Electronic Technical Report issued on: 07/07/2026
⚠️ SAFETY WARNING / FIRE HAZARD. This device contains lithium batteries integrated into the temples. Never attempt to disassemble, puncture, or bend the glasses frame: puncturing lithium cells can cause short circuits, flames, or explosions. For any internal hardware intervention, exclusively contact an authorized service center. ReeFix provides this diagnosis for informational purposes only.
If you own Ray-Ban Meta Wayfarer (Gen 2) smart glasses or the previous Ray-Ban Stories Wayfarer (often generically referred to as Ray-Ban Wayfarer 2 smart) and are experiencing issues with call audio, this guide will help you identify and resolve the problem.
Probability: 50%
Why it happens: The problem occurs when the smartphone struggles to switch from the Bluetooth A2DP profile (used for music/video) to the HFP profile (necessary for two-way calls). The phone's operating system, to avoid interrupting the call, diverts the audio to its internal speaker. This is often due to a corrupted Bluetooth cache or suboptimal interaction between the Meta View app and your smartphone's Bluetooth stack.
Key signs:
Quick checks (do it yourself):
Probability: 30%
Why it happens: The glasses are equipped with a proximity sensor located inside the right temple that detects if they are being worn. If this sensor is dirty, obstructed, or malfunctioning, the firmware interprets that the glasses are not on your face. For privacy reasons, the system deactivates the HFP profile for calls, forcing the audio to the smartphone. An accumulation of sebum, makeup, or dust is a common cause. In case of a hardware failure of the sensor, repair or out-of-warranty replacement through official assistance can have an estimated cost between 100€ and 150€, making the intervention cost-effective compared to buying a new pair (around 329€-400€).
If you also notice that the photo and video capture button stops responding, the cause is almost certainly the wear detection sensor not correctly detecting contact with the face. Many users temporarily resolve this by deactivating the 'Wear Detection' function directly from the Meta View app settings.

Tools needed for cleaning:
Probability: 15%
Why it happens: This situation often occurs when other Bluetooth devices connected to your smartphone (e.g., smartwatch, car infotainment systems, headphones) try to take control of the HFP profile for calls. The smartphone system may have difficulty establishing a clear priority, preventing the glasses from correctly activating the two-way audio channel.

Considering the probabilities:
If the signs match CAUSE A (50%): Start with the quick checks (Bluetooth restart, unpairing/re-pairing, app reinstallation). These are the most common solutions and you can do them yourself. If the problem persists, try testing with another smartphone. If it works with the second smartphone, the problem is almost certainly with your phone and you might need to consider a network or factory reset of the phone itself. If the problem persists even with another smartphone, move to point 2.
If the signs match CAUSE B (30%): Cleaning the sensor on the right temple is an excellent first step you can do yourself. Use the recommended products gently. If after cleaning and temporary deactivation of wear detection the problem persists, a hardware failure of the sensor is likely.
If the signs match CAUSE C (15%): Try isolating the glasses by deactivating other Bluetooth devices. This is a simple and quick check.
Operational decision: First perform the quick checks for Cause A (the most probable, 50%) and the cleaning/deactivation for Cause B (30%). If you use multiple devices simultaneously, also perform the tests for Cause C (15%). If after all these DIY attempts the problem persists, contact a specialized technician for an in-depth hardware diagnosis (e.g., FPC flat cable or sensor check). Device replacement is recommended only if the technician declares the repair uneconomical or impossible.
