For $22 BlueAnt’s Ribbon is a great choice for keeping your favorite wired headphones working in a bluetooth world.
Long battery life, big buttons, and a built-in mic for hands-free operation make the Ribbon a pretty handy device. Streaming with my iPhone is just fine too. I’m using one in my VW Van, as its stereo pre-dates bluetooth, and it is great for keeping headphones working in any motorcycle helmet without its own audio system.
The built-in mic works to access Siri, if you want to talk to Siri. Alexa plays podcasts when I ask.
