Most people scoff at the thought of spending $200 on headphones. But Shure ups the ante with its premium active noise cancelling (ANC) headphones, the Shure AONIC 50, which costs $299 USD. But don’t let the price talk you out of considering this headset, because it is worth the money. This is one of the most comfortable headsets around, making it a commuter’s best friend.

Editor’s note: this Shure AONIC 50 review was updated on October 12, 2021, to include new information about the ShurePlus PLAY app and to make note of the Bose QuietComfort 45 as an alternative.

Who should get the Shure AONIC 50?

The Shure AONIC 50 is available in black and brown.

  • Remote workers should get these noise cancelling headphones. Shure’s ANC, while not the best, is objective and keeps me focused throughout the workday.
  • Frequent travelers will appreciate the comfortable fit and the 20-hour battery life.
  • Audiophiles will cling to these headphones as they have a 3.5mm headphone jack for anyone with FLAC libraries, and a slew of high-quality Bluetooth codecs aptX, aptX HD, aptX Low Latency, AAC, LDAC are supported to get optimal wireless audio. Additionally, the charging port is also a data input, so you can listen to your music over a USB-C cable (instantly making this the best USB-C headset on the market).

What is the Shure AONIC 50 like?

The earpads twist off and are easy to wipe clean.

Everything from the packaging, carrying case, and headset just screams quality with the Shure AONIC 50. The plastic housings look great and keep things lightweight, while the stitched leather headband looks sophisticated, yet eye-catching. Leather-wrapped earpads are just as handsome and happen to be removable. This kind of design elongates the life of headphones while also making them easier to clean.

Beauty and grace aside, the AONIC 50 isn’t very portable compared to its main competitor, the Sony WH-1000XM4. Unlike headphones from Sony, Bose, and Audio-Technica, Shure doesn’t include folding hinges. The ear cups rotate flat for storage, but it would be nice to see a more versatile form factor. On the other hand, the structure makes the AONIC 50 more durable and less susceptible to breakage.

The Shure AONIC 50 are my favorite noise cancelling headphones to date.

While this is a large headset, it manages to remain comfortable with glasses. Headphones usually give me pause as a bespectacled listener, but these work incredibly well with my frames. The clamping force is reasonable, and the headband evenly distributes weight, so hot spots shouldn’t present themselves on top of your head.

How do you control playback?

Shure skipped the touch controls, instead opting for onboard tactile buttons.

The right ear cup houses all of the buttons you need to control the headset including a noise cancelling and ambient listening switch, power and Bluetooth pairing button, and volume/playback controls. It is easy to find the raised multifunction button for accessing Google Assistant, which is supremely useful for setting timers while baking.

Take full control with the ShurePlus PLAY app

The ShurePlus PLAY mobile app's custom EQ module open for the Shure AONIC 50.

You can create your own custom EQ with the Shure headphones, or choose from five preset EQ options.

Shure’s mobile app is available on both iOS and Android and app functionality is identical across platforms. If you want to control the noise cancelling intensity and how much environmental noise is let in via ambient aware mode, you have to get the ShurePlus PLAY app. It’s also an easy way to check battery levels, play local music files, and receive firmware updates.

You can also EQ the sound if you’re not a fan of Shure’s default sound signature. According to a Shure representative, it is now a hardware EQ that applies to music played beyond the PLAY app. This means any EQ you create will be applied in apps like Spotify or Apple Music. Of course, you can upload your music to the PLAY app’s library if you’d like, which is great for those with lossless libraries.

On July 14, 2020, the company released firmware version 0.4.9 to improve ambient noise mode, thereby minimizing feedback. It also improved call quality, and vocal accuracy. The headset is now enabled to relay a “connected” message when successfully connecting to specific soundbars, TV sets, and Bluetooth adapters.

Is the Shure AONIC 50 noise cancelling any good?

A chart depicting the Shure AONIC 50 noise cancelling performance (firmware 0.4.9), and low frequencies are heavily attenuated making them four times quieter with ANC enabled than when it's disabled.

The Shure AONIC 50 noise cancelling performance is stellar, particularly when it comes to combating low-frequency sounds. This was measured with firmware 0.4.9.

The noise cancelling is very good, especially when it comes to blocking out low-frequency sounds like A/C units, washing machines, and outside traffic. The Sony WH-1000XM4 more effectively cancels out midrange sounds, but this is still impressive.

Not only is a good pair of ANC headphones a great productivity tool, but it can also protect you from certain types of hearing loss. Since the well-padded headphones are so good at combating external sounds, you’re less likely to increase the volume to dangerous levels. If you spend a lot of time flying or commuting via subway, the Shure AONIC 50 could help preserve your hearing.

ANC headphones are an excellent tool for anyone who works from home.

