I don't understand all the venom toward Hifiman. Any time I've had a question, suggestion, or dealing with the company I get a prompt message returned and they're quite friendly.
I think it's great that they're offering an upgrade for the HE1000. Sennheiser is not for the HD800 to HD800s, yet there doesn't seem to be a groundswell of complaining about Sennheiser. I own the HD800. I'm not mad at Sennheiser for making a better product and making me purchase a new one if I want it. I'd upgrade if the path were there, but I don't now see Sennheiser as practicing poor business or not caring bout me. They make good products. If I want the new HD800s, I have the option of buying.
If you judge the QC of the HE1000 as bad, return them or replace them and move on. Buy a headphone that better meets your standards.
Complaints about business strategy? What concern of that is mine? If I like the product I buy the product. If I don't like the product, or I think it's a bad value, I pass. If there's a product I'd rather have, I sell the product I own on eBay and I buy the one I want. Why is it the manufacturer that must bend to my personal choice? It would seem the buyer has the power-- in their wallet. If people stop buying the HE-1000, Hifiman will lower the price, discontinue them, or change them to address any issues.
I haven't auditioned the Focal Utopia, perhaps it's a better headphone. I personally think the HE1000 is a masterpiece.
