“The Calm aren’t as completely different as they wished to be, however they’re nonetheless strong headphones.”

Welcoming design

Good battery life

Clear, palatable sound

Impactful lively noise cancellation

Inconsistent contact controls

Particular options do not stand out

Know has hit the wearable sound scene with an uncommon focus: These aren’t simply headphones for music, the corporate will let you know, however are supposed to be instruments for data above all else, with options and a design made for the long-term listening that accommodates podcasts and audiobooks.

It’s a daring technique to face out amongst a gaggle of high quality headphones, and it solely pays off if Know can again up its claims with a top quality pair of cans. With its $250 Calm active-noise canceling headphones available (ear?), we’re going to reply this query: Are these new headphones are price it?

Out of the field

Whenever you open as many product packages as I do frequently, it tends to get moderately monotonous. With headphones, there’s going to be a carrying case or pouch, a charging cable, perhaps a three.5mm auxiliary cable, and positively an extreme quantity of studying supplies. In case you’ve seen one, you’ve seen all of them.

Or so I believed.

It’s a refreshing sight to come across packaging just like the one the Know Calm headphones are available. Sure, all these normal equipment are included, however they’re tucked into the field with a way of creativity that I haven’t seen all that usually with headphone firms. Plus, for no matter purpose, Know consists of each a notepad and an artwork piece within the combine, making it nearly nearer to a goodie bag than a set of working instruments. I’m not saying each firm ought to comply with this out-of-the-box packaging fashion, however I’m saying that it piqued my curiosity earlier than I even powered on my pair of Calm cans.

Once I did energy them on, a really informal, non-robotic female voice let me know that the headphones had robotically entered pairing mode. After discovering and connecting them to my telephone, the identical nonchalant voice instructed me that my machine had been paired in the identical tone that a baker would use to inform my order of donuts was prepared on a quiet morning downtown. In different phrases, it’s the calming presence you’ll count on from a pair of headphones with that namesake.

The Know Calm are like most different headphones I’ve tried, in that they’ve Bluetooth 5 know-how built-in, which at this level means I count on them to be freed from pairing points and stuffed with vary. Each rang true but once more, with the Calm surviving the enterprise into my yard and again with out dropping out.


I don’t usually discuss in regards to the carrying case first, however I’m going to make an exception right here. The case for the Calm extra carefully resembles a comforter for a luxurious mattress than it does a protecting shell for headphones, and I imply that in a great way. The case is delicate but sturdy, with an exterior pocket that I might assume would simply home any cables it’s possible you’ll have to convey with you. With a buckle on the bottom of the case for securing it to backpacks or baggage as a bonus, this actually appeared like one of many higher delicate carrying instances for headphones I’ve seen thus far.

The Calm can be found in Black, Sage, or Plum Grey. The ear cups and headband are each welcoming and cozy in your head, a lot in order that I used to be in a position to get pleasure from practically a full day of constant listening with out feeling any type of fatigue that much less pleasant headphones would possibly evoke. And, in what I’m discovering to be true Know trend, the within of the left and proper cups learn “Left ear” and “Proper ear,” versus the normal L or R. We’re speaking about small, largely inconsequential particulars right here, but it surely’s one thing that shouldn’t go unnoticed. Each step of the way in which, Know appears to be making a acutely aware effort to set themselves aside. Thus far, it’s working.

I don’t, nonetheless, very similar to the controls of the Know Calm. Outdoors of the facility/pairing button and the noise-canceling button, each of which work as meant, nearly all of the controls for the Calm come through contact controls on the best earcup. To be truthful, among the instructions labored nicely, like swiping ahead and again to alter tracks, and I feel these controls are usable total. Nevertheless it was definitely an annoyance to cope with inconsistent responses to making an attempt to pause a observe or flip down the amount. It may simply be that my fingers simply aren’t well-suited for the Calm’s contact sensors, but it surely was irritating both approach. By comparability, the Razer Opus has buttons for every of those instructions, which was personally a far simpler solution to function than the method of hoping your touches are interpreted accurately.


Know claims as much as 24 hours of playback on a full battery cost, which is respectable sufficient on this worth vary. That’s higher than the Microsoft Floor Headphones 2, that are priced precisely the identical, and on par with the cheaper Razer Opus. There are funds cans just like the JLab Audio Studio ANC which have higher battery life, however you’re dropping lots of different perks alongside the way in which. That mentioned, 24 hours for the Know Calm appears truthful at this worth level.

Staying on the subject of battery life, the Calm may be charged from a Qi-certified wi-fi charging pad. That’s not included, however you possibly can nonetheless use the USB-C charging cable that’s tossed in. Both approach, Know says you will get three hours of playback after 5 minutes on the charger. Once more, that’s higher than the Floor Headphones 2, the identical because the Beats Solo3 Wi-fi, and probably rivals the Sony WH-1000XM4, which provides you 5 hours of playback after 10 minutes of charging.

