CMF Buds 2: Hey everyone, I need some expert advice on curing/solving the cut side

Tue, 19 May 2026 14:39:08 -0700

A double-sided flex cable has torn right at the edge, immediately next to a small SMD capacitor. This section is supposed to connect the mainboard to the battery side. Because the tear happened right at the edge, the original soldering pads on the flex are completely ruined/missing.

The Goal: > I want to safely find the correct paths to run jumper wires from the remaining components/board to the battery terminals.

My Questions:

Since the flex is double-sided and the edge is ruined, what is the correct step-by-step method to use a multimeter (Continuity, Resistance, or Diode mode) to accurately identify which side of this SMD capacitor connects to Ground (GND) and which side connects to the positive line?

How can I verify that my new jumper connections are 100% safe and correct before I actually connect the lithium battery, to prevent blowing up the charging IC or causing a short?

What I've done so far was connecting the FPC to the main board, and by using a multimeter I've found that the red side of the capacitor goes to ground.

Nothing Ear (2): Help identifying 5-pin SOT-23 IC ( “AK3T7”) on Nothing Ear 2024 case

Fri, 08 May 2026 01:10:38 -0700

Hi all,

I’m trying to identify a small 5-pin IC on the flex PCB of a Nothing earbud charging case (Nothing Ear).

Details:

Package: SOT-23-5
Top marking: AK3T7 (or very close)
Location: on flex cable going to pogo pins (earbud charging contacts)

Issue:

Right earbud not detected
Voltage drop only on right side when flex is connected:
- Left side: ~4.2V (normal)
- Right side: drops to ~3.8V under load

What I tested:

Disconnect flex → both sides read 4.2V
Connect flex → right side voltage drops
Removed the IC → voltage returns to normal
BUT detection LED no longer lights up without the IC

Observations:

Pin 2 = GND
Pin 4 ≈ 3V (input)
Pin 5 ≈ 3V (output)
Likely has EN/control pins

Also found a damaged resistor connected to VOUT, which may have caused the failure.

Questions:

What IC could this be? (Load switch? Power distribution? Detection IC?)
Any known equivalents or replacements?

Photos attached.

Appreciate any help 🙏

CMF Buds: What size Mesh filters do I need to buy?

I have the CMF buds pro 2, and I was noticing that my earbuds were so quiet I could hardly hear then anymore. I cleaned the mesh filters and they are now as good as new. However, I am now going to need to replace the filters at some point, and I was wondering what size of mesh filters I need to buy.
