I had and loved my minidisc player back in the earlie naughties. The remote was great, but there was no standardization and it became a single point of failure. If and when it broke, you’d have to get the specific control for your MD player.

It kind of lived on in spirit with in-line volume/call controls for wired headsets on the 4-conductor 2.5mm jack. Those were cool, and standardized.

We could have a return to that, with USB-C, but I don’t think it’d see much more than a niche adoption. Smartwatches and fitness trackers do it just as well, and once you know the layout, you can skip/pause without looking. Plus most cordless headphones/earbuds have integrated controls as well. Streaming at home you have voice controls, streaming in the car they are on the steering wheel or stereo.

The wired in-line remote is really only even applicable to the already niche community of users who refuse to adopt wireless. Considering most of those people are strict audiophiles, only something that has a quality integrated DAC would appeal to them. Thats a pretty specific product for a pretty small market. Not saying it wouldn’t be feasible, but it’d certainly not be cheap and simple.

Tactile feedback is great though. I’m totally with you there…not many watches have physical buttons that you can locate and activate completely unaided by vision.
