Form 1 foam pad drawing

14 replies
Hi,

I won an internet auction the other day. It was a pair of Form 1 headphones. Since they (as do many) miss the foam pads they went cheap. I emailed one of the sponsor companies that used to sell the B&O restoration kit. But it seems it is no longer available. So I'm thinking why not try and make my own. Trouble is I don't have any reference to start from. So do any of you guys have Form1 with the pads intact and are willing to take close ups and make a drawing?

I saw online that some guy actually did retrofit Form 2 pads with good sounding results but that looks wrong I guess. And does not solve the prism like comfort foam piece above each element.

Best regards,

Mikael

I have Form 1s which were purchased from Lee's shop last year.  Lee's shop had restored them with the B&O kit so the pads are in perfect shape.

How can I help?

Hi,

Great! Since the kit is obsolete I'm thinking of making a drawing of the original foam pads and headrest supports. So I suppose accurate measurements of the two foam pieces on each side. Then some close-up pictures of the same items. Hopefully this could end up as a type of tutorial how to make your own.

Regards,

Mikael

Mikael,

I have a pair of Form 1s with relatively new pads attached that you can borrow to use as a template. If you pm me your address, I'll post them to you.

Well, let me do a first draft here.

The piece that sits on the ear is essentially a rectangle.

42 mm up and down

40 mm front to back

7 mm thick

The density of the foam that sits on the ear is a bit less dense than a pair Sony headphones I have sitting here on my desk.  The piece that sits above the ear is even less dense.

That piece has a cross section very similar to a stylus.  See two posts down.

13 mm at the base

15 mm tall

Tapers down to about 6 mm at the top, which is rounded

35 mm front to back

 

A second view

 

And a sketch of the piece that sits above the ear.  See how it has the cross section of a stylus (inverted)?

Very generous offer of Cleve.  I suggest you take him up on it, if for no other reason to "feel" the density of the foam.

A very kind offer indeed! I plan to first find sources of suitable foam material. I will get back to you after that.

Thanks! Exactly what I was looking for. Next up is trying to find suitable foam material and make some tests cutting it to shape. I was thinking buying bigger foam pads and then cutting them down to size. But if I find the stuff as raw blocks that would even be better. Suggestions are welcome ofcourse.
