Would be nice if I didn't need to download a 2.1 MiB image to view this page. Could probably keep the visual appeal here without the bloat by simply switching to JPEG.

Edit:

Also I'm having a hard time understanding your value proposition. Are these doing some active noise canceling, or are they just simply a bluetooth headset with semi-decent passive noise suppression?

Also, why would I want these to be connected to my smartphone while I'm sleeping? Am I going to be woken up by every text/e-mail?

Point being, when I read the copy at the top of your page I instantly think that your product is going to make my ability to sleep worse rather than better.

Edit 2:

The rest of the page clears up some of my questions, but I think you'd have a lower bounce rate if you worked on the headline copy a bit more.
