SONY WF-1000XM3 Selling because I no longer use them. The earphones themselves have no noticeable scratches. The charging case has fading of the Sony logo, and the brown (gold?) part has some scratches. Functionality has been confirmed, but there are the following issues: • Occasionally, but not always, the right earphone emits a high-pitched screech sound. This can be fixed by shaking the earphone. The other earphone has no issues. • The battery is weak. After charging, they can be used for 2-3 hours without problems, but it's likely difficult to use them for longer than that. → This can be fixed by replacing the battery. Due to the above, I am selling these as junk. Are these suitable for someone looking for parts, someone good at repairs, or someone only looking for the left earphone or charging case? I will clean them with a disinfectant wipe and package them. ※ There is no outer box.
