A:Answer The Sleepbuds II is way better. The Sleepbuds II are flatter and more oval-shaped, making them even more comfortable inside your ears. Probably due to the better fitment, passive noise isolation has been significantly improved. Also, when you rub your head on the pillow while lying sideways, there is no more rubbing noise.
The charging mechanism has also been improved. The charging pins and the magnet are no longer on the same row but separated into two, making it easier and faster to position the Sleepbuds correctly when putting them into the charging case. Due to the redesign, I don't think the magnet is going to eventually fall out like they did with the original Sleepbuds.
