Hi all,
Sorry for being absent from the forum for awhile. We have been busy with other design/fabrication projects, but rest assured we are still making iSine clips for our Head-Fi friends. The latest design is clip only, and is made to fit into ear-hooks found online from amazon or aliexpress. As many of you know, we started experimenting with different 3-D printed designs in collaboration with a few dedicated and passionate head-fi members out of our shared frustration with the manufacturers' clips (both Audeze and Monoprice). The current design, which uses the amazon/aliexpress ear-hooks, is the one we settled on as most practical, durable, comfortable, and versatile for different ear sizes. We tried making custom ear-hooks, but that was way too much effort and didn't turn out any better than this combo. Head-fiers buy their own ear hooks and experiment with a couple varieties.
Some have asked why we just make the clips and not the finished earhook-clip combo. The reason is two-fold: (1) I cannot make injection molded ear hooks in small quantities as inexpensively as those you can simply buy on amazon/aliexpress, (2) I am able to mail the clips internationally in a regular envelope and avoid the higher parcel package shipping costs. So, the most cost-effective solution for the Head-Fi community at these small volumes is to buy the ear hooks from Amazon or Aliexpress, remove and discard their clips, and replace with our clips.
Making replacement parts on 3-D printers is reasonable for those of us here on the forum, but it's not a cost-effective long-term solution to the manufacturers problem. However, now that there are a number of us in the Head-Fi community who are happy with the robustness and fit of our solution, I am going to contact Audeze (and Monoprice) and share our earhook-clip solution with them. Hopefully they will be interested in listening to what we have learned. I will report back if progress is made with the manufacturers.
Lastly, for those of you who have been curious about the 3-D printer in our shop that is being used to make the clips, here is a picture of our modded CR-10S.
Please continue to PM me with questions.
Best regards,
Frank
