The Bose QuietComfort 20 acoustic noise cancelling headphones are in-ear models built for people who want active noise reduction without a battery to charge. They suit commuters, frequent flyers and anyone who uses an iPhone, iPad or Mac and wants a compact pair that works on a wired connection. They are a poor fit for people who need wireless freedom, all-day battery life for calls, or a fit that stays secure during intense workouts. Shoppers who want Bluetooth should look elsewhere, and those who prefer a traditional over-ear design may find the in-ear style less comfortable for long sessions.
Bose QuietComfort 20 Acoustic Noise Cancelling Headphones, Apple Devices (Black)
Product Overview
The QuietComfort 20 is Bose’s wired, in-ear headphone with active noise cancellation built into the cable-mounted control unit. The model name indicates it is designed for Apple devices, with an inline microphone and remote that works with iOS. Unlike wireless noise cancelling earbuds, the QuietComfort 20 draws its power from the connected device through the 3.5 mm plug, so there is no internal battery to recharge or replace. That design choice shapes nearly everything about how the headphones behave, from their weight to their long-term running costs.
Bose positions the QuietComfort 20 as a travel and commuting product. Its target use is blocking steady background sound such as airplane engines, subway rumble, air conditioning and office hum. The noise reduction is generated by a small electronic circuit inside the control unit, which listens to ambient sound and sends an opposing signal to the ear. This works best on low-frequency, continuous noise and does less against sharp, sudden sounds like voices or door slams.
The headphones use silicone or foam-style eartips in multiple sizes, which seal the ear canal. A good seal is essential, because passive isolation and active cancellation both depend on how well the tip fits. Many owners report that the difference between a poor fit and a good one is more noticeable than any difference between two competing models.

Because the QuietComfort 20 is wired and battery-free, its key specifications focus on connection type and compatibility rather than battery hours or driver size. Buyers who need exact driver diameter, frequency response or impedance should check the current manufacturer documentation, since those values are not something this review can confirm with certainty.
Pros & Cons
Pros
- No battery to charge, so the headphones work whenever the source device works.
- Lightweight in-ear design that many owners find comfortable for travel-length wear.
- Active noise cancellation reduces steady background sound such as engine noise.
- Inline controls and microphone are built for Apple device workflows.
- Multiple eartip sizes help achieve a secure seal.
- Compact enough to carry in a pocket or small bag.
Cons
- Wired design limits movement and means a cable can snag on clothing or bags.
- Not Bluetooth, so it does not pair wirelessly with laptops or Android phones without an adapter.
- The cancellation works best on low-frequency sound and is less effective on voices and sudden noises.
- In-ear fit may not suit every ear shape, and a poor seal reduces both isolation and cancellation.
- Some owners find the cable microphone and controls less refined than newer wireless designs.
Performance Analysis
Performance for a headphone like this comes down to three areas: how well it cancels noise, how it sounds with music and calls, and how comfortable it is over time. Because this review is based on manufacturer specifications and patterns in owner feedback rather than personal testing, the analysis below describes what is commonly reported rather than measured results.
Noise cancellation
Active noise cancellation is most effective on consistent, low-pitched sounds. Airplane cabins, train cars and HVAC systems fall into this category, and owners frequently mention a noticeable drop in rumble after switching the cancellation on. Speech, sirens and sudden impacts are harder to suppress, so expect the headphones to reduce these sounds only partially. The result is a quieter environment that still lets you hear your surroundings to a degree, which some people prefer for safety.
Sound quality
Owners generally describe the sound as balanced for everyday listening, with clear mids and a moderate bass presence. Active cancellation can slightly alter the perceived tonal balance, and some listeners find bass sounds a bit thinner when the feature is on. Playing music at a moderate volume tends to work better than cranking the level to overcome background noise, since high volume increases listening fatigue and can mask fine detail.
Comfort and fit
Fit is the factor most often linked to satisfaction. Because the tips must seal the canal, owners with smaller or irregularly shaped ears sometimes need to try several sizes before finding a comfortable match. A secure seal improves both isolation and bass response, so it is worth taking time over. Long wear is generally reported as comfortable for most users, though the cable can pull on the ear if it is not routed over the top of the ear or secured with a clip.
Calls and controls
The inline microphone is intended for phone calls and voice assistants on Apple devices. Owners typically report that voices come through clearly in quiet settings but can be less clear in windy or loud environments, a common limitation of inline microphones. The control button handles play, pause, track skipping and call answering, which many users find convenient for quick adjustments.
Who Should Buy This Product?
The QuietComfort 20 is a practical match for several types of buyers. Frequent flyers who want noise reduction on long flights without managing a battery are a strong fit, as are commuters who ride trains or buses and want a lightweight pair that works without charging. iPhone and iPad owners who already keep a 3.5 mm adapter or Lightning/USB-C dongle in their bag may also appreciate the simple setup.
Shoppers who should skip this model include anyone who needs Bluetooth, such as people who use a laptop or Android phone daily and dislike cables. Those who spend long hours on video calls in noisy spaces may find the inline microphone less reliable than a boom-mic headset. People who want the deepest possible isolation or who prefer over-ear comfort for sessions lasting several hours should consider a different style entirely.
Buying Guide
Before buying any noise cancelling headphone, decide on three things: connection type, form factor and the environments you plan to use them in. A wired in-ear model like the QuietComfort 20 is ideal when simplicity and zero charging matter most. A wireless option gives more freedom but adds a battery that eventually wears down. Over-ear designs usually offer larger drivers and more comfort for long sessions but take up more space in a bag.
Check the connector before purchase. The QuietComfort 20 uses a 3.5 mm plug, so an iPhone without a headphone jack will need a compatible adapter. Confirm the fit by trying different eartip sizes, and do not rely on the box alone. A secure seal is the single biggest factor in how well both passive and active isolation perform.

FAQ
Do the Bose QuietComfort 20 headphones need batteries?
No. The headphones draw power from the device they are plugged into, so there is no internal battery to charge. The noise cancellation circuit runs on that connected power.
Do they work with Android phones?
They use a standard 3.5 mm plug, so they can connect to Android devices with a headphone jack. The inline controls and microphone are designed for Apple devices, so some button functions may not behave the same way on Android.
Are they good for flights?
Many owners use them on flights because the cancellation reduces steady engine noise. Because they are wired and battery-free, they are convenient for long trips where you do not want to manage charging.
How do I get the best noise cancellation from them?
Choose the eartip size that gives a snug seal without discomfort. A good seal improves both passive isolation and the effectiveness of the active circuit. Test the fit in a quiet room before relying on them in noisy environments.
Can I use them for phone calls?
Yes, the inline microphone supports calls on compatible devices. Voice clarity is generally good in quiet settings, but wind and loud surroundings can reduce it.
Are they comfortable for long wear?
Most owners report comfort for typical travel and commuting sessions. Fit varies from person to person, so if pressure or soreness develops, try a different eartip size or reposition the cable.
What is the difference between the QuietComfort 20 and the QuietComfort 20i?
The 20i is a closely related model in the same family. Check current product details and compatibility notes for each version, because control layout and device support can differ between variants.
Final Verdict
The Bose QuietComfort 20 acoustic noise cancelling headphones are a sensible choice for travelers, commuters and Apple device users who want noise reduction without charging a battery. Their wired, in-ear design is simple and dependable, and the active cancellation does a useful job on steady background sound. The trade-offs are real: no Bluetooth, a cable to manage, and a fit that depends heavily on your ear shape. If those trade-offs fit your routine, they are worth considering. If you need wireless freedom or long-session comfort, look at the alternatives above first.
