Enjoy the subtle details of your music, without the ear fatigue.

Meet the most comfortable over ear headphones.


If you’ve ever experienced ear fatigue from headphones the way I do, it really prevents you from fully appreciating the sound coming out of them. The sound quality, the depth of audio, none of it matters if your ears are hurting from too much pressure.


Introducing the Calm Bluetooth ANC Headphones from Know


Yes, they sound realistically orchestral, full and rich, but we’ll talk about that later. It’s because they’re so comfortable to wear that you can actually take the time to decide for yourself how good your music sounds.


Wear them for hours on end. No listening fatigue.
Oh, and you finally have a battery that will outlast your longest listening sessions. The Calm Bluetooth ANC Headphones will last 24 hours on a single charge.


(And if you’re in a rush, charge them up for 5 minutes and they’ll last up to 3 hours!)


MindShine Technology mimics your natural hearing patterns
There’s more to reduced listening fatigue than physical pressure alone. With other headphones, your ears are forced to to adapt to a forced simultaneous wave pattern. It’s a big strain on your ears, so even though you may not notice it at first, eventually you’ll feel like you need a break from listening.


Stronger Active Noise Canceling Technology


The Calm Bluetooth ANC Headphones implement what’s called MindShine Technology. They mimic the way you naturally process sound, which takes away the strain your ears normally experience with other headphones.


The same goes for its built in Active Noise Cancellation. It’s powerful. And it’s cutting edge in that it eliminates a wider range of frequencies than most other average ANC implementations. The others target low range frequencies from 200-500hz. The Calm Bluetooth ANC Headphones target frequencies up to 1,500hz.


Well, there’s also a ‘Low’ setting if you’re not in a loud environment that needs the full on cancellation.


Sound Quality is still the star of the show


I know. The hallmark of quality headphones is accurate, high quality audio reproduction. All that comfortable wearing stuff is what gave me a chance to finally assess if my over ear headphones are any good. And these cans really deliver!


I know a bunch of DAKonians who are still staunchly anti-Bluetooth because it’s lossy and compresses your music. I was in that camp myself until just a few years ago.


But the power of integrated software and codecs have gotten so good, that the enhanced digital sound processing they implemented in the Calm Headphones will have even the last anti-Bluetooth holdouts nodding their heads in approval. Your music is in full display, full detail.


Oh, about details…


Extra Details that Make the Calm Bluetooth ANC Headphones an Instant Home Run


It’s just so thoughtfully designed. Every subtle stitch. It’s the little things like:


When you take off your headphones, you music pauses. Put them back on and they reusme where you left off.


-Wireless Charging Compatible
  Place the left cup on a wireless charging pad (like our OctoGrip Wireless Charging Powerbanks) to recharge without any cables. It includes a Type C charging cable for traditional charging, too.


-High Quality Mic
Use as a headset for phone calls and Zoom video conferences. You’ll be heard loud and clear.
-Ambient Transparency Mode
Need to hear what’s going on around you in the real world? Place your hand over the ear cup for the ambient pass-through mode. You’ll be fully aware of your surroundings.


-Elegant Touch Controls
You’re just an easy swipe or tap away from adjusting the track, play/pause, volume control, answering phone calls, and Siri.

-Well-Designed Carrying Case
Functional and handy. Fits your Calm Bluetooth ANC Headphones and the included accessories. I love how thoughtful this is.


-Bluetooth or Wired, You Choose
Ok, a big concession to the audio ‘purists’. Even if you still won’t try Bluetooth, your Calm Headphones have 3.5mm jack so you can plug in just like the dinosaurs used to do. You even get the cable included.


DAK’s Ironclad Guarantee
I’ve been testing prototypes and samples of over ear headphones for over five years. This is the first one I’ve agreed to share on DAK. So, yes, I’m very confident that you’ll love your pair as much as I do.


If you decide they don’t cut it for you?
That’s fine. Music is personal.

Using the DAK brush along with anti-static cleaning products has created the best sound I've ever heard from my records!

This is a surprise for my wife who has been chirping about no space on her phone and her cloud is full too. DAK to the rescue!

Better features than my Bose. I've had the Know headphones for several weeks. It took me a little bit to get used to the different controls but I'm impressed! The fact that they will pause the app that is playing on my iPhone when I have to slide them off for a second is great! Neither my former Bose over the ear nor Bose Sport headphones could do that. They're comfortable and the sound quality is great!

Great Headphones. These are better than any other brand I have had and I had everything from $500 to $50 and these headphones are everything they claim to be and then some.
