This is the AfterShokz (now Shokz) OpenMove bone conduction headphones. I am selling them due to a replacement. *Please be sure to check the following condition and agree before purchasing. ■ Product Condition (Reason for being defective) Microphone function: The condition is poor, and my voice is difficult to reach the other party, or it doesn't come through. Not suitable for calls. Charging port: The protective rubber cover is missing. There is no problem with use (charging) itself, but waterproof performance cannot be guaranteed. Appearance: There are some peeling and scratches on the surface due to use. Audio playback: Music, video viewing, and radio listening can be heard without any problems. ■ Recommended for those who: Do not make calls and want to get them cheaply for "music/radio playback only" during running or work. Want to try bone conduction headphones. ■ Contents Main unit only (Please prepare your own USB-C charging cable) ■ About shipping After disinfecting and cleaning, I will pack it with cushioning material and ship it. I have set the price low considering the condition. For those who can utilize it for parts or playback only, thank you.
