Many headphones have an isolating design that physically muffles ambient noise, often referred to as “passive noise-canceling.” Active noise-canceling models go further. These battery-powered headphones use tiny microphones to monitor the frequencies of outside noise, then produce those same frequencies out of phase in an effort to cancel them. Some work with noise reduction turned off, so you can still use them if the batteries die, while others work only with noise cancellation on.
These are typically lighter than over-ear models, and they press on the ears instead of the sides of your head. Some users find them to be more comfortable than over-ear models and less likely to make their ears hot during long listening sessions. On-ear headphones, like over-the-ear, also come in open-back and closed-back varieties, but regardless, they often let in more outside sound because they typically don’t form as tight of a seal with the ear. Some can fold for storage and come with carrying pouches.
Earbud-style headphones range from the disposable models you get on a plane to the ones that are included with your smartphone to high-performance buds that offer sonics rivaling full-size models. Their tiny earpieces rest on the outer ear or need to be inserted into the ear canal, and some models, particularly sport buds, include wings or fins for a more tailored, secure fit.
The mic quality was quite good when we took phone calls in a quiet room, and it worked well for video chats. Beats has programmed in a sensor that dims the mics when you are not speaking to help reduce external noise, though outside they can still pick up noises around you when you are speaking. There is only very mild latency, so you won’t notice a massive delay between sound and video on your phone, laptop, or tablet.
Audio-Technica has announced two new sets of true wireless earbuds: the Audio-Technica ATH-CK3TW and the Audio-Technica ATH-CKS5TW. The CK3TW offers six hours of battery life per charge, with an additional 24 hours of juice in the case, and is expected to be priced at $100. The CKS5TW promises 15 hours of battery life per full charge, with an additional 30 hours in the charging case, and features aptX, SBC, and AAC compatibility; that pair costs $170.

The necessary solution that (nearly) all of these designs share in common is a charging case. Each case protects the earpieces when not in use, and charges them simultaneously. Most of the cases carry two extra full charges, so you can recharge your earphones on the go. It's not unlikely that this weak aspect of the true wireless realm will improve to the point that it will no longer be an issue.
JBL’s Under Armour True Wireless Flash, a workout pair, is lightweight, and the wings keep the earbuds stable in your ears. The metal case is heavy and likely won’t fit in your pocket during a high-impact workout without banging around painfully. The “bionic hearing” (ambient awareness) mode is great for chats between sets but causes the music volume to dip so much that you can’t leave it on all the time for outdoor-running awareness. This pair also lacks volume control.

The lighter-inspired metal charge case of the Klipsch T5 is snazzy but heavy in a pocket. We found that the T5 sounded quite good, but the Klipsch signature oblong tips didn’t hold the earbuds securely enough in our panelists’ ears: After we yawned or spoke, the T5 earbuds started to slide out of our ears, and Brent (who has large ear canals) couldn’t get a seal at all.

Our testers loved that these earbuds were both stylish and comfortable. According to one reviewer, “They fit perfectly. I can barely feel them, which is really good for long-term use.” Unfortunately, this pair may not be the perfect pick for your workout needs, with one of our testers noting that he heard some static when he moved around too much. Stick to the streets and the office and these earbuds should work well for you.
There’s no shortage of options in the realm of true wireless earbuds. Bose was one of the earliest participants in this growing category, and though superior products have since hit shelves, the Bose SoundSport Free are still worth a nod. You’re not getting QuietComfort II levels of audio fidelity here, but the SoundSport Free feature the warm bass response that the brand has become known for. They’re also big, but a positive byproduct of their size is that there’s more surface area to show off the four cool styles you can buy them in, including Blue, Black, Bright Orange, and Ultraviolet.
At first glance, the Elite 75t, which was originally supposed to cost $200 but now sells for $180 (£170 and AU$299), seems more like an evolutionary upgrade from the highly rated Elite 65t. But the updates turn out to be a little more substantial than I first thought. The Elite 75t's smaller size (the buds and case are 20% smaller than the Elite 65t's), its boosted battery life and USB-C charging are significant upgrades. And then there are the smaller changes, like the new charging case design with magnets inside it that make it easier to open and close and to keep the buds inside. While the Elite 75t isn't quite as comfortable to wear as the AirPods Pro and doesn't have active noise canceling, it does sound better, with clearer overall sound and better bass definition, so long as you get a tight seal.

