I really wanted to like these. The sound quality for Calm Sleep Stories is just not there. Now the right ear bud is not charging to full. They are comfortable to sleep in for this side sleeper.
For years I have been waking early (3-4 AM) and unable to go back to sleep. I now sleep 7-8 hours through the night. Fits perfectly with preinstalled medium tips, never fall out, and I hardly notice them as a side sleeper. Blocks out almost all sound, brown noise in sleep mode works for me. Sound quality for music is mediocre, but that is not the purpose.
The sleepbuds A20 are the most Amazing sleepbuds!! I highly recommend! They mask sounds and snoring Perfectly!! The battery life is incredibly long. The sound library is very big with ability to layer sounds. The customer service is the Best there is and they Always respond quickly. These sleep buds are life changing.
