Soundcore Sleep A20 vs Loop Quiet: Best Sleep Earbuds for Side Sleepers
Smart sleep earbuds with an app and an alarm, or $24.95 passive earplugs that never need charging? We compare the Soundcore Sleep A20 and Loop Quiet 2 for side sleepers, on comfort, noise blocking and value.
Side sleepers have the hardest time with sleep audio. Earbuds built for music dig into the pillow and your ear canal all night, and foam plugs fall out by 2 a.m. Two products solved this from opposite ends: the Soundcore Sleep A20 ($149.99), smart sleep earbuds with an app full of masking sounds, and the Loop Quiet 2 ($24.95), passive silicone earplugs that simply turn down the world.

Two opposite philosophies
These products barely belong in the same category, and that's exactly why the comparison is useful. The Soundcore Sleep A20 believes your ears should do something at night: play masking audio that covers the snoring, track your sleep with motion sensors, and wake you with a gentle built-in alarm. It's a tiny computer you sleep in. The Loop Quiet 2 believes your ears should do nothing at all — a shaped piece of flexible silicone that turns down the world's volume by up to 24 dB (SNR), with no battery, no app, nothing to fail at 3 a.m. The choice isn't which is "better"; it's whether you want a feature or a void.
The Sleep A20 wants to replace the noise with something nicer. The Loop Quiet 2 just wants the noise gone. Both are valid — but they're different jobs.

The Soundcore Sleep A20 in detail
The A20 launched in spring 2024 at $149.99 as Soundcore's dedicated sleep earbud. Each bud weighs just 3.2 grams with a low-profile housing that doesn't lever against the pillow, and the box includes six eartip sets — three sizes in breathable and sealed styles — so most ears get a comfortable, sealed fit.
Here's the surprise that matters most: the A20 has no active noise cancellation — there are no microphones at all. That's deliberate: ANC can create a feeling of pressure some people find uncomfortable during deep sleep, and microphones add bulk. Instead, the A20 pairs passive isolation from double-flange tips (up to 30 dB of high-frequency reduction, per Soundcore) with masking audio from the app: dozens of sounds — rain, white noise, ambient environments — mixable three at a time and playable offline from the buds themselves.
The smart features are genuinely useful. Motion sensors enable sleep tracking (position, movement, duration) in the Soundcore app, Smart Switch auto-engages sleep mode at bedtime, and a built-in personal alarm wakes you with gentle vibration followed by a low-volume tone — ideal if you share a bed. Battery life is a strength: up to 14 hours in sleep mode per charge, 10 hours in Bluetooth streaming mode, and up to 80 hours total with the USB-C case. For nightly use, charge the case every two to three weeks. They're rated IPX5, so sweat isn't an issue.
The honest caveats: reviewers are split on the passive isolation — Tom's Guide's review found it weak enough that light sleepers wouldn't get much relief, while other testers found the seal plus masking audio erased the outside world. Fit matters enormously, which is why the six tip sets exist: a bad seal means bad everything. The touch controls are fiddly, the app requires account registration, and at $149.99 these are not your daytime earbuds — they're single-purpose.
The Loop Quiet 2 in detail
The Loop Quiet 2 is almost aggressively simple. A pair of reusable silicone earplugs with an acoustic channel engineered for up to 24 dB (SNR) of noise reduction — Loop's second-strongest consumer rating, behind only the sleep-tuned Loop Dream at 27 dB. They come with four tip sizes (XS through L), a carry case, and sit nearly flush in the ear.
That's a genuine comfort advantage: a passive plug has no electronics housing to press into the pillow, so the Quiet 2 is about as close to "nothing in your ear" as a noise-blocking product gets. They're also certified hearing protection, reusable and easy to clean, and buying directly from Loop gets you a 100-night sleep trial plus a two-year warranty — unusually generous for a $25 product.
The trade-offs are honest ones. There's no masking audio, so you'll hear a muffled version of reality — snoring becomes a distant rumble rather than disappearing behind white noise. Some users report them loosening overnight if the tip size is wrong, so find your size before judging them. And 24 dB (SNR) won't rescue you from a truly thunderous snorer.