Know does make up for the irritating management drawback partially by together with compatibility with Siri for Apple customers and Google Assistant for Android followers. I can merely say “Hey, Google,” and enact any of the instructions I might need had minor bother with through the use of the Calm’s contact controls. I nonetheless suppose the contact controls must be refined to be as straightforward as attainable to make use of, however being able to make my good assistant do my bidding bridges the hole nicely sufficient for now.

The Calm additionally come outfitted with a sensor that may auto pause and play while you take them off and put them again on. I caught them resuming playback whereas they had been nonetheless round my neck a few instances, however for probably the most half, this was a helpful inclusion to those headphones that labored nicely.

Audio high quality

Know has an intriguing know-how it calls “Mindshine know-how.” Mainly, this characteristic processes audio to try to imitate how your ears naturally course of sound. In keeping with Know, as an alternative of your ears having to adapt to a simultaneous wave sample, the sound bounces round your head to create the impact of listening to it in the identical approach you would possibly hear one thing from an exterior supply.

It’s not straightforward for me to decipher how a lot weight this know-how holds when evaluating the sound high quality of the Calm to comparable headphones. With some choices, it appears extra tangible, and with others, it’s laborious to differentiate. The reality of the matter is, it would not likely matter: no matter how a lot that tech would possibly or won’t play into the sound high quality of the Calm, these headphones sound actually good.

I might put these headphones side-by-side with comparatively priced alternate options just like the Razer Opus when it comes to how they sound. The Calm are remarkably clear and supply an ideal sense of stereo separation when enjoying songs like The Doobie Brothers’ Take heed to the Music. In fact, a part of Know’s pitch is that the Calm are headphones designed for extra than simply music listening. As an avid podcast listener, I can attest to the truth that they do sound wonderful for listening to the spoken phrase. Particularly in a time when podcast interviews are being performed over Zoom calls and degrading audio high quality, I used to be in a position to hearken to my weekly dose of Conan O’Brien Wants a Pal and Crime Junkies with extremely clear sound.

The Calm are remarkably clear and supply an ideal sense of stereo separation.

I don’t suppose the Calm are the funds various to the Sony WH-1000XM4 relating to sound, although it’s understandably powerful for many headphones at this worth level to try to compete with that juggernaut and given they’re less expensive, they in all probability shouldn’t. That mentioned, I do suppose the Calm supply strong audio high quality for what they price, and I don’t suppose anybody will likely be disenchanted about how these headphones sound.

Energetic noise cancellation

Along with its Mindshine Know-how, Know has one other piece of know-how that I hadn’t beforehand heard of. It’s referred to as Hush Energetic Noise Cancellation, which Know says is the primary ANC tech to “deal with noise within the mid-high frequency vary, in addition to the low-frequency vary that legacy ANC headphones deal with.”

Nick Woodard/Digital Traits

I can’t touch upon this being the primary know-how to place each ends of the frequency vary in its crosshairs, however right here’s what I can say: After testing the Calm in a number of completely different environments, these headphones have above-average, impactful lively noise cancellation. I’m not precisely ready to take a flight through the present local weather of the world, so I didn’t get an opportunity to see how the Calm reacted to aircraft engine drones or different low frequencies, however with socially-distanced walks within the park and down busy roads, these headphones did very nicely when it got here to blocking out neighboring conversations and undesirable site visitors noise.

These headphones did very nicely when it got here to blocking out neighboring conversations and undesirable site visitors noise.

There are three settings obtainable with that lively noise cancellation button – low, excessive, and off. Plus, you possibly can cup your hand over the best earcup to amplify outdoors noises if you wish to rapidly discuss to a passerby, just about precisely the characteristic we see within the Sony XM4s. It’s a barely awkward gesture, but it surely works nicely and rounds out an efficient lively noise canceling ensemble. Less than Sony requirements, to be clear, however today, who’s?

Our take

With its Calm headphones, Know made pointed decisions with a number of particulars and design elements to assist set its cans other than the pack. Functionally, there’s nothing that blows opponents utterly out of the water, so I can’t say they reach that endeavor. However the Calm are strong headphones for the worth, and they need to be handled as such.

Are there higher alternate options?

For strictly music listening, I’d go for the Razer Opus because it’s received comparable options for $50 much less. However should you’re repeatedly listening to extra than simply tunes, I feel I’d choose the readability of the Calm. Or, you can spend an additional $100 and get one of the best headphones obtainable immediately, the Sony WH-1000XM4.

How lengthy will they final?

Know has a one-year restricted guarantee, in addition to a 45-day assure that you just’ll love these headphones or your a refund. The corporate is assured that these headphones will carry out for the foreseeable future, and I don’t see any purpose to doubt them.

Must you purchase them?

Sure. My unboxing of the Know Calm headphones gave me hope that these can be completely different than anything I’ve examined. Although testing dampened the truth of that concept, it nonetheless proved that these headphones have strong options and audio high quality besides. In case you’ve received $250 to spend, you gained’t be sorry by choosing the Calm.
