About one week after receiving them, the sound got very faint on one side, but that cleared up after about a week and has been fine since.

Sound seems good.

Poor sound you better invest your money either in original Apple headphones or ones with better reviews...

The sound is good and I'm using them while walking and sleeping, but wouldn't try them for exercising because they'd likely come out of my ears

These are not headphones for folks looking for the absolute best quality sound, but if, like me, you need comfortable ear buds for sleeping in - even on your side - these are perfect.
