suit your needs such as tracking.

Expect orders of our HD650s to be dispatched within 5-12 working days. >
