I was going to open it and use it, but I gave up because I couldn't connect it properly. It's new and unused, an AudioComm ear speaker, ASP-206N. It's convenient for hearing the TV sound clearly up close, such as when watching TV with family. It also has a clear voice function. Although it's unused, it has been stored at home, so please refrain from purchasing if you are sensitive to this.
