A:AnswerI have yet to drain the battery to the point of powering off and have used 4-5 hours at a time. I believe the manufacturer states about 5-6 hours.
A:AnswerI've tried several different ear tips with mine, and more than a few will work, but I think the best come from Comply, which now makes an ear tip specifically for the Galaxy Buds:

Not sure if Best Buy carries them (they ought to!).
Best Buy does carry these, though:

These improve sound quality considerably, but one possible issue is that I've sometimes had one or both eartips get stuck in my ears when removing the earbuds. Doesn't always happen.
Hope this helps!
A:AnswerYes the earbuds are still compatible. If you get these earbuds, make sure to install the Galaxy Wearable app to connect and use them to their full value. Between the older Gear Icon X and Galaxy Buds, the Galaxy Buds deliver better sound and are slightly different in their eartips. The charging case is the largest difference, removing all buttons and the Galaxy Buds case has wireless charging as well.