Passive isolation is also great thanks to the high-density memory foam earpads. This kind of material really lets the noise cancelling technology shine and effectively targets sounds higher than 1kHz, with some attenuation of sounds below 1kHz too.

What Bluetooth codecs does the Shure AONIC 50 support?

On-the-move audiophiles will enjoy these because all of the major Bluetooth codecs are supported: aptX, aptX HD, aptX Low Latency, AAC, LDAC. Whether you’re listening from an iPhone or Android smartphone, you’re bound to experience the best quality audio while moving about. The Bluetooth 5.0 firmware grants a 10-meter wireless range and contributes to the headset’s 20-hour official battery life.

In order to adjust noise cancelling and ambient mode intensity, a user must download the ShurPlus PLAY app.

Bluetooth multipoint is supported by the Shure AONIC 50, so you can connect the headset to two devices at a time. I use this all the time to work from home as a means of keeping one ear on incoming calls and the other on desktop notifications and music.

You can use the provided 2.5-to-3.5mm cable to hardwire the headset from the 2.5mm input on the left headphone. When you listen by wire, you can still use the noise cancelling and passthrough audio functions of the headset. Doing so will still drain the headset’s battery though.

How good is the battery life on the AONIC 50?

Shure claims a 20-hour battery life with noise cancelling turned on. Our battery tests yielded 19 hours, 46 minutes of playtime on a single charge. To recharge the headset to full capacity, connect it to the provided USB-C cable for a few hours. The LED indicator slowly blinks red when battery life is low and remains a solid red when charging.

What does the Shure AONIC 50 sound like?

A chart depicting the Shure AONIC 50 frequency response (firmware 0.4.9); sub-bass and treble notes have been amplified with the first firmware update.

The Shure AONIC 50 amplifies upper-bass notes which helps fundamental vocal frequencies stand out. This was measured with firmware 0.4.9.

As a legacy audio company, Shure knows how to create a pleasing sound signature and keeps the frequency response nice and neutral with these 50mm dynamic drivers. The 70-300Hz bump makes it easier to hear vocals, which is great for powerful, soulful vocals from the likes of Brittany Howard. Oh, and don’t worry about that short dip from 2-4kHz, that’s something we often see from well-informed audio companies—this kind of under-emphasis minimizes the loudness of naturally occurring resonances within the ear canal.

Editor’s note: the firmware version 0.4.9 resolved an issue that whereby high-frequency sound artifacts were problematic when using LDAC at 88.2 or 96kHz. We also measured a more neutral sub-bass response with firmware 0.4.9, compared to 0.4.1.

Lows, mids, and highs

Samm Henshaw’s song Church (feat. EARTHGANG) sounds wonderful through the AONIC 50. The song begins with a choir harmonizing “Ohs” while quick, repeated claps are relayed through both channels. Just 10 seconds into the track, Henshaw raps the first verse as the piano chord pattern Bm-D-E underscores his vocals. Other drivers would struggle to clearly reproduce this coalescing instrumentation, but not the AONIC 50.

The Shure AONIC 50 have excellent sound quality.

Henshaw’s vocals are easy to hear throughout the song, even during the choruses which introduce bassy brass horns that might easily mask his voice through the wrong headset. I love how clearly the tambourine comes through even as the bassline kicks in at 3:05. This instance showcases the audio engineering prowess that went into this headset.

How’s the microphone on the AONIC 50?

Microphone quality is very good if you’re operating on firmware version 0.4.9, rather than 0.4.1. The original microphone quality was good enough to get you through any sort of professional conference call or video chat, but Shure further improved accurate vocal reproduction with its first firmware update.

The Philips Fidelio X2 open-back headphones lean against the Shure AONIC 50 Bluetooth headphones with noise cancelling.

The AONIC 50 microphone is good but can’t compare to an external boom mic.

Now, the high-pass filter is less intense, so fundamental vocal frequencies are relayed accurately; in other words, you won’t sound quite so “hollow.” The de-emphasis from 50-300Hz is less dramatic than during our initial review. As you can hear from the voice demo below, speech intelligibility is a non-issue, despite my voice being low: the fundamental frequency range of my voice ranges from 160-240Hz. In total, the AONIC 50 houses six microphones, two of which are beamforming (right cup only), one per cup for Environment Mode and feed-forward ANC, and two per headphone for feedback ANC.

As we noted in our 2020 scoring audit, most people prefer a response like this in their headphones and headsets because it combats something called the proximity effect. By reducing the sensitivity to lower-frequency sounds, you avoid that “too-close-to-the-mic” overly-bassy sound that some headsets imbue their audio with. Additionally, higher-frequency sounds that are needed for speech intelligibility are also easier to hear. If there’s a microphone company you should trust, it’s definitely the makers of the most iconic vocal mics of all time.

