The comfort is good they are great for long listening intervals. I recommend putting your fingers underneath the foam and pushing the plastic disc with your thumb. however, for a two year old they are not the most appropriate. I ordered this earphone set mainly because it was one of the few products where the charging case was also a power bank, which also makes it great for light traveling. My little one wore these for TWO DAYS. Having Apple CarPlay is bonus enough, but the quality of the sound that this little unit puts out is nothing short of EXCELLENT! Theyll be ideal to wear once the weather improves. Ive had this thing for several months and now the 700s stick to the PC like glue. These are my endgame. As nice as it is, its so over engineered and not at all necessary.
