I have a query regarding my Major IV knob button – it's become a bit loose, making it challenging to turn the volume up/down or switch to the next/previous song. Has anyone experienced a similar issue or knows a reliable way to repair it?

Thu, 30 Oct 2025 12:58:02 -0700

Hey everyone, I fell asleep using the headphones and when i woke up the knob was broken and it fell out of the headphone, i (unfortunatly didn't know any better) and tried super glueing it back together, then it didn't turn on anymore.

I oppened it, and saw the glue on the knob and on the board where it sits.
I the cable/tape conector is ok, is this works with the wire and it charges.

I'm just searching for the parts to replace it.
found the knob https://www.snapeda.com/parts/SKRHABE010...
but not the board

Any idea where i can find it ?

Marshall Major IV: Marshall Major IV ear cup hinges replacement

Mon, 02 Jun 2025 10:33:03 -0700

The lower four plastic hinges on the ear cups that hold the metal wire have all cracked/fallen out entirely. Because of this, sometimes the wire will slip out of the joint hole.

I have not included my own image, but I've marked up an image to show what pieces I'm talking about.

Is there any way to replace/repair/fill in this hinge?

Marshall Major IV: Power Issue – Marshall Major IV Not Turning On

Sun, 02 Feb 2025 14:25:51 -0700

Hello,

I am experiencing an issue with my Marshall Major IV headphones. When I plug them in to charge, the indicator light turns green after about a minute, which seems to indicate that the battery is fully charged. However, as soon as I unplug them, the headphones do not turn on at all.

I have already tried several troubleshooting steps:

Using different USB-C cables and power adapters
Leaving the headphones charging for several hours
Attempting a forced restart by holding the power button for 15 seconds
Trying to turn them on while they are plugged in
Testing them in wired mode with a 3.5mm jack cable (which works)

Despite these attempts, the headphones refuse to turn on and only function in wired mode. Thank you in advance for your assistance.

Marshall major iv: Headphone not turning on

My marshall major iv headphone not turning on and not able to charge but works fine with 3.5mm audio jack cable. I'm guessing that's because battery is faulty. I found dissemble video online and battery is Li-Pol battery with 3.7V (3-pin connector). Can I just buy the same kind of battery and fix it myself (no need for soldering)? Can I just plug in the 3 pin with the little chip inside the headphone?
