I would say that Bobby once he has used the CD player for 3 months without a complaint he may not be able to return it. Only if there is a 3 month warranty, then he may be able to return it/replace it or if he has an extended warranty, otherwise he is probably out of luck.
Under these conditions, Bobby has accepted the CD player, because it was the buyer's (Bobby's) responsibility to inform the seller (Sammy) about the defect. Since he bought it regardless and used it for quite some time despite having to face the defect for quite some time, it fully belongs to him. In other words, he has already accepted the CD player and can't ask for a return of funds from Sammy Electronics.
