HTC One / Beats Earbud Conflict
Problem
I have been recently using my beats tour with my HTC One. It was working fine and then it stopped working. First I thought either my phone had a problem or the earphones. I thought of claiming my warranty but, before that I did following tests:

Plugged different earphones in my HTC One from Apple, Samsung and HTC. All worked fine.
Plugged my Beats earphone with iPhone, iPod and my computer. It was working fine too.

Analysis
Then I compared the connector of Beats earphone with others. I noticed a potential design flaw with both Beats connector and HTC One:

Beats earphone connector radius is slightly smaller than normal earphone connectors.
HTC One internal connector was pushed in more when plugging and unplugging earphone.
(I don't exactly know words to explain this but, this usually happens with electronics when using cheap materials).

Solution
As I am sure both HTC and Beats won't be accepting these facts. I recommend you to buy a short extender. I connected my extender to my HTC One and Beats earphone and it worked like expected.

I am not sure if we lose quality when using a cheaper extender.
