SONY WF-1000XM3 For sale as I no longer use them. The earphones themselves have no noticeable scratches. The charging case has the Sony lettering fading, and the brown (gold?) parts show some scratches. Operation has been confirmed, but there are the following issues: • Occasionally, but not every time, the right earphone emits a high-pitched screech sound. This can be fixed by shaking the earphone by hand. The other earphone has no issues. • The battery is weak. After charging, they can be used for 2-3 hours without problems, but using them for longer is likely difficult → This can be repaired 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.
