      • ★★★★★

        Game-changer! I used to toss and turn for hours, now out like a light. Wife says I’m easier to live with.

      • ★★★★★

        Instant stress-killer! Campfire sound and dim red light calm me instantly. Portable, great for hotels. 5 stars.

        Emily Carter

      • ★★★★★

        Turned this on, girlfriend relaxed within minutes. She loves the ocean + campfire combo. Now, she ‘accidentally’ stays over every night.

        Carlos Ramirez

      • ★★★★★

        I create the perfect vibe for dates with this. Custom sounds, lights—everyone loves it. Helps me sleep and be ready for anything.

        Ali Rahman

      • ★★★★★

        My wife and I argue every night over which sounds to mix. Luckily, we both sleep like babies either way.

        Lucas Bennett

      • ★★★★★

        Was worried the light could be too bright, but it has 30 brightness levels! I set it to lowest and love how soft it is.

        Bought for my husband because he snores like a train. Lifesaver for our marriage!

        The Problem with Modern Sound Machines

        • 📱 Dependence on Apps

          Need to change the sound?
          Grab your phone. Open the app. Tap through menus.

          And don't get us started on paid subscriptions.

        • ❌ Zero Customization

          One sound. Every night.
          No wonder your brain tunes it out and your thought loops start over.


          You deserve better than looped white noise.

        • 🔌 Constant Charging

          Hard to move, annoying to unplug, and can't actually take it around with you.


          So much for “portable.”

          Frequently Asked Questions

          Are there any hidden subscriptions?

          No! It's a one-time purchase with no hidden fees or subscriptions. Once you buy it, you own it.

          I’ve tried other sound machines. Why is this different?

          Most machines just offer basic white noise. The Afterglow gives you total control — mix and layer 8 natural sounds and set your ideal lighting. It’s the only sound machine made for couples for full personalization.

          What makes this better than leaving the TV on or phone apps?

          TV and phone screens emit blue light and radiation, proven to lower melatonin production. The Afterglow is completely screen and app-free.

          Does it really help with overthinking and anxiety?

          Yes, the Afterglow uses scientifically supported soundscapes that blend pink, brown, and white noise using calming natural elements.

          These soundscapes allow the mind to shift away from spirals and into a relaxed state.

          Do I need Internet or Wi-Fi to use it?

          Nope! All the sounds come pre-built into our noise machine.

          Do I need batteries?

          No, it has a built-in rechargeable battery, so you don’t need to buy disposable batteries. You can also plug it in for continuous power, perfect on the go.

          Can I turn the lights off completely?

          Yes! You can dim the lights or turn them off completely by turning or pushing the orange button.

          What if I don't like it?

          No worries — you’re covered by our 30-night guarantee. Try it risk-free, and if it’s not for you, send it back for a full refund.

          A Word From The Founder
