Thank you for viewing. This is a set of "SoundTech CM-1000 USB" and "SoundTech CM-1000". I am selling these because I no longer need them due to a change in environment. They were used for about 4 months and are in good working condition with no problems. However, since they are used items that have been in someone's possession, I cannot guarantee their operation.
