I have no experience but this looks so cool and maybe doable:) I have read a ton of this thread and making this open source was so cool. What people have done is amazing.

Can someone educate me on the pros and cons of hiRose connectors versus 3.5mm. Do you have sources for each connector and recommended cables?

Thanks.

Seems like i some how forgot to post my build. About a year old by now. I really like them but at 550g its quite a strain on the neck during long sessions for me.

Really good looking cups :). I like how you kept one ring red and the other black for 'right/left' as well. Clever!

Thank you! The pictures really does not do them justice. Its a special color plastic that was used to print them. In sunlight it turs coral green, looks stunning when you have them in hand and turn them towards the light.
You can kind of tell from the picture that there is something special about the color... The green specks in the last pic :)

Hello :)

PreS: the first post on this forum, English is not my first language.
noob question: if someone (me) is to redesign the baffle, do you think one should be able to use the same cups for a pair of dynamic drivers? (dt220 that are in questionable shape) Would that work? would other modifications be needed?

Thanks!

Anyone tried some pad rolling? I’ve used alpha pads and ori pads in the past, but recently tried angled ether and I REALLY like what they’ve done! Clarity and soundstage have both increase. Bass is a bit less, but also a bit less muddy.

I'm confused about parts and construction if someone can help me please. I have printed the two part baffles and cups. I still need:

- 2.5mm headphone jacks. Would these work? https://uk.farnell.com/multicomp-pro/mj-165h/socket-2-5mm-jack-2pole-pk2/dp/1267391

- Sound damping foam - Akasa paxmate is mentoned which is 4mm think, it is quite expensive, anyone got a cheaper alternative? Could you use a cheap mousemat for example?

- Some kind of "wool felt" or "closed cell foam" to surround the baffle on the ear side - anyone got a recommendation for this? Can the same material be used as the foam above?

- "Soft closed cell foam" to make a gasket, any recommendations? i don't want to use silicone!

Are those the main parts required apart from earpads and cables? Did I miss anything?


Thanks for any help!

I just used Silverstone foam for everything, including the gasket and ear side baffle However it doesn't seem available anymore (well it is, but much more than the $20 I spent on it

Not sure about the connectors. I spent the money on hi-rose

OK thanks. I bought the akasa paxmate and will try and use it for everything. Just need the 2.5mm connectors now.

I am also interested in what people used for gasket material. I would assume that it has to compact to be very thin? I probably will be opening and closing several times for tuning so would prefer not to use silicone.

I've used 1.5mm craft foam and 1mm silicone sheet; the silicone sheet is super easy to use, seals well, is reusable, and is easy to cut.
