Lets make this happen, a baby Orpheus for the modern audiophile world. We have the Sennheiser HE 1, but no other electrostatic from the company for the audiophile that's looking for the Sennheiser sound at an (way more) accesible price. The system should be based on the HE 60 project, an electrostatic with price-consciousness in mind, as the then HE 90 (Orpheus) was too expensive just as the HE 1 is actually. And just like the 600 series it should have a good build quality but using the famous plastic that Sennheiser is known for, which we still have from the 580 Precision and it is still rock solid. And most importantly, great sound quality paired with an energizer that can deliver (more than) enough power to drive the electrostatic driver. I would suggest the name to be HE 0X (Zero X), as it's a baby HE 1 and an 'X' has always trailed on Massdrop x Sennheiser collaborations. I had previously seen that Will from Collaborations said they had already pitched Sennheiser for the HE X0,...

I've recently went through the process of removing the attached cables on my Sony MDR-V6/7506 headphones and replacing them with female audio jack. Once I got the hang of what to solder, the process was fairly straight forward. I needed to use a Dremel tool to widen the hole for the audio jack. I got some minor scratching around the area but I think it came out looking pretty good. [image] In addition to being able to use any audio aux cable to attach the headphones, I found that a Bluetooth transceiver works just as well. Once synced up to my phone, the transceiver effectively makes the headphones wireless. The transceiver even has a microphone so I can answer calls on my phone. [image] I was wondering if anyone else out there has worked on a similar type project. I'd be curious to know what headphones you detached the cable from and how much effort was involved. I'd be interested in hearing both successes and failures alike. The next pair of headphones I plan on attempting this...
