 The Verdict: It is a Hardware/Compatibility Issue

  Since the headphone's light is on, it means the physical connection is
  drawing power. However, because the Mac cannot see any device connected in
  the USB system tree, the data lines are not communicating.

  This usually happens due to one of three reasons:

  1. Passive Headphone (Most Likely): The headphone is "passive" (meaning it
  has no built-in DAC/converter chip and relies on the host device to send an
  analog audio signal over Type-C). Macs only output digital audio over Type-
  C. If the headphone doesn't have an active DAC chip, it will light up
  (taking power) but the Mac will never see it as an audio device.
  2. Damaged/Dirty USB Data Pins: USB-C ports have separate pins for power
  and data. The power pins are working (which is why the light turns on), but
  the data transfer pins on either the headphone plug or your Mac's port are
  dirty, bent, or damaged.
  3. Faulty Headphone Controller: The internal microchip inside the headphone
  that handles USB communication has failed.

  ### What you can do next:

  • Plug it in upside down: USB-C is reversible, but sometimes worn-out pins
  on one side of the plug prevent a data connection. Flipping it over can
  sometimes work.
  • Clean the port: Check your Mac's USB-C port for pocket lint using a
  wooden toothpick or a can of compressed air.
  • Test on another device: Plug the headphones into a smartphone
  (Android/newer iPhone) or another laptop. If they don't work there either,
  the headphones are faulty or passive.

> the headphone works on all devices it is sonny house headphone wireless (and
  can act via wire type-c also). It may be due to: Mac's port are
    dirty, bent, or damaged. because i can not split charger on my mac, if I
  remove charger, it is closed, and it acts always on 1% charge. So how to fix
  issues of M1 ports ?

  This provides a lot of crucial context!

  If your Mac immediately shuts down when the charger is unplugged and always
  displays 1% charge, this indicates a severe power delivery or battery issue
  rather than just a dirty port.

  Let's check the current health and status of your Mac's battery and power
  management controller (SMC) first to see what is failing. I will run a
  diagnostic on the power subsystem.

● Bash(pmset -g batt; echo "---"; system_profiler SPPowerDa...) (ctrl+o to
expand)

  The battery diagnostic shows:

  • State of Charge: 1%
  • Status: "AC attached; not charging"
  • Detailed failures: "present: true" (which means macOS is flagging a
  hardware failure on the battery itself).

  Let's read the rest of the battery health information (such as cycle count
  and condition status) to see if the battery has completely failed.

● Bash(system_profiler SPPowerDataType | grep -A 10 "Health...) (ctrl+o to

  Let's check the AC charger info to see if the Mac is receiving enough
  wattage to negotiate charging.

  Analyzing Power & Charging
  Based on the hardware diagnostics I just ran on your Mac, we have
  identified a major hardware failure in the power subsystem:
  ### The Diagnostic Results:
  • State of Charge: 1% (AC attached; not charging)
  • Condition: Service Recommended
  • Detailed Failures: present: true (macOS has flagged an internal hardware
  fault)
  • Cycle Count: 1
  • Maximum Capacity: — (The Mac cannot read the battery's health at all)
  • Power Source: 30W USB-C Power Adapter (connected, but charging is
  disabled)

  ### How this connects to your USB-C / Headphone issue:

  On Apple Silicon (M1) Macs, the USB-C ports and the charging system are
  managed by the same controller chips (CD3217 chips) on the motherboard.
  1. Emergency Power Mode: Because your battery has suffered a hardware
  failure, your Mac is running in a restricted power state. To prevent the
  computer from drawing more power than the 30W charger can supply, the Mac
  may disable or restrict the USB-C data lanes.
  2. Physical Short Circuit: If one of the physical pins inside the USB-C
  ports is bent or damaged, it can cause a short circuit. This short circuit
  can block both data transfer (stopping the headphones from being
  recognized) and power negotiation (stopping the battery from charging).

  ### How to Fix M1 Ports & Charging Issues
  This is 100% a hardware issue, meaning no software updates or system
  settings can fix it. However, here are the troubleshooting and repair
  steps:

  #### 1. Perform a Controller Reset (SMC equivalent on M1)

  Apple Silicon Macs do not have a manual SMC reset button, but you can force
  the system controller to reset:
  1. Shut down your Mac completely.
  2. Close the lid for at least 30 seconds.
  3. Plug in your charger, open the lid, and turn the Mac back on.
  #### 2. Physical Port Inspection (Check for shorts)
  1. Turn off the Mac and unplug the charger.
  2. Shine a bright light (like a phone flashlight) into both USB-C ports.
  3. Look closely inside: Are any of the tiny copper pins bent, touching each
  other, or covered in dark residue (burn marks)?
      • If pins are touching: This is a short circuit. Do not plug the
      charger back in, as it can cause further damage to the motherboard.


  #### 3. Professional Hardware Repair (Required)

  Since the battery diagnostic reports Detailed failures: present: true and
  Cycle Count: 1, you will need to take the Mac to a repair shop or Apple
  Service Provider. They will need to:

  • Replace the Battery: The internal battery circuit has failed.
  • Diagnose the USB-C Controller: If the ports are damaged, they may need to
  replace the USB-C port connectors (which are modular on the M1 MacBook Air
  and can be replaced easily) or repair the CD3217 charging chips on the
  logic board.

  ### 2. Expected Prices (Estimates for Egypt)

  Since Apple AASPs import original parts, prices fluctuate with the currency
  exchange rate, but here are the current estimated costs:

  ### ⚠️ Critical Advice Before You Go:

  1. Try the Battery First: Since the battery shows Detailed failures:
  present: true, it is highly likely that replacing the battery will
  immediately resolve the USB-C port issue as well, as the Mac will exit the
  restricted emergency power state.
  2. Apple Center Policy: If you go to an official center (like Tradeline),
  they will run a diagnostic and give you an official quotation before they
  begin.
  3. Backup Your Data: If the Mac turns off immediately without the charger,
  back up your critical files to the cloud (Google Drive, iCloud, etc.) right
  now while it is still plugged in. Sometimes, during battery replacements or
  diagnostics, the system has to be wiped or reset.
