I have a pair of the original Dash model from launch. The right ear bud has had a crack in it for over a year now, the bluetooth only works correctly indoors and they're over 3 years old now but they still work correctly and I still wear them to the gym 4 times a week. When I realized late last year that comply discontinued their foam tips, and Bragi was out of stock of almost everything on their website, I bought 6 pairs of extra foam tips from Best Buy on clearance for 50% off.
With the foam tips, they were basically the perfect wireless earbuds for me aside from the bluetooth flaws. The foam tips made them block outside noise as well as ear plugs do, and they were also a snug fit so I didn't need to worry about them falling out of my ears when using a decline bench. I did occasionally toggle on the audio transparency feature as well. This actually covers the two reasons I never upgraded to AirPods when they came out - EarPods only stay in well when your head is fully upright, (assuming AirPods behave similarly) and they don't block outside noise much.
It's a shame to see Bragi couldn't stay in the market, since I did like their product. That makes 2 tech products I've supported that have drowned out of the market by competitors which lack features I want. (The other being Pebble, which I'm still wearing one of their watches for the 10 day battery life and always-on screen. There are other companies that got some of the features right, like Amazbit, but none have the same app / watch face selection while also having good battery life.)
I think there are a couple of earbud style competitors to Bragi's Dash around still, so when my backlog of foam tips run out I guess I'll jump ship to whatever company makes the most comparable earbuds at that time. Right now Sennheiser seems to have something comparable to the dash, although their design plasters their logo over a metallic surface so it's not as subtle as the solid color look of dash. RIP Bragi
