I worked just fine but it was hard to tell what it would have done if the camera had been heavier. Sound is very very good. They dont sound nearly as good as the $100+ aftershokz, but cost a lot less and build quality is good. However, recent conditions (Nintendo Switch portable gaming, Pandemic conference calls) put me in the market for some lightweight audio output. Otherwise glad I bought them. Lucky I have low standards and money to burn i guess. It is an easy assembly and nice sturdy product. Second issue - lack of dual Bluetooth connectivity. It was a gift The sound quality is good, the wire is extremely long as usual and the volume/mic control both work normally.
