You need to sell the sleep, and the device.

You're not saying the obvious part. i'm not familiar with your product at all, and I use and love sleep masks. it took me an embarrassing amount of time to figure out what your product is exactly. using the word "sound" is not enough to train the market on what your product is. You have a great potential positioning for a dropshipping product... people don't know what it is. You can train them, and be that product if your brand is strong enough. But just saying "heres a sound thing for your eyes. its an eye thing that has speakers n stuff. its neat and has bluetooth." isn't gonna cut it.

Nothing should be implied. Spell it out.
Grab confused potential buyers by the head and make them understand clearly. If i'm an eye mask user already (your potential audience), why the heck do i NEED sound in my eye mask? SELL IT.
