I hope you don't get a bad pair as I have been trying to get mine replaced since July. It took till August to get a reply from Massdrop. There is no way to contact Havi. I sent snail mail to the address in Jersey on the box and still have not got a response. Finally got a response from Massdrop Aug 5 and took till Sept 5 to get a resolution working. They got my defective set on Sept 14 and it took two emails and messages on Twitter and Facebook till I got a response today Sept. 27. I would not have a problem if I could contact Havi. You can't go to the website that is on the box. I don't understand how a company can produce something and not support it. If you can find there website I would like to know it as I would like to bypass Massdrop as they suck at customer service as far as returns. Yes I'm pissed. So take my experience with a grain of salt.
