How comfortable are CozyPhones to sleep with?

Even side sleepers find CozyPhones to be comfortable enough to sleep with That's why we call them "CozyPhones" after all.  The speakers are less than 1/8" thick and covered with foam and then tucked inside the headband so as not to create extra pressure on your ears. The width of the speaker (slightly larger than a quarter) also helps to create a comfortable fit for hours of comfortable sleep or relaxation.
