Custom Cans are pleased to offer these awesome modified Sennheiser HD25-1 Mk II headphones. Custom Cans have been pulling apart and modifying the HD25 for four or five years now and after over a year of tweaking and testing, are now offering the Uber edition for sale to the general public. The HD25 have been around for 25 years and have won acclaim for their flat response, fun sound and detailed mids. They are great headphones with a brilliant reputation but these Uber edition ones have several modifications to squeeze more detail across the range and help them drop lower for better resolution in the bass/ sub bass region.

Expect orders of our Uber HD25's to be dispatched within 5-12 working days.

The modifications are as follows;

Firstly, the damping has been updated in the ear cup to make them sound more open - essentially we have removed the felt disc inside the ear cup and instead lined the inside of the cup with bituminous vibration ramping material - this stops resonance in the ear cup an helps them sound more open as there is a bit more air volume to play with behind the driver.

Next, rear of the driver and the driver enclosure has been mass loaded. As you may know every action has an equal and opposite reaction - due to the HD25s lightweight construction a fair amount of the energy from the driver goes into vibrating the ear cups. Also added are lead weights strategically placed on the driver to add extra weight in the right places to ensure that more of the energy from the diaphragm is turned into sound rather than being absorbed by vibrating the casing. This gives a lot more bass detail and makes them less boomy, you can hear a lot more texture and impact in bass lines. After all this, there was probably a bit too much bass so we have also reduced the size of the bass ports in the driver which further tightens things up and stops the bass from overpowering the mids/ highs.

Thirdly and probably most importantly the standard steel cable has been replaced with Custom Can's own audiophile cables. They come with a steel cable as standard as they are designed for use by camera men and audio pros - the steel gives the cable high tensile strength while keeping it light weight but is not great for sound quality. Some people are not cable believers and the team at Custom Cans personally believe it would be hard pressed to tell the difference from one copper cable to another but the jump from steel to SPC is very noticeable. The steel cable has a resistance of 4ohms and the audiophile cable is not measurable with a standard multimeter - this is because silver has much lower resistance meaning more of the signal from your equipment goes into making sound rather than heat. The cable is also braided by hand and covered in PTFE to protect it from RFI and EMI and has 4 cores - with separate negative cables for left and right to help a little with crosstalk or we can re-wire them to give a balanced connection for a little extra.

Plenty of testing has gone into them, please feel free to check out a review for them here:  http://www.inearspace.co.uk/inearspace/Custom_Cans_Uber_Modded_Sennhesier_HD-25-1_II.html
 

The HD25-1 II provides remarkable sound reproduction over the entire audible range and is still capable of handling high levels of sound pressure, while at the same time virtually eliminating background noise and sound leakage. The ear capsules can be rotated to facilitate one-ear sound monitoring at the turntable, and the ergonomic design remains comfortable even after hours of use.
