The Amazon Echo Buds True Wireless 2021 (2nd generation) are the next generation of the Amazon Echo Buds True Wireless 2019 (1st generation). They have a more comfortable fit and a smaller carrying case than their predecessor. They also use Amazon's active noise cancelling (ANC) technology instead of Bose's active noise reduction (ANR) technology. Unfortunately, their noise isolation performance is worse overall, although they're still fairly effective at blocking office-type noise like background conversations. Their case also holds fewer extra charges than the previous generation. The manufacturer says you have to register these headphones in the Amazon Echo app before pairing with a device.

Our Verdict

7.0 Neutral Sound

The Amazon Echo Buds Gen 2 are satisfactory for neutral sound. Out-of-the-box, their mid and treble response is reasonably well-balanced, so instruments and vocals are present and clear. However, their bass range is very underemphasized, so mixes lack a lot of thump, punch, and warmth. They deliver sound consistently, but like most closed-back, in-ear headphones, they have a bad passive soundstage. Fortunately, you can customize their sound with a graphic EQ in the companion app.

Pros
  • Graphic EQ in app.
Cons
  • Bad passive soundstage.
7.4 Commute/Travel

The Amazon Echo Buds Gen 2 are decent for commute and travel. They're lightweight and comfortable and come with a compact hard plastic case that can protect them when you're on the go. Unfortunately, their ANC can't completely block out the sound of rumbling bus and plane engines. Their continuous battery life of just under five hours isn't the best either, but the case holds a couple of extra charges, so you can top up the battery during long flights.

Pros
  • Case holds two extra charges.
  • Well-built and comfortable.
Cons
  • Somewhat short continuous battery life.
  • ANC struggles with noises like bus and plane engines.
8.3 Sports/Fitness

The Amazon Echo Buds Gen 2 are great for sports and fitness. They come with several differently-sized silicone tips and stability fins, and once you achieve a good fit, they'll be comfortable and stable enough to stay in place during workouts. They're very breathable and compact, like most in-ear headphones. They also have an IPX4 rating for water resistance, although we don't test for it currently. However, their controls are just okay. The touch-sensitive surfaces are easy to activate accidentally, and by default, they don't include volume control.

Pros
  • IPX4 rating for water resistance.
  • Well-built and comfortable.
Cons
  • Mediocre controls.
7.1 Office

The Amazon Echo Buds Gen 2 are decent for office use. They're quite comfortable and do a decent job isolating you from office-type noise like background conversations. Their continuous battery life of just under five hours isn't long enough to last through a typical 9-5 workday, but they come with a case that holds two extra charges. You can also use one earbud while the other one charges. Unfortunately, they don't support multi-device pairing, so they aren't ideal if you switch between your phone and your computer at work.

Pros
  • Good mic recording quality.
  • Well-built and comfortable.
Cons
  • Somewhat short continuous battery life.
  • Mediocre controls.
5.7 Wireless Gaming

The Amazon Echo Buds Gen 2 are Bluetooth-only headphones, so they aren't compatible with PlayStation or Xbox consoles. They work with Bluetooth-enabled PCs, but their latency is too high to be suitable for gaming.

5.6 Wired Gaming

The Amazon Echo Buds Gen 2 are Bluetooth-only headphones that can't be used wired.

6.8 Phone Calls

The Amazon Echo Buds Gen 2 are okay for phone calls. Their mic has a good recording quality, so your voice sounds clear over the phone. However, it doesn't have a very good noise handling performance, so whoever you're talking to might not hear you if you're calling from a noisy place like a subway station. The headphones don't do a great job of isolating you from background noise like rumbling bus and plane engines either, so you may have issues hearing a phone call if you call from a loud place.

Pros
  • Good mic recording quality.
  • Well-built and comfortable.
Cons
  • Mediocre controls.
  • ANC struggles with noises like bus and plane engines.
  • 7.0 Neutral Sound
  • 7.4 Commute/Travel

Differences Between Sizes And Variants

The Amazon Echo Buds 2nd Gen are the next generation of the Amazon Echo Buds True Wireless 2019 (1st generation). They come in two different colors: 'Black' and 'Glacier White'. You can see the label for the unit we tested here; we tested them in 'Black' but expect the other color variant to perform similarly. They come with either a wired or a wireless charging case. We tested the wired charging case. The wireless case has a similar design, but we haven't tested it and don't know if it performs differently.

If you come across another variant or your headphones are different, please let us know in the discussions below, and we'll update our review.