As of March 24, 2021, 1,100 readers rated the above mic sample as somewhere between “okay” and “good.” This is a pretty typical result for an embedded microphone system, and at the upper end of what you should expect to get out of any products of this type.

Should you buy the Shure AONIC 50?

The ear cups don’t rotate up towards the headband.

Yes, the Shure AONIC 50 is worth getting and stands as my favorite pair of noise cancelling headphones. The headset merits its price: sound quality is stellar right out of the gate, while comfort and build quality are great. The Shure AONIC 50 is sure to serve you well for years to come and makes a strong case for viewing expensive headphones as an investment.

Listeners who want to save quite a bit of money for similarly effective noise cancelling should consider the Sennheiser PXC 550-II. This originally retailed for $349, and can now be had for a reasonable price of $199. The PXC 550-II doesn’t have the same premium build quality as the Shure AONIC 50, but it does have a lightweight, travel-friendly design. Yes, the microUSB input is an inconvenience but a small one considering the extremely high value of this Sennheiser headset.

Shure AONIC 50 vs Sony WH-1000XM4

Sony’s latest flagship headset makes the top of our best lists, because the Sony WH-1000XM4 checks all the right boxes: it’s (relatively) affordable, sounds great, has top-notch noise cancelling, and lasts for 20 hours with ANC on. It has yet to be usurped by another set of cans, but the Shure AONIC 50 gives Sony a run for its money.

The addition of Bluetooth multipoint means you can stay connected to two devices at once.

Sony’s headset is made from less premium materials—another reason costs are lower—but the plastic ear cups are touch-sensitive. It’s also a more portable headset. The ear cups can both fold flat and rotate up toward the headband, providing listeners with more options on how to store it. Another difference: Bluetooth codec support. The Sony WH-1000XM4 supports SBC, AAC, and LDAC, while the Shure AONIC 50 supports all of those codecs and aptX, aptX HD, and aptX Low Latency.

Don’t miss: Shure AONIC 50 vs Sony WH-1000XM4

Both headset apps let users dictate ANC and passthrough intensity, EQ the sound, and more. Sony and Shure each know how to make an exceptional headset. Listeners who demand the best when it comes to construction, sound, and noise cancelling need Shure’s headphones. For most consumers, the Sony WH-1000XM4 is more than good enough. For a better deal with nearly the same design, get the Sony WH-1000XM3 instead.

Shure AONIC 50 vs Bose Noise Cancelling Headphones 700

Neither the Shure Aonic 50 nor the Bose Headphones 700 (pictured, black) have folding hinges.

The Bose 700 Headphones use touch controls and have three buttons in total, one of which is for pairing, another is for controlling the level of ANC, and a third which can activate the Google Assistant.

The all-plastic Bose Headphones 700 has a similar architecture to the Shure AONIC 50 as the ear cups only rotate flat and not inward. Just like Sony’s headphones, the Bose Noise Cancelling Headphones 700 have touch-sensitive panels that register gesture controls. Bose’s headset costs nearly the same as Shure’s headset. You’re paying for the company’s respected reputation—update shenanigans aside.

The Bose Headphones 700 lacks high-quality codec support and includes only SBC and AAC. This is perfectly fine for iPhone users, and is compatible with Android—but the problem is that performance can be highly variable on Android devices from phone to phone. This means you may not necessarily get high-quality audio with this expensive headset.

A plot showing the excellent active noise cancelling performance of the Bose Noise cancelling headphones 700.

With the latest firmware, the maximum ANC performance is very good.

Battery life is great; our testing yielded just over 21 hours of listening on a single charge with ANC maxed out. However, noise cancelling leaves a lot to be desired. There’s no debate: the Shure AONIC 50 handily outperforms the Bose 700 here. Sound quality is a bit closer though, as the Bose headphones have a neutral-leaning frequency response until the 1kHz-mark. We see a dip here that functions similarly to Shure’s slight treble dip.

If you’re torn between the Bose Headphones 700 and Shure AONIC 50, get Shure’s headset. Or, settle for slightly worse microphones and build quality and grab the WH-1000XM4 instead.

Listeners who want the comfort of the AONIC 50 with the sleek design of the Bose Noise Cancelling Headphones 700 should check out the Bose QuietComfort 45.

What about the Apple AirPods Max?

The headphones come with its smart case and a charging cable, and nothing else.

The AirPods Max is a completely different beast than the Shure AONIC 50: it relies heavily on advanced software, so much so that each headphone houses Apple’s H1 chip. This processing power is required to perform certain tasks like optimal active noise cancelling, Transparency mode, Spatial Audio, and more. Like the Shure AONIC 50, the AirPods Max features tactile button controls only. It has its quirks; for one, you can’t power the AirPods Max off unless it’s sheathed in its smart case. Apple’s headphones are astronomically priced at $549 USD, so you could practically buy two Shure headsets for the price of one AirPods Max.

