People have mentioned Mighty as a not-great alternative but I've had mine for over a year now and think it's great. I was an iPod Shuffle guy for years but Airpods + Mighty = no annoying cord. I don't know how you can say it's bad. Plus having unlimited access to Spotify's music instead of maintaining MP3s is way better.
If you're doing runs of an hour or more then you have to charge it after each run but that's not really a big deal once you get used to it. I've never had it die on me, granted my longest runs are 80-90 minutes, so maybe it would die on 2+ hour runs. but overall I recommend.
