This is the AfterShokz AS650. I've only used it a few times since I bought it. I'm selling it to declutter. It powers on. It can be charged. I've confirmed Bluetooth connectivity. Sound comes out. It works normally. The accessories are as shown in the photos. Regarding the condition of the product and its usage, I ask that there be no claims and no returns. Self-introduction: I am a non-smoker and do not have any pets. I have a dust mite allergy, so I pay more attention to cleanliness in terms of cleaning and laundry than the average person.
