Buyer: Hello, is the theatre system still available?
Seller: It is still available. Do you have any questions about it?
Buyer: Yes, has it been used?
Seller: My son hooked it up long enough to see if it worked. It works alright. My ears are still hearing the beats.
Seller: It is still available. Do you have any questions about it?