Compared To Other Headphones

The Amazon Echo Buds 2nd Gen are the next generation of the Amazon Echo Buds True Wireless 2019 (1st generation). Unlike the original Echo Buds, which used Bose's active noise reduction (ANR) system, these headphones use Amazon's own ANC technology. Unfortunately, it doesn't offer a huge improvement over their passive noise isolation performance, and overall, they don't block out as much noise as the previous generation or other truly wireless earbuds with ANC like the EarFun Air Pro True Wireless or the Apple AirPods Pro Truly Wireless. Their default sound profile also lacks a lot of bass, but you can customize it with a graphic EQ in the companion app.

If you're looking for other options, check out our recommendations for the best wireless Bluetooth headphones, the best earbuds and in-ears, and the best Bluetooth earbuds.

Amazon Echo Buds True Wireless 2019 (1st generation)

The Amazon Echo Buds True Wireless 2019 (1st generation) and the Amazon Echo Buds True Wireless 2021 (2nd generation) have different strengths, so you may prefer either, depending on your needs. The first generation Echo Buds have a significantly better noise isolation performance. Their case also holds roughly five extra charges, while the Gen 2's case only holds two. On the other hand, the Gen 2's case is more compact and charges with a USB-C connection instead of micro-USB. The earbuds are also smaller and more comfortable. The Gen 2's integrated mic has a much better recording quality as well.

Amazon Echo Buds True Wireless 2023 (3rd generation)

Amazon Echo Buds True Wireless 2021 (2nd generation) are better than the Amazon Echo Buds True Wireless 2023 (3rd generation) for most uses. The 2021 buds block out more noise and have a better mic performance. Their fit is more stable, which is nice for workouts. You might prefer the 2023 if you don't like a deep in-ear fit or want earbuds that let you hear your surroundings. The 2023 version also offers low latency with iOS and Android devices, which helps avoid audio lag while watching videos.

Samsung Galaxy Buds Pro Truly Wireless

The Samsung Galaxy Buds Pro Truly Wireless are better for most purposes than the Amazon Echo Buds True Wireless 2021 (2nd generation). The Samsung have a much more neutral default sound profile, which some listeners may prefer, and their ANC feature does a much better job of blocking out bass-range noises like bus and plane engines. Their case is also more compact and feels sturdier. On the other hand, the Amazon's integrated mic has a much better recording quality. They also come with stability fins and have a much more stable fit, so they may be better suited for use during workouts.

Apple AirPods Pro Truly Wireless

The Apple AirPods Pro Truly Wireless are better for most purposes than the Amazon Echo Buds True Wireless 2021 (2nd generation). The Apple have a better build quality and a more compact case that holds a greater number of extra charges. They also have a significantly better noise isolation performance. The Amazon are more customizable since they have a graphic EQ in their companion app. Their integrated mic also has a much better recording quality.

Google Pixel Buds 2020 Truly Wireless

The Amazon Echo Buds True Wireless 2021 (2nd generation) are better for most purposes than the Google Pixel Buds 2020 Truly Wireless. The Amazon have an ANC feature and isolate you from much more ambient noise. Their integrated mic has a significantly better recording quality, and you can customize their sound profile with a graphic EQ and presets in the companion app. However, the Google come with a case that holds a greater number of additional charges, and their touch-sensitive controls are easier to use.

Samsung Galaxy Buds+ Truly Wireless

The Samsung Galaxy Buds+ Truly Wireless are better headphones than the Amazon Echo Buds True Wireless 2021 (2nd generation). The Samsung have much longer continuous battery life and a slightly better noise isolation performance, even though they don't have ANC. They also have a more neutral default sound profile, which some listeners may prefer. However, the Amazon work with a companion app with a graphic EQ, so you can customize their sound profile. Their integrated mic also has a significantly better recording quality. 

EarFun Air Pro True Wireless

The EarFun Air Pro True Wireless are better for most purposes than the Amazon Echo Buds True Wireless 2021 (2nd generation). The EarFun have a much better noise isolation performance. Their continuous battery life is longer, and they have a bass-rich default sound profile that some listeners may prefer. The Amazon's sound profile lacks bass out-of-the-box, but you can customize it with a graphic EQ in their companion app. They also come with stability fins, which can help with achieving a more stable fit.

The Amazon Echo Buds 2nd Gen are small, roundish truly wireless earbuds with small silicone tips. They look fairly nondescript and don't protrude much from your ears. They have an all-black, all-matte design without the glossy accents from the previous generation. There's a faint Amazon smile logo on the outside of each earbud, and the headphones come in 'Black' or 'Glacier White'.

The Amazon Echo Buds 2nd Gen are comfortable headphones. They're lightweight and come with tips and stability fins in a few different sizes. The tips are color-coded with a different color for each size, so it's easy to see which is which. The earbuds enter pretty far into your ear canal, which some people may find uncomfortable, but they don't go as deep into your ear as the previous generation Amazon Echo Buds True Wireless 2019 (1st generation).

