They’ve been my go to for headphones & speakers for a while, but my last few purchases of different models all ended up getting returned due to the same connectivity issues. Sitting at home, the headphones are fine, but when I’m out for a walk, they experience some sort of interference that causes the music to skip/stutter. I still have an old, long discontinued, pair of Anker earbuds, and when I go for the same walk with those, there’s zero connectivity issues.