If you have an iPhone, the AirPods Max might be worth it because they work seamlessly within the Apple ecosystem. Automatic device switching with the AirPods Max is a breeze, and hands-free Siri access makes it that much easier to execute basic commands. Even still, most of us will be perfectly happy with any alternative headset from Bose, Sony, Sennheiser, or Shure.

Frequently Asked Questions

Can it support listening via 3.5mm jack and Bluetooth calls simultaneously?

If I understand this question correctly, you want to know if you can listen to music over 3.5mm connection, while having a phone call over Bluetooth. No, you'll have to pick one input (3.5mm or Bluetooth). Depending on your device and apps, you can listen to music and be on a phone call at the same time, but it'll have to be using the same connection.

Should I get the Aonic 50 or the Sony WH-1000XM4?

If you want the best active noise cancelling headphones available, you can't beat the Shure AONIC 50. That being said, the Sony WH-1000XM4 is actually more effective at cancelling low and low-mid frequency noises than the AONIC 50. The AONIC 50 support more Bluetooth codecs than the Sony headphones do, but both support Bluetooth multipoint. The AONIC 50 are quite a bit more expensive than the WH-1000XM4, and if you want to save even more money, the Sony WH-1000XM3 are still a great pair of headphones.

Do the headphones slide forward when looking down?

The headphones slide forward a bit when looking down, but the effect is minimal. The headband material creates enough friction that it's unlikely to slide completely forward and down toward the forehead.

Do the Shure headphones put less clamping force on the listener compared to the Bose Noise Cancelling Headphones 700?

Since the Shure Aonic 50 ear cups are more spaced apart than the Bose Noise Cancelling Headphones 700 ear cups, the clamping force should be lessened. What's comfortable for one listener may not be comfortable for another, though, as you could run into other issues with the Shure headset; for instance, Shure's headphones are 80g heavier than Bose's. This could create discomfort for some listeners, even though it didn't for Lily.

Are they suitable for lengthy listening sessions?

Yes! Lily here, and I found the Shure Aonic 50 extremely comfortable during long listening sessions whether I was wearing glasses or contacts. The headband does a great job of evenly distributing weight across the top of the head while the sliding adjustment mechanism is suitable for small and large heads. The memory foam ear cups also do a great job of mitigating any potential pain points.

Are the housings plastic, and what are the earpads made out of?

We reached out to Shure about the Aoinc 50 and the representative shared the following. "The yokes (the parts that attach the earcups to the headband) are aluminum. The earcups are resin (plastic). The earpad cushions are synthetic leather, sometimes called 'protein leather.' It is not an animal product."

Are these better than the Sennheiser Momentum 3.0 ?

The Shure Aonic 50 has significantly better noise cancelling and sound quality compared to the Sennheiser Momentum 3.0, the latter of which boosts bass frequencies to sound twice as loud as mids. This may be preferred if you listen to EDM or hip-hop but won't be pleasant for listeners in search of a platonic sound signature. Battery life is also much better with Shure's headset as it grants approximately seven more hours of playtime on a single charge. There are differences in build quality, though, as the Sennheiser Momentum Wireless 3.0 uses genuine leather for its memory foam earpads while the Shure Aonic 50 uses synthetic material. Plus, Sennheiser's headphones don't fold flat but do collapse towards the headband. The Momentum Wireless 3 is a bit older than Shure's headphones and costs $50 less.

How do these compare to the Master and Dynamic MW65?

The Shure Aonic 50 is a much better pair of noise cancelling headphones than the Master & Dynamic MW65. Low and midrange frequencies are rendered null with the Aonic 50 compared to the MW65. Battery life is about the same with both headsets, but sound quality is more accurate and imaging more engaging with Shure's headphones. Microphone quality is also better with the Shure Aonic 50, but one reason to get the Master & Dynamic MW65 instead: build quality. Shure's headphones use a synthetic leather material, making them vegan, but Master & Dynamic sources premium materials like lambskin leather. That said, the Shure Aonic 50 headphones are more comfortable despite being ~100g heavier.

The sub-bass at 20 Hz is -10dB; how does this sub-bass with the Shure Aonic 50 compared to the Bose Noise Cancelling Headphones 700 and Sony WH-1000XM3?

Extremely low sub-bass frequencies (20Hz) are quieter with the Shure Aonic 50 compared to the Sony WH-1000XM3 and Bose Noise Cancelling Headphones 700. That said, it's unlikely you can perceive a 20Hz frequency among instrumental din as hearing degrades over time. If you want, feel free to test your hearing here: we include a 20Hz audio sample.

Does the heavy weight (335 grams) strain your neck during a prolonged use??

That's a pretty hefty weight, but we didn't really run into issues. Those pads are pretty thick, and the headset distributes weight well.
