For anyone who’s ever been kept awake by a snoring roommate, city traffic, or just the general hum of life, the SoundOff Sleep Earbuds might sound familiar. These little devices are built to focus on masking noise with pink noise for a quieter experience. They’re not your typical earbuds - no music streaming or phone calls here. Instead, they focus on masking unwanted sounds with something called pink noise. Curious about what makes them tick? This article digs into the specs of the SoundOff Sleep Earbuds, breaking down what they’re made of, how they work, and what users can expect.

What’s Inside the Box?

When someone picks up a pair of SoundOff Sleep Earbuds, they’re not just getting the earbuds themselves. The package comes with a few key pieces that make the whole experience work. Here’s what’s included:

1. The Earbuds: Two small earbuds, each with a flexible hoop that sits over the ear.

2. Charging Case: A compact case that doubles as a charger and storage unit.

3. Memory Foam Tips: A set of soft foam tips that fit into the ear canal (more on sizes later).

4. USB Charging Cable: A standard cable to power up the case.

5. Manual: A quick guide to get started, though it’s pretty straightforward.

It’s a no-frills setup, everything’s there to keep the earbuds running and comfortable, without extra bells and whistles.

The Charging Case Breakdown

The charging case isn’t just a holder, it’s a big part of how these earbuds stay practical. It’s small enough to toss in a bag, with a simple design that snaps shut. Inside, it’s got spots for each earbud to sit and charge via metal pins. The case itself uses a USB port on the back for power, and it’s built to keep the earbuds juiced up for days if needed.

Design and Build Specs

The SoundOff Sleep Earbuds are all about keeping things simple and comfy. They’re not bulky over-ear headphones or flashy tech gadgets, they’re tiny, lightweight, and made to fit in the ear without much fuss. Let’s unpack the details.

Size and Shape

These earbuds are designed to be some of the smallest in-ear options out there. They sit flush against the ear, with no parts sticking out that might dig into a pillow. Each one has a flexible hoop that hooks over the top of the ear, keeping it in place even if someone rolls around at night. The body of the earbud is coated in a soft, rubbery material, not hard plastic, so it’s gentle on the skin.

Materials Used

The earbuds themselves are made with a mix of lightweight plastics and that soft outer layer. The real standout, though, is the memory foam tips. These aren’t your average silicone buds, they’re crafted from a foam that softens with body heat, molding to the shape of the ear canal. That’s the passive noise-blocking part of the equation, and it’s what makes them feel snug without being intrusive.

Foam Tip Options

The foam tips come in a couple of sizes, typically small and medium, to fit different ears. They’re squishy, about 30 times softer than silicone according to the makers, and they’re meant to stay comfy even after hours of use. If they wear out, extra sets can be ordered separately.

How They Handle Noise

The whole point of these earbuds is to deal with noise, and they tackle it in two ways: active and passive masking. Here’s how that shakes out in the specs.

Active Noise Masking with Pink Noise

Instead of canceling noise like some fancy headphones, these earbuds play a steady sound to cover it up. That sound is pink noise, which is a bit different from the white noise people might know. It’s got a softer, more natural tone, like rainfall or wind through trees, and plays over lower frequencies such as snoring sounds. The pink noise comes from a chip built into each earbud, and there’s no need for a phone or app to make it work. Users can pick from eight volume levels, controlled right on the earbud, to dial it in just right.

Passive Noise Blocking

The memory foam tips do the heavy lifting here. By forming a seal in the ear canal, they block out a chunk of outside sound, up to 29 decibels, based on the noise reduction rating (NRR). That’s enough to muffle things like traffic or a chatty neighbor, though really loud noises might still sneak through faintly. Together with the pink noise, it’s a one-two punch to keep distractions at bay.

Noise Masking vs. Noise Canceling

For anyone wondering how this stacks up to noise-canceling tech, it’s a different approach. Noise-canceling uses electronics to counteract sound waves, but it doesn’t always get rid of everything, some noise can still creep in quieter. Masking, on the other hand, just drowns it out with pink noise so the brain doesn’t register the disruption. It’s simpler, and for these earbuds, it’s all built in without extra tech complications.

