Why don't you do what I did, buy 2 cheap large headphones , strip them and build small diaphragm, and use small neos, and 2.25 mm wide aluminium foil, fix it all together total weight 405 grams. They sound wonderful. Can listen to music all day, and watch tele with them on. No problem. Everything sounds so natural it is unbelievable. Am buying more cheap headphones to convert.!!

James: I'm very interested in what you did there. What is the aluminum foil for exactly? Would you be able to post pictures?

Rem: I've been experimenting with cup designs-- fitting the neos to my ears at the perfect angle-- by building up this stuff I bought at my hardware store called "sponge rubber weatherstrip." I've found with this stuff, (unlike the leather pads that came with the monoprice cans) that a certain balance can be achieved between placement and band extension which makes them acceptably wearable, even bordering on comfortable, despite their weight. When using the leather pads, I would often find sharp pains on the top of my head in the exact location the headband was resting... hmm...

Edit: Sponge rubber weatherstripping is identical to what some people use to seal speakers in boxes as apposed to that grey glue stuff. I bought some from PE. From what I can tell it is 100% identical, but can be had for less at a local hardware store.

Have started on next rebuild smaller than these, so maybe too difficult to finish we shall see he said more in hope than anger.! I think I have bigger ones coming we shall see, today or tomorrow? I don't do a double diaphragm at the moment, a single one is hard enough as the ease of the layout depends on what you receive in your cheap headphone carcass! I suppose I am very lucky in the amount of time I have being retired, still one must use ones time left!!

Great pictures!

The 2.25mm aluminium foil, where did it come from?
Is is self adhesive (sticky back) ?
Is it one continuous strip even round the U-bends, if not, how do you ensure reliable conduction between multiple strips?

cheers!

the 2.2 mm was cut by my hand, right down from 9 mm, it is self adhesive and is in one continuous piece. Not a good idea in separate strips!! To get more sensitivity I may cut the 3 mm tape in half and use that in the epsilon type layout. This increases the impedance and the sensitivity, killing 2 birds with one stone.
