For my 1000th post, I've got a question for those who have assembled or modified their own earbuds -
Do you have a list of the drivers, shells, & "tuning cotton" you've tried - and your impressions of their sound?
As of 19-AUG-17, I've used these four drivers:
1.) "16mm Headphones accessories Subwoofer Speaker unit for diy earphone headphone headset" -

Used in modified MX500 shells, with a Y2 thickness of the "Y2/Y3/Y4/Y5/Y6 Earbud headphones horseshoe tuning cotton" -
https://www.aliexpress.com/item/Y2Y...eaker-unit-complex-for-mx500/32809374899.html
These sounded pretty good overall, but didn't have as much low Bass as #2, so I removed them from the MX500 shells, and haven't decided how I'm going to use them.
2.) "15.4mm speaker unit earphone driver bass" -

Used in modified MX500 shells, with the "Aipinchun Diy Earphone Unit Tuning Cotton Dust-Proof with Self-Adhesive Glue for MX500" -
https://www.aliexpress.com/item/Aip...Self-Adhesive-Glue-for-MX500/32807669592.html
These were the two sets of earbuds I assembled for a co-worker's sons, so I didn't listen to them for very long.
They seem to have good Bass, and a balanced Midrange & Treble.
3.) "15.4mm speaker unit earphone driver vocal" -
https://www.aliexpress.com/item/15-4mm-speaker-unit-earphone-driver-bass-vocal/32477644538.html
Used in MX760 shells, with a Y2 thickness of the "Y2/Y3/Y4/Y5/Y6 Earbud headphones horseshoe tuning cotton".
They have nearly as much Bass as the "Bass" model, and a balanced Midrange & Treble.
4.) "15.4mm speaker unit double unit hifi moving coil Tri-band equalization "-
https://www.aliexpress.com/item/15-...band-equalization-1pair-2pcs/32800609693.html
Used in MX760 shells, with a Y3 thickness of the "Y2/Y3/Y4/Y5/Y6 Earbud headphones horseshoe tuning cotton".
They have a bit less Bass than the "Vocal" drivers, and good Midrange & Treble.
I will be trying some additional models of drivers and shells - ordering some different 15.4mm drivers, and also some smaller 14.8mm drivers, along with PK1 / PK2 shells.
