Review: Soundcore Sleep A30

There are many things that can disturb my sleep at night. A wife who snores. A screeching bird outside the window. Seagulls on the roof. A neighbour’s dog barking, making a racket both early and late.

However, sleeping with headphones or earbuds is out of the question; it simply becomes too uncomfortable at night. They are either too tight or too bulky, or both.

The Sleep A30 is Soundcore’s third generation of sleep earbuds, the first model with active noise cancellation (ANC). They do not replace the A20, but are sold alongside it. If you can manage without active noise cancellation, the A20 is a cheaper alternative.

As flat as a pancake

The first thing you notice is the shape. Unlike standard earbuds, the Sleep A30s don’t stick out of your ear. They’re almost completely flat, which is important when you’re lying on your side with your ear pressed against the pillow.

Weighing just 3 grams per earbud, I can barely feel them in my ears. The Soundcore comes with an impressive selection of tips: four sizes in silicone and three in memory foam. It also comes with three sets of wings to adjust the fit. I chose the medium-sized silicone tips and matching wings, which are the ones that come with the earbuds when you take them out of the box.

Comfortable fit

The earbuds fit my ears perfectly straight away. They’re as light as a feather and don’t press against my ears. It stays that way for a long time after I’ve gone to bed. But during the night, my ears start to hurt. Especially when I’m lying on my side on the pillow. I toss and turn several times during the night and often end up with one ear facing downwards. With my firm Tempur pillow, this becomes a problem. The next night I try a standard down pillow, and it works much better. In other words, the experience will vary from person to person, depending on the pillow and sleeping position.

Triple noise cancellation

Soundcore claims to have a triple noise cancellation system. The first layer is passive insulation provided by the earbuds themselves. This is something they have in common with almost all other earbuds on the market. The second layer is active noise cancellation, which adapts to your ear canal. The third layer is noise masking, i.e. white noise, pink noise and similar sounds that drown out distracting noises in the room. The case even has a built-in microphone that picks up ambient sounds and adjusts the masking in real time. This feature works quite well; it’s impressive just how much technology has been packed into the A30.

The active noise cancellation works surprisingly well for such small earbuds. It dampens the constant hum of traffic outside, and the hum from the fridge or the running washing machine – both in the laundry room next door – is kept to a minimum. It isn’t as effective against sudden, high-frequency sounds such as snoring. In that case, it’s good to have the masking sounds.

Missing the vented ear tips

What I really liked about the A20 were the vented silicone ear tips, which prevented that ‘underwater feeling’ you get with a pair of tight silicone earbuds that rub against the inside of the ear canal. Even when lying still, swallowing movements will cause unwanted bass sounds to travel through the earbuds and into the eardrum.

The A30 only has closed-back ear tips. The reason for this is that active noise cancellation requires it. Otherwise, the out-of-phase sound can leak out of the ear and into the microphone, creating a feedback loop. This is the same reason why ANC doesn’t work on open-back headphones.

Sound library without a subscription

The Soundcore app offers a wide range of sounds. You’ll find everything from classic white noise to rain, waves, crackling fire and the sounds of an aeroplane cabin. In addition, there’s so-called AI brainwave sound – binaural beats that help the brain enter a calm state. You can even create your own soundscapes, and the A30 can recommend soundscapes based on the environment you’re in.

If, on the other hand, you prefer to fall asleep to podcasts, the Sleep A30 works just like ordinary Bluetooth earbuds. The sound is better than in the A20; among other things, I think the bass is better. But it’s still not the first choice for serious music listening. For that purpose, you should have a decent pair of music earbuds to hand.

Three battery modes

Soundcore claims that the battery life is 9 hours with ANC enabled. This is noticeably shorter than the 14 hours offered by the Sleep A20. You’ll soon find that the A30 runs out of power before you wake up.

But Soundcore has a trick up its sleeve here. You can switch to local audio and turn off ANC to maximise battery life. The A30 with local audio and ANC turned off actually gives you 16 hours, which is more than the A20 under certain conditions.

You can also leave ANC switched on but turn off the audio, or leave everything switched on fully. The former saves the most battery, the latter drains it the fastest. A smart solution that gives you control.

With the charging case, you get up to 45 hours in total, so you don’t need to charge the case as often. But I would have liked to see wireless charging on a product that costs this much and is intended to be kept on your bedside table.

New research: Is silence better than white noise?

Finally, we must make a reservation regarding white noise. A new study published in the journal *Sleep* in February 2026 shows that white noise can reduce deep sleep by up to 23 minutes per night. The researchers found that passive earplugs – i.e. ordinary foam earplugs without sound – were significantly more effective than noise-masking sounds at protecting sleep quality.

My objection here is that research in controlled environments does not necessarily take all variables into account. Many people have a mild form of tinnitus that they are barely aware of. In completely quiet surroundings, such phantom sounds suddenly become audible. In such cases, noise masking with the sound of waves or distant thunder can actually help you fall asleep. The ‘perfect’ sleep, according to the researchers, isn’t necessarily the most practical for everyone.

I can well imagine that the Sleep A30 works brilliantly for tinnitus sufferers, precisely because the masking sounds drown out the irritating ringing in the ears. As a bonus, it also has noise reduction, so you can choose for yourself.

About sleep tracking

The Sleep A30 can track your sleep and provide data on sleep duration, sleep stages and snoring frequency. In practice, the data didn’t always match my own experience. On several nights, the app reported that I was sleeping more deeply than I felt I was. If you have dedicated sleep tracking on your smartwatch, it may be more accurate.

Sleep A20 or A30?

After several nights of testing, I’ve come to a surprising conclusion: I actually prefer the more affordable Sleep A20. It’s cheaper, has better battery life, and with the ventilated ear tips, I get a more comfortable sleep experience without that underwater feeling that closed-ear earbuds give.

The Sleep A30 is best for those who need ANC to block out constant low-frequency noise – traffic, ventilation systems, air travel. If you live in a quiet area and just need to mask your partner’s snoring, I think the A20 is the smarter buy.

Conclusion

The Soundcore Sleep A30 is a well-designed product for those who want active noise cancellation in their sleep earbuds. The noise cancellation works well against low-frequency noise such as traffic and fridges, and various battery modes give you control over power consumption.

The lack of vented ear tips makes them feel more enclosed in the ears than their predecessor, the A20. After several nights of testing, I actually prefer the A20. They are cheaper, have better battery life, and the vented tips provide a more comfortable sleeping experience.

If you need ANC to block out constant low-frequency noise, the A30 is a good choice. For others, the A20 may still be the smartest buy.
