After waiting a month, I am not pleased with the Legacy CIEMs. They did not create a good enough seal, and my $20 KZs and my $60 KZs sound way better anyways. In order to get a seal, I have to continually push and hold the CIEMs in place. Yes, I understand I can schedule to have a new set of impressions made... and then pay ridiculous shipping charges to an address that is "extremely difficult for UPS and DHL to enter", and then of course wait another month to have Linsoul make a second attempt at making CIEMs for me... but you know, if they couldn't make them right the first time, chances are the second set isn't going to turn out much better. Therefore, I cannot truly comment on the quality of the Legacy 3 because the CIEMs prevent me from making a good assessment. All I can say it this... save your $200, and don't waste it like I did trying to get a company several thousand miles away to make you custom anything. I asked to have the CIEMs replaced with some generic IEMs of a similar value. Was told a couple of times, customs cannot be returned. I guess that makes some sense, but certainly puts the entire gamble on the customer. So, don't waste your money and get burned on shoddy customs like I did.