Power and Battery Life

Nobody wants earbuds that die halfway through the night, so let’s talk about how these stay powered up.

Battery Specs

Each earbud has a tiny battery that lasts up to 16 hours on a single charge, depending on the volume setting, lower levels stretch it further. That’s more than enough for a full night, even if someone’s a long sleeper. The charging case holds enough juice for about 168 hours total, or roughly seven nights, before it needs a recharge via USB.

Charging Process

Pop the earbuds into the case, and they connect to small pins that transfer power. The case itself takes a couple of hours to fully charge with the included cable. There’s no wireless charging option, but the setup is straightforward, just plug it in and forget it until it’s ready.

On/Off Controls

Each earbud has its own power switch, so they only run when needed. Turn them on, and the pink noise starts playing; turn them off, and they’re silent. It’s a manual process, no auto-shutoff or sensors here, but it keeps things simple and saves battery when they’re not in use.

Comfort and Fit

Comfort’s a big deal when something’s in your ear all night, and these earbuds are built with that in mind.

Flexible Ear Hoop

That little hoop over the ear? It’s not rigid, it bends to match the ear’s shape. It’s there to stop the earbud from falling out, especially for people who move a lot in their sleep. The flexibility means it doesn’t press hard or feel like a clamp, which is a plus for side sleepers.

Lightweight Design

At just a few grams each, these earbuds don’t weigh the ear down. They’re light enough that most folks won’t notice them after a while, which is key for something meant to be worn for hours. The small size helps too, no bulky parts to rub against a pillow.

Side Sleeping Compatibility

Side sleepers often struggle with earbuds, but the flush design and soft materials here make it less of an issue. The foam tips cushion the fit, and the hoop keeps things stable without adding pressure. It’s not perfect for everyone, some might still feel a slight nudge, but it’s a solid effort for a tricky sleep position.

Tech Features (Or Lack Thereof)

Unlike a lot of modern gadgets, these earbuds skip the high-tech extras. Here’s what that means in practice.

No Bluetooth or App

There’s no wireless connection here, no Bluetooth, no app to fiddle with. That’s intentional. The earbuds run standalone, playing pink noise straight from an internal chip. For some, that’s a relief, no pairing hassles or phone dependency. It also means no electromagnetic frequency (EMF) emissions, which might matter to folks worried about that kind of thing.

Manual Controls

Everything’s handled on the earbuds themselves. Each one has buttons for power and volume, eight settings to pick from. It’s basic but functional, and it keeps the user in charge without needing a screen or extra device.

Travel-Friendly Design

The charging case doubles as a travel holder, and the whole package is compact—easy to slip into a pocket or carry-on. With a week’s worth of backup power, it’s handy for trips without constant recharging. Plus, no app means no stress about Wi-Fi or phone battery dying on the road.

Pricing and Options

The SoundOff Sleep Earbuds come in a couple of buying choices, depending on what someone needs.

Single Pair Cost

A single set runs at $129.95 USD, down from a listed $179.95 USD. It’s a one-time purchase with everything included - earbuds, case, tips, and cable.

Two-Pack Deal

For couples or folks who want a spare, there’s a two-pack option. It’s priced at $219.95 USD (originally $359.90 USD), so it’s a bit cheaper per pair. Same specs, just doubled up.

Trial and Shipping

They come with a 30-day return window if they don’t work out, and shipping’s free. It’s a low-pressure way to test them without committing long-term.

Recognition and Background

The earbuds have picked up some nods from big names, which says something about their rep. They’ve been tagged as “Best Noise-Masking Sleep Headphones” by CNET, “Best for Snoring” by the Sleep Foundation, and similar titles from Rolling Stone, Travel + Leisure, and Yahoo Life in 2025. That’s not part of the specs, but it’s worth noting they’ve caught attention for what they do.
