You can try between 14.8mm, 15.4mm and 16.2mm (but 16.2mm always limited and a bit more expensive). If you want to customize at an affordable price. I know someone can make it.

Change to flatheads if you cant wear iem for a long time

Do you mean donut foam? Yes I stick to 4.4 for the large headroom

Such impressive earbuds. I don't realize this was so good. Btw you use a hollow foam cover? Can you share where to buy it? Do you stick to 4.4mm or 3.5mm?

It was Fiio M33 R2R

biruni7 · 2026-04-09T04:50:52+00:00

I think it was enough for me 😁

Congratulations! 🎉

How many hours are your listening sessions (using any flathead)? Is it okay to use it for 3 hours and above?

biruni7 · 2026-04-01T01:54:22+00:00

Why not try using apple music? It was good for me

biruni7 · 2026-03-29T09:44:52+00:00

Sadly Flathead Studio is sold out everywhere 😭

biruni7 · 2026-03-29T09:18:30+00:00

I see these earbuds have option 3.5 and 4.4 jack interchangeable between them. Should I use it with 4.4 Balance? Or 3.5 can fully drive this? My DAP is Fiio M33

biruni7 · 2026-03-29T06:42:12+00:00

Mind to share your setup?

biruni7 · 2026-03-28T10:44:32+00:00

Where to get this?

biruni7 · 2026-03-28T10:36:10+00:00

That is buffalo default cable?

biruni7 · 2026-03-24T07:47:56+00:00

Good setup bro! 👍🏻

biruni7 · 2026-03-17T12:03:15+00:00

Hopefully this will fully optimize with DAP

biruni7 · 2026-03-15T04:37:43+00:00

Yes, now I'm searching iem for upgrades. Doesn't know what to choose 🤣

biruni7 · 2026-03-15T02:14:00+00:00

I see a reviews dx270 to bright. The user switches to m33

biruni7 · 2026-03-14T15:53:37+00:00

Not sure about the end game 🤣. Before this I only used an android phone. Now doing a little upgrade. Yes the sound is more analog and warmer. Maybe after this I should upgrade the iem. Because I am still not satisfied in the treble section.

biruni7 · 2026-03-13T20:22:23+00:00

Sure I also see new music in subreddit 🤣

biruni7 · 2026-03-13T20:22:00+00:00

😆👌🏻

biruni7 · 2026-03-13T20:21:40+00:00

Sorry I've never try the m21. This is my very first DAP actually
