You need to forget about how much you paid for them. It could have been the best thing since sliced bread at that time but that has no bearing on what it is currently worth. Looking at ebay prices you may be able to get $50 for the pair. $50 is better than $0 and a pair of chips you don't want. Now if you have some usage for them and their value to you is higher than $50 you should just keep it and put them to use.