The Amazon Echo Buds 2nd Gen have mediocre controls. The touch-sensitive surfaces on each earbud are very responsive, which makes registering commands easy. However, it can also be a little inconvenient because you can accidentally activate a command. However, you can turn off the touch controls in the app if you wish.

You can tap either earbud once to play and pause music, tap twice to skip forward a track, and three times to skip backward. By default, pressing and holding either earbud for two seconds cycles between the ANC and 'Pass-through' modes. However, if you want to turn off ANC and 'Pass-through', you need to do it in the app. There are no onboard volume controls by default, but you can remap the press-and-hold command for volume, voice assistant, or Spotify. You hear different beeps for different commands, but there are no spoken audio cues.

Build Quality

The Amazon Echo Buds 2nd Gen are well-built headphones. Like the previous generation, Amazon Echo Buds True Wireless 2019 (1st generation), they're made of dense plastic and feel like they can withstand some accidental drops and bumps without breaking. The silicone tips may be a weak point, though, since they feel like they could rip fairly easily. The lid of the case feels flimsy too. They have an IPX4 rating for water resistance, although we don't currently test for it.

Stability

The Amazon Echo Buds 2nd Gen have great stability. They come with several differently-sized tips and stability fins so you can find the best fit for you. Once you achieve a good fit, they're very stable and will stay in place during workouts, even if you move your head around a lot. They're quite stable without any stability fins as well.

After firmware update 603267242, the Amazon Echo Buds 2nd Gen have a bright sound profile. They lack thump, rumble, and punch, so bass-heavy genres like EDM and hip-hop sound hollow and lacking. That said, vocals and lead instruments are present and clear. Fortunately, you can customize it with a graphic EQ in the companion app. There's also an 'Audio Personalization' feature, which allows you to adjust the headphones' sound based on your hearing capabilities. It generates one EQ, and you can't add more.

The Amazon Echo Buds 2nd Gen have a decent peaks and dips performance. There are a couple of large peaks and dips, which indicates that the headphones struggle to follow their sound profile at particular frequencies. A peak in the low-bass range adds thump and rumble, followed by a dip from the high-bass that makes mixes sound cold and lack body. A peak in the low-mid makes vocals and instruments Peaks in the mid-mid and high-mid can make vocals and lead instruments sound muddy, while the low-treble is a little uneven, so vocals and instruments are harsh or veiled, depending on the frequency band. A peak in the mid-treble also makes sibilants like cymbals piercing.

The Amazon Echo Buds 2nd Gen have excellent imaging.

The Amazon Echo Buds 2nd Gen have a bad passive soundstage, typical of closed-back, in-ear headphones. Because they don't interact with your outer ear, their soundstage is perceived as small, and sound seems to come from inside your head rather than from speakers set in the room around you. Also, because of their closed-back design, the soundstage seems less open and spacious compared to most open-back headphones.

The Amazon Echo Buds 2nd Gen have a mediocre noise isolation performance. Unlike the original Amazon Echo Buds True Wireless 2019 (1st generation), they use Amazon's active noise cancelling (ANC) technology rather than Bose's active noise reduction (ANR) system. Unfortunately, they block out much less noise compared to the previous generation.

While the ANC offers an improvement over the passive noise isolation performance when it comes to blocking out bass-range noises like rumbling bus and plane engines, it's still not very good for this purpose. However, whether or not you have ANC turned on, these headphones are decently effective at blocking out sounds like background conversations. They also reduce higher-pitched noises like the hum of an A/C unit.

The manufacturer has reduced the number of additional charges in the case from five to two. On the plus side, they completely recharge in less than an hour, and Amazon advertises that you can get two hours of continuous playback from five minutes of charging, although we haven't tested it. Also, battery performance depends on real-life usage, and your experience may vary.

These headphones also have a standby feature that auto-pauses your audio when you take the earbuds out of your ears, but there's no option to turn it off, which is a bit annoying.

The Amazon Echo Buds 2nd Gen have a good app. It's easy to navigate and has quite a few functions. There's a graphic EQ, an 'Audio Personalization' feature that adjusts the headphones' sound to your hearing capabilities, and a battery indicator for the earbuds and case. You can toggle sidetone on and off, which allows you to hear your voice during calls. You can also choose between ANC and 'Pass-through' mode, which allows you to hear your surroundings while listening to audio. You can also choose to disable both modes. Like the previous generation, the app has a fit tip test to help you pick the best silicone tip size. Unfortunately, Amazon says you need to register your earbuds in the Alexa app before they can be paired with a device, which may be inconvenient for some.

Note: There are some reports from users who say they hear a hissing sound when using pass-through mode. Amazon recommends turning down the pass-through volume in the app or switching it off completely if you experience buzzing or feedback noise.