Side-sleeper comfort compared
This is the make-or-break test for both products, because roughly 60% of people sleep on their sides — and an earbud that hurts at 2 a.m. gets abandoned by 2:15. Here's the honest breakdown.
Loop Quiet 2: the comfort winner, and not by a little. Flexible silicone, no battery or circuit board inside, and a profile that sits flush with the ear means the pillow simply has nothing to press on. Long-term reviewers consistently report sleeping through the night with them in, including dedicated side sleepers. The four tip sizes matter here — a proper seal means the plug doesn't migrate when your ear deforms against the pillow. The only recurring complaint in extended reviews is warmth: after several hours, silicone can feel slightly warm and damp against the skin, a normal trait of any sealed plug.
Soundcore Sleep A20: genuinely comfortable for a powered earbud — even skeptical reviewers who expected them to fail as side and stomach sleepers reported keeping them in all night with only occasional repositioning. But "for an earbud" is doing work in that sentence: you're still pressing a 3.2g rigid object between your ear canal and a pillow for eight hours, and restless sleepers do feel them when rolling over. They also sit slightly prouder of the ear than the Loops.
The verdict on comfort: if side-sleeping comfort is your primary filter, the passive plug wins on physics. Electronics need space; silicone doesn't. The A20 is the best powered option for side sleepers we've seen, but the Quiet 2's flush fit is in a different league.
Noise blocking compared
Comfort is only half the job — the other half is actually silencing the night.
Passive blocking: on paper, the Loop Quiet 2's 24 dB (SNR) beats the A20's tip-only isolation. In practice, both depend on a good seal — and Tom's Guide's testing found the A20's passive isolation alone underwhelming for light sleepers, our most honest data point here. The A20's real blocking comes from its second act: masking audio. A steady rain or brown noise track at low volume covers the gaps passive isolation leaves — the irregular snore, the car door at 4 a.m. — in a way silence alone can't.
What you can't block: neither product helps with low-frequency vibration — bass from a party next door, a truck idling outside — because small in-ear devices can't touch those wavelengths without ANC, and neither has it. For one loud, irregular source like a chainsaw snorer, a white noise machine plus earplugs together will beat either product alone.
The alarm question: the A20 has a built-in gentle alarm that wakes only you — a genuine advantage for couples on different schedules. The Loops muffle everything equally, so a phone alarm across the room may or may not reach you; most users report still hearing it, but heavy sleepers shouldn't gamble. If you need a guaranteed wake-up without disturbing a partner, the A20 justifies its price on this feature alone.
Price and value
The price gap is worth stating plainly: the Soundcore Sleep A20 launched at $149.99 — six times the Loop Quiet 2's $24.95 — though in 2026 it's frequently discounted to around $100. The extra money buys masking audio, sleep tracking, a personal alarm, Bluetooth streaming and a charging case, versus a silicone plug that does one thing forever with no running costs. The Loop Dream at $49.95 sits between them: stronger blocking (27 dB SNR), still zero electronics. Over a year, the A20 costs roughly six Loops — or, put another way, one A20 costs the same as losing your Loops six times.
Our honest pick
For most side sleepers, buy the Loop Quiet 2. It's cheaper by an order of magnitude, more comfortable against the pillow, never needs charging, and its 24 dB (SNR) handles snoring, traffic and noisy neighbors for the vast majority of buyers. The 100-night trial from Loop makes it nearly risk-free. If that blocking ever feels insufficient, the Loop Dream ($49.95, 27 dB SNR) is the natural step up before jumping to electronics.
Buy the Soundcore Sleep A20 only if you want what it uniquely offers: falling asleep to rain sounds or podcasts, sleep-tracking data, or a gentle alarm that won't disturb your partner. It's the best powered sleep earbud for side sleepers we've seen — but buy it at the frequent ~$100 sale price, not the $149.99 list. And pair it with the rest of the sleep environment: our smart sleep mask guide covers the darkness half of that equation.

- Materials
- We read the fabric, fill and build details, and note anything the brand doesn’t make clear — including tip sizing ranges and whether parts are washable and replaceable.
- Sleep trials
- We check how long you can try the product at home and whether the trial has conditions. Loop's 100-night trial on the Quiet 2 is among the best in the category.
- Warranty
- We compare warranty length and what it actually covers, in plain language.
- Return policy
- We look at how returns work, who pays for shipping, and how refunds are handled.
Frequently asked questions
Which is better for side sleepers: the Soundcore Sleep A20 or Loop Quiet 2?
Both are designed for side sleepers, but the Loop Quiet 2 has the edge for pure comfort — it sits flush in the ear with no battery bulk to press against the pillow. The Soundcore Sleep A20's low-profile 3.2g buds are also comfortable for most side sleepers, though a minority report feeling them when rolling over. If side-sleeping comfort is your only criterion, the cheaper passive option wins.
Do the Soundcore Sleep A20 have active noise cancellation?
No. The Sleep A20 deliberately skip ANC — there are no microphones at all. Instead they use passive noise isolation from double-flange silicone tips (Soundcore cites up to 30 dB of high-frequency reduction) combined with masking audio like white noise or rain played through the app. This avoids the pressure feeling some people get from ANC during deep sleep.
How long do the Soundcore Sleep A20 last on a charge?
Up to 14 hours in sleep mode on a single charge — more than a full night — and up to 80 hours total with the USB-C charging case. In Bluetooth mode (streaming music or podcasts from your phone), that drops to about 10 hours per charge. For nightly use, you'll recharge the case roughly once every two to three weeks.
Can I still hear my alarm with Loop Quiet 2 earplugs in?
In most cases, yes. The Loop Quiet 2 reduce noise by up to 24 dB (SNR), which muffles snoring, traffic and street noise but doesn't block everything — most users report still hearing a phone alarm across the room. If you sleep through alarms easily, consider the Soundcore Sleep A20 instead: its gentle built-in alarm wakes only you.
How much do the Soundcore Sleep A20 and Loop Quiet 2 cost?
The Soundcore Sleep A20 launched at $149.99 and is frequently discounted to around $100 or less in 2026. The Loop Quiet 2 cost $24.95 from Loop directly — about one-sixth the A20's launch price. Prices checked October 2026.
Key takeaways
- For most side sleepers, the Loop Quiet 2 ($24.95) is the better buy — flush comfort, 24 dB (SNR) of quiet, no charging, 100-night trial.
- The Soundcore Sleep A20 ($149.99, often ~$100 on sale) earns its price only if you want masking audio, sleep tracking, or the silent personal alarm.
- Neither product has active noise cancellation — and that's deliberate. The A20 masks with audio; the Loop simply turns the volume down.
- If you need maximum hush without electronics, the Loop Dream ($49.95, 27 dB SNR) is the step up from the Quiet 2.
