Do they sound like you wanted, at least? If they sound like the previous pair, it may change the way you want the transaction to be handled.
At this point I think it's best that I just get a quick refund and try another speaker company. I don't have a second pair of speakers so each time I return the M3's I'm without any speakers. This is getting very tiring. I'm not making any of this up. I'm just really fed up.
