    Your detailed description of the issue is very helpful, and it seems you've already done extensive troubleshooting. Here's a breakdown of possible causes and steps to identify or resolve the problem:


    1. Microphone Position and Wind Noise

    • Potential Cause: Background noise such as wind can result from improper microphone placement or sensitivity settings. The microphone in the Schuberth S3 helmet might be more sensitive compared to your previous setup, amplifying wind or ambient noise.
    • Solution:
      • Ensure the microphone is positioned as close to your mouth as possible, ideally shielded from direct wind.
      • Test with a different mic sock or wind shield to reduce wind noise.
      • Try speaking with the visor fully closed, as open visors often increase wind turbulence.

    2. Intercom Settings

    • Potential Cause: Certain settings, such as HD Intercom, may exacerbate background noise or interference at high speeds.
    • Solution:
      • In the schuberth device manager, disable HD Intercom and Multitasking Audio. Test the connection again in both Bluetooth and Mesh modes.
      • Use Mesh mode in Open Mesh Channel settings or try adjusting to a Private Group to limit interference from other devices.

    3. Electronic Interference from the Motorcycle

    • Potential Cause: Electronic systems in the BMW R1200 GS Adventure, such as the alternator, ignition system, or onboard electronics, may emit RF interference affecting intercom performance.
    • Solution:
      • Temporarily turn off unnecessary electronic systems (e.g., heated grips, auxiliary lights) to test for interference.
      • Move the helmet and SC2 module further away from electronic components (e.g., test pairing off the bike).

    4. Firmware and Hardware Issues

    • Potential Cause: A hardware defect in the SC2 module or its firmware could cause audio anomalies. The fact that others with the same model experience similar issues suggests a potential design flaw.
    • Solution:
      • Confirm with Sena support if firmware version 2.2 has known issues with Mesh or Bluetooth at high speeds.
      • Request a replacement or evaluation of the SC2 module if hardware defects are suspected.

    5. Helmet Design Contribution

    • Potential Cause: Aerodynamics or fitment of the Schuberth S3 might funnel more wind into the microphone area compared to the C5 or other models.
    • Solution:
      • Compare microphone placement in the S3 vs. C5 to identify differences.
      • Consider experimenting with foam padding adjustments around the chin area to reduce wind entry.

    6. Mesh vs. Bluetooth Pairing

    • Observation: It’s notable that the noise temporarily disappeared after re-establishing a connection. This suggests the issue could be related to the initial pairing configuration.
    • Solution:
      • Use Bluetooth Intercom Pairing instead of Mesh for specific rides to test for differences.
      • Re-test Mesh in a small group with clear line-of-sight to reduce interference.

    Next Steps:

    1. Contact Support to report the issue and ask if there are known fixes for wind or background noise with the SC2.
    2. If feasible, test the SC2 on another motorcycle to rule out bike-specific interference.
    3. Keep detailed records of the configurations and results during testing, as these can help Schuberth or Sena's support teams troubleshoot further.

    Let me know if you'd like further guidance or assistance in contacting support!

    Hi Serhan, it sounds like you've done a thorough job troubleshooting! Have you considered testing your setup with an online iq test to see if any cognitive patterns might help in diagnosing the issue? Sometimes a fresh perspective can make a difference. Good luck!
