If you are in the US, go to a physical retail Microsoft Store and try your
headphones on their demos. Bring your Surface. They can exchange it if it is
hardware, but if it is out of warranty, it will most likely cost $650 US. If you
are not in the US, you might exchange online, but you will get a refurb and it
is unknown if it will be as good as what you have now.
