Amazon Echo Buds 2nd Gen Review: ANC, Battery Life, and Alexa

The Amazon Echo Buds (2nd Gen, model B085M2N586) are wireless earbuds with active noise cancellation built for people already using Alexa. They launched at $119.99, but you can pick them up for $39.99 now. That price drop changes the conversation entirely. For less than $40, you get Bluetooth 5.0, IPX4 water resistance, ANC, and hands-free voice control that ties directly into your smart home. They won't replace a $250 pair of Sony or Bose buds, but they don't need to.

This review covers the 2nd Gen model (B085M2N586). I've used the Echo Buds as my go-to commute earbuds for several weeks. The thing that surprised me most was how well ANC handles low-frequency rumble. On a bus or train, the hum just fades. Office HVAC noise? Gone. They're genuinely usable, not just "has ANC on paper."

How Is the Sound Quality on Echo Buds 2nd Gen?

The Echo Buds lean bass-forward. Podcasts and spoken audio sound full and warm. Music with heavy low-end (hip-hop, electronic, rock) comes across well. Acoustic and classical genres feel a little muddy compared to a more neutral-tuned earbud. The highs are present but not bright. That's a deliberate tuning choice, and for most casual listening it works fine.

ANC on these buds is strongest in mid-range frequencies. Airplane cabin drone, office air conditioning, bus engine noise - all handled well. Higher-pitched sounds, like a conversation across the room, still bleed through. That's normal for earbuds at this price. Passthrough mode (Amazon calls it "Alexa, turn on passthrough" or a simple tap) works cleanly when you need to hear your surroundings without pulling a bud out.

The drivers sound better than you'd expect from a $40 earbud. They won't embarrass themselves next to much pricier options on most genres. For background music and podcast listening, they're more than good enough.

ANC Performance at $39.99

At this price, ANC is rare. Most sub-$50 earbuds skip it entirely. The Echo Buds deliver real noise reduction - not perfect, but functional. In my testing, the ANC cut ambient office noise noticeably on the first toggle. Switching between ANC on and off made an audible difference every time.

How Does Alexa Integration Work on Echo Buds?

This is where the Echo Buds earn their name. Say "Alexa" out loud and your voice assistant wakes up without touching your phone. You can ask Alexa to play music, set a timer, check the weather, control smart home devices, or make calls through your phone's contact list. It works over Bluetooth and passes requests through the Alexa app on iOS or Android.

The hands-free calling feature is useful in practice. When a call comes in, you hear a chime and can answer by saying "Alexa, answer" or by double-tapping. Call quality is acceptable for short conversations - the microphones handle a quiet indoor environment well. Background noise outside can muddy pickup, but it's not unusual for earbuds at this price.

Smart home control through the Echo Buds is genuinely practical. I found myself turning off lights and adjusting my thermostat while doing dishes without reaching for my phone or a smart speaker. If you already have Alexa devices at home, this extends that ecosystem into your ears.

The Alexa app is required for setup and some features. Setup takes about five minutes on both iOS and Android. Firmware updates push automatically through the app, which is a small but welcome detail. The buds also support multipoint connection - they can stay paired to two devices simultaneously, so switching between your phone and laptop doesn't require manual re-pairing.

What Is the Battery Life and How Comfortable Are the Echo Buds?

Battery life breaks down like this: five hours per charge in the earbuds themselves, with three full recharges available in the case. Total is 20 hours of listening before the case itself needs charging. With ANC on, expect closer to four hours per charge in the buds. That's a realistic number for a full workday if you charge the case overnight.

The case is compact and charges over USB-C. There's no wireless (Qi) charging on the 2nd Gen - that feature came with the 3rd Gen. If wireless charging matters to you, that's worth knowing before you buy.

Fit uses silicone ear tips in four sizes (XS, S, M, L) with a wing-tip design that locks the earbud against the outer ear. The wing tips aren't removable on their own - the whole earbud has a contoured shape. In my experience, the medium tips fit securely through an hour-long walk without adjustment. People with smaller ear canals may want to test the XS tips first.

IPX4 water resistance means sweat and light rain are fine. You won't want to swim with them or rinse them under a tap, but normal workout use is within spec.

Echo Buds Battery Specs at a Glance

• Earbuds: 5 hours (ANC off) / ~4 hours (ANC on)
• Total with case: 20 hours (ANC off) / ~15 hours (ANC on)
• Charging: USB-C, no wireless charging
• Case weight: 61 grams total

Who Should Buy Amazon Echo Buds 2nd Gen?

The honest answer is: Alexa users who want earbuds under $50. If you have an Echo device at home, a Fire TV, or a Ring doorbell, the Echo Buds slot into that ecosystem without friction. The hands-free Alexa access feels natural if you're already talking to Alexa at home.

They're also a strong pick for commuters. ANC on a bus or train genuinely reduces fatigue over a long ride. Five hours per charge covers most commutes, and the case gives you backup power during the day.

Who shouldn't buy them? Anyone looking for audiophile-grade sound, wireless charging, or premium build materials should look elsewhere. The plastic case feels functional rather than premium. And if you're deep in the Google or Apple ecosystem, the Alexa dependency becomes a friction point - the buds work with iOS and Android, but features like Siri or Google Assistant aren't available hands-free.

At $39.99, the Echo Buds represent more value than most earbuds in the category. It's rare to get real ANC, 20-hour total battery, Bluetooth 5.0, and voice assistant integration below $50. That's not marketing - that's just the math at the current price.

Frequently Asked Questions

Do Echo Buds 2nd Gen work with iPhones?

Yes. Echo Buds pair with any Bluetooth device, including iPhones. You'll need the Alexa app (free on iOS) for full setup and features. Hands-free Alexa works the same on iOS as Android. Siri is not accessible hands-free through the buds.

Do Echo Buds 2nd Gen have wireless charging?

No. The 2nd Gen case charges via USB-C only. Wireless Qi charging was added in the 3rd Gen model. If you want wireless charging, you'll need to step up to the newer version or a different brand.

How does ANC on Echo Buds compare to Sony and Bose?

Echo Buds ANC reduces mid-range frequencies effectively - engine noise, HVAC hum, and office background sound. Sony WF-1000XM5 and Bose QuietComfort Earbuds II offer stronger, more adaptive ANC across a wider frequency range. At $39.99 vs. $200-$280, the Echo Buds are not in the same class, but the ANC is real and useful for everyday commutes.
