"Quiet, Restful Nights": This is an emotional benefit, selling the outcome (better sleep) rather than just the product.
"All-Night Comfort": Directly addresses a major concern for potential users—that the device will be uncomfortable and prevent sleep.
"Custom Fit": Makes the user feel the product is tailored to them, even though it's a standard, self-adjustable size.
"Easy to Use & Clean": Tackles two common objections: complexity and hassle.