These come in two types. The “closed back” models have sealed ear cups, which keep in more sound and muffle ambient noise. But they might also block out some things you want to hear, such as a doorbell or a ringing phone. “Open back” headphones have openings in the ear cups, which are intended to give the audio a clearer, more natural feel. They’ll let in more external sound, but noise can bleed out as well—perhaps enough to disturb someone nearby.

These headphones hush ambient noise by creating anti-noise that obviates the noise at your ear. They don't eliminate the outside world, but the better models significantly reduce the whoosh of airplanes' air-conditioning systems. Noise-canceling headphones come in all forms, from full-size to earbuds. Since you no longer have to crank up the volume to overcome background noise, this type of headphone lets you listen at lower levels, which leads to reduced ear fatigue. You'll also hear more low-level detail in your music.
Beats includes four sizes of silicone ear tips, so most people will be able to get a good seal. However, the tip material is rather thin, so it tends to crinkle in the ear canal when you first put in the earbuds or adjust them. These also aren’t the most isolating of the earbuds we’ve tested, so you should keep an eye on the volume level when commuting by train; you may also want to select another pair of headphones for in-flight use, such as the 1More Dual Driver BT ANC In-Ear Headphones.
This is the spec that tells you the range of sound that the product is capable of producing measured in Hertz (Hz). If you look on the box of any audio product this number is usually around 20Hz – 20,000Hz, with the first number representing the lowest frequency and the second representing the highest. This number varies depending on the product, but for reference, humans can only hear between 20Hz – 20,000Hz which is why that’s the range most products aim for.
Master & Dynamic MW07 Go: This pair offers a lot of positives. The earbuds are very comfortable and stable in the ears, and we like the separate volume and track controls, although the volume buttons are a tad small for those with larger fingers. The 10-hour battery life and 30-meter Bluetooth range are impressive for this category. The small fabric-wrapped case and the earbuds themselves feel well made. However, although the sound was rather good in our tests, the bass was boosted in a way that could veil male vocals on bass-heavy songs. And we wished the Go had a transparency mode so we didn’t need to take these earbuds out to have a conversation. But if those aren’t dealbreakers for you and you aren’t turned off by the $200 price, they’re solid earbuds.
Sealed models are ideal for private listening, where you don't want the sound to be heard by other people. Open headphones -- such as foam earpad models and many sports designs -- are acoustically transparent and allow outside sound to be heard by the headphone wearer, and a good deal of the headphones' sound will be audible to anyone near the listener.
If you can't afford the AirPods Pro, the Anker Soundcore Liberty Air 2 is a good alternative and are a top model for making calls. Like the AirPods Pro, they do a remarkably good job of muffling ambient noise (callers said they could hear me fine even with a lot of street noise around me). While they don't have active noise canceling, they sound nearly as good, fit comfortably and their noise-isolating design passively seals out a lot of ambient noise. They only cost $100. 

This best in-ear headphones guide covers both traditional Bluetooth earbuds, in which the two earbuds are connected via a cable (usually referred to as a collar or a neckband), and what we call “true wireless” Bluetooth earbuds, which look a little like hearing aids and don’t have a cord connecting them either to your music device or to each other. The microphones are built into the earbuds themselves, as are any track and volume controls, since no cable is available to support a traditional in-line remote. Because these earbuds are small, many don’t have more than a five-hour battery life, although the new Bluetooth chipsets being used in 2019 models allow for longer battery life. Most recharge in their carrying case.

If you're a music lover, chances are you're not happy with your phone or media player's bundled earphones. Most of the time, they sound pretty dismal. Some devices don't come with any earphones at all, but even the models that do include them tend not to offer a high-quality listening experience. Your music and video can definitely benefit from an upgrade.
