Play and pause don't work properly with bluetooth headphones (Mac)
Heyho i have the same problem with the same Headset.
I found this in a Spotify forum:
There is a fix everyone!
Just go to Edit -&gt; preferences -&lt; Display options and disable &quot;Show desktop overlay when using media keys&quot;
This fixed my issue atleast

For me it did not help...even worse... i'm more confused. After disable this Options the browser works, but the Ingam-Spund mutes.
