Dimensions for Elear DIY Cable Builders
Well...that escalated quickly.
Anticipating incoming Focal Elears, DIYers are already starting to ask about dimensions for cable swaps. Might as well do it while I've got them here.
The above photo shows the diameter of the connector housing at a girthy 9.67mm.
The entry hole in the Elear capsule housing is just over 10mm.
Depth of the hole is 10mm.
There is a detent in the hole. It appears to be a plastic part and pushes in with moderate effort. I can't get my calipers on it but I'd guess it's about 1.3mm in diameter and length.
There is an annular groove around the connector body to engage the detent. It's diameter is 8.67mm.
The 3.5mm TS plug appears to be of normal size. I did confirm that the tip is hot and the sleeve is the return to ground.
I tried to fit a Rean 3.5mm plug I had. It did seem to interfere slightly with the detent, but it did depress the detent and slide in all the way. The fit seemed really nice. I'd suggest the Rean NYS226BG.
SBAF member PoochZag posted that he contacted Focal for additional information and received this information:
Thank you for your inquiry regarding our Focal Elear and Utopia headphones. On the Elear we are using a standard 3.5mm locking connector. The locking portion is a small ball bearing lock that engages into I small ring around the 3.5mm connector. I have included a picture to help explain this protocol.
Regarding the Utopia, we have changed the connectors on both ends. Due to the high quality of this headphone, we have decided to use brand name Neutrik and Lemo connectors. We are using the Neutrik connector on the source ¼” end and the Lemo connectors for the headphone connection. As per the electrical pin outs, I have only been able to play around with the prototypes up to this point.
We are just about to start shipping limited quantities of production models and will have more information in the future. What I can tell you is that we are using a two pin connector that only locks in one direction, and with the prototype units the positive lead was on the outside of the headphone. I’m sorry that I cannot provide any further information at this time, but as I mentioned, I will have more information as we are able to get more hands on with production models.
