HoMedics SoundSpa vs. Yogasleep Hushh

The HoMedics SoundSpa and the Yogasleep Hushh both cost under $30, both produce white noise, and both work. But they are built for different situations.

The HoMedics SoundSpa is a classic plug-in bedside machine. It stays in the nursery, runs on AC power, offers six sounds, and has a timer. It is one of the best-selling budget sound machines in the US precisely because it does everything most parents need for home use without any complexity.

The Yogasleep Hushh is built for portability first. It clips onto a stroller, fits in a pocket, charges via USB-C, and has a child lock that keeps curious hands from changing the settings. It gives up timer functionality and most of its sound variety in exchange for being genuinely portable.

If you are only buying one machine and your baby sleeps exclusively at home, the SoundSpa is the smarter choice at a lower price. If you travel or need a machine that goes where you go, the Hushh earns its price premium.

For context on what volume and distance guidelines apply to both machines, see our guide on sound machine volume for babies.

The SoundSpa includes white noise, thunder, ocean, rain, brook, and summer night — six distinct tracks. This matters in the early weeks when you may be experimenting to find which sound settles your baby most reliably. Some babies respond strongly to one sound type and ignore others; having six options increases the chance of finding a good fit quickly.

The Hushh offers white noise, ocean, and gentle surf. Three sounds is a real limitation for initial experimentation, but most families settle on one or two sounds within the first few weeks and stop switching. If you already know your baby responds to white noise or ocean-type sounds, the Hushh's smaller library is not a problem in practice.

Both machines play looped recordings rather than continuous generated noise. At this price point, that is standard. The Hushh's loops tend to be slightly smoother, though both are generally fine — most babies are not bothered by the loop seam.

This is where the two machines diverge most meaningfully for everyday use.

The SoundSpa runs on AC power via its included adapter — which is ideal for a fixed nursery setup. Plug it in once and forget about it. It also accepts 4 AA batteries for portable use, but this is a real limitation: four AAs running overnight drain in two to four nights, adding ongoing cost and the inconvenience of battery replacement. The battery option is best for occasional use during travel or power outages, not as a regular system.

The Hushh has a built-in rechargeable battery that charges via USB-C. On low volume it runs for roughly 8–10 hours — enough for a full night's sleep. On medium to high volume, expect 5–7 hours. Charge it during the day and it is ready by bedtime. This is a genuinely better portable solution than any machine that depends on disposable batteries.

If your baby's room has a nearby outlet and the machine stays on the nightstand, the SoundSpa's AC power is an advantage — you never think about charging. If the machine moves around, the Hushh's rechargeable battery is significantly more practical.

The SoundSpa includes a timer with three settings: 15, 30, or 60 minutes. This is a useful feature that the Hushh completely lacks.

For naps, a timer means you do not have to remember to turn the machine off after your baby falls asleep — it handles itself. For bedtime routines, a 15 or 30-minute timer can serve as an automatic wind-down signal. For parents who prefer not to run sound all night, it provides an easy off switch.

That said, many sleep consultants recommend running white noise for the entire sleep period rather than using a timer — continuous sound does a better job of masking the intermittent household sounds that can cause early wake-ups. Whether you use a timer is a personal and philosophical preference, but having the option is useful.

The Hushh has no timer. You power it on, set the volume, and it runs until the battery dies or you turn it off manually.

The Hushh's clip design sets it apart from every other machine in this price range. The clip attaches to a stroller frame, carrier strap, car seat handle, or diaper bag. The machine sits a few inches from your baby's ear rather than across the room — which actually helps with volume management, since you can run it quieter and still have it be effective.

For families who travel — weekend trips, flying, staying at grandparents' houses, or time at daycare — a machine that clips on and charges from a USB port is meaningfully more convenient than one that needs an adapter and batteries. Hotels and vacation rentals always have USB ports. Not all have convenient outlets near the crib.

The SoundSpa is compact enough to pack in a bag, but it requires either its AC adapter or a fresh set of batteries. That is workable, not ideal.

If your baby is past the crib stage and naps in a stroller or on the go, the Hushh's portability is not just a convenience — it is the primary reason to buy it.

The HoMedics SoundSpa (~$20–$25) is widely available at Target, Walmart, Amazon, and Walgreens. It is one of the most stocked sound machines in physical retail — easy to find last-minute if you need it quickly. The AC-powered version is the one to buy; skip any variant advertised as "battery only" unless you specifically need battery power.

The Yogasleep Hushh (~$25–$30) is available at Amazon, Target, Buy Buy Baby, and Yogasleep's own website. If you plan to use it for travel, buy it a few days before your trip so you can test it and make sure it is fully charged before you need it. The clip is included in the box.

Both machines are returnable at major retailers if they do not work for your baby.

Both machines are safe at reasonable settings. The key guidelines apply regardless of which machine you choose:

• Keep the machine at least 7 feet from your baby's head, or as far away as the room allows.
• Target below 50 dB at your baby's ear level. A free decibel meter app on your phone is sufficient to check.
• If you can have a normal conversation without raising your voice when the machine is running, the volume is probably fine.
• Avoid placing either machine directly inside the crib or attached to a crib rail at ear level.

The Hushh's clip feature deserves a specific note here: when clipped to a stroller, it sits closer to your baby than a room-based machine would. Run it at a noticeably lower volume when clipped nearby than you would when placing it across a room.

Neither machine has a volume limiter, so the responsibility for safe volume sits with the parent setting it. Start lower than you think you need and adjust up only if ambient noise is actively disrupting sleep.

Neither machine is objectively better — they are built for different use cases.

HoMedics SoundSpa is the right choice if you want a reliable, plug-in home machine with more sounds and a timer at the lowest price. It does the job without any frills.

Yogasleep Hushh is the right choice if portability matters — travel, stroller naps, or life with a baby that rarely sleeps in one place. The rechargeable battery and clip design justify the small price premium for families on the move.

If you are unsure, start with the SoundSpa for home use. If you find yourself wishing you had something portable after a few weeks, add a Hushh for travel. Many families end up with both.
