N=2 is a important milestone in any empirical data set. I’ve now successfully tried two “Galaxy compatible” headphones with volume buttons with my Nexus 5 and I can now say with confidence:
All “Galaxy compatible” headphones work with a Nexus 5. 😉
I’ve actually tried the following headphones:
- Samsung EHS64
- Sennheiser MM 30G
Both the call/mute and the volume buttons work.
