Those familiar with our products will know that Nothing Ear is the successor to Ear (2). Maintaining its iconic design, the story of Nothing Ear lies primarily on the *inside.* In this thread, we’ve delved into the internals of Nothing Ear to create a macro teardown photography series, highlighting all the improvements that our teams have made and admiring some of the great engineering within. Many of us here at Nothing are [fans of iFixIt](https://www.ifixit.com/) and their contributors - we were inspired by their great teardown content and guides and decided to have a go ourselves. For our series, we took a fast-tracked route and picked one of each component straight from our production line, saving us some fiddly disassembly. We worked with a [London-based photographer, David Wilman](https://www.davidwilman.com/), to create some compositions of the inner workings in high detail. The process was a lot of fun, so we hope you enjoy the teardown images! ***Let’s Look Inside ‎*** **Inside the Left Ear** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-05-14/1715705346-269943-ig-16-9-2.jpg "banner") **🔴** Flexible Printed Circuit (FPC) 🟢 Pressure/touch sensor Despite their large size, the earbud FPCs intricately fold into the housing of each earbud, bridging all of the components such as the batteries and drivers to the main PCBA. Each earbud contains 3 mics - you’ll spot *one* of these at the end of the FPC in the image above. The other two are positioned on the main PCB - more on that later… The touch sensor is what allows for pinch inputs from the user - allowing them to skip tracks, switch between noise cancellation modes, and adjust volume. ‎ **Circular Earbud Components** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-05-14/1715705346-701029-ig-16-9-4.jpg "banner") 🔴 11mm driver - Ceramic diaphragm 🟠 Driver rear with 4 vents 🟢 46 mAh earbud battery One of the biggest upgrades to Nothing Ear is the new ceramic driver. Rarely seen in audio products, the ceramic material is distinctly rigid, making it a great choice for delivering crisp highs. On the rear of the driver, you’ll see two additional vents, making a total of 4, to allow 10% more airflow within each bud compared to Ear (2). Each earbud also contains a 46 mAh battery, which is a noticeable improvement compared to the 33 mAh batteries in Ear (2). ‎ **Elements of the Earbud Stem** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-05-14/1715705346-902986-ig-16-9-5.jpg "banner") 🟢 Transparent stem shell 🔵 Antenna module 🟠 Printed Circuit Board Assembly (PCBA) The stems of Nothing’s audio products have maintained the same iconic silhouette since the ear (1). Here you see the main components of Nothing Ear that contribute to creating this shape. The words ‘Nothing Ear’ in the Ndot font are etched onto each transparent stem shell and are easily read when assembled on top of the black antenna module. ‎ **A Closer Look at the Earbud PCBAs** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-05-14/1715705347-319371-ig-16-9.jpg "banner") 🔵 Mic for voice/talk 🟢 Feedforward mic for ANC and ENC 🟡 Bluetooth audio SoC 🔴 Battery charge chip 🟠 Touch/press chip Above are the front and rear sides of our earbud PCBAs, featuring a series of chips, mics and 2 connectors for the FPCs and touch sensors. Together, the 3 mics and an AI-noise reduction algorithm detect a voice, enhance it, and filter out unwanted background noises in real time. ‎ **Inside the Ear Case** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-05-14/1715705346-467061-ig-16-9-3.jpg "banner") 🟢 500 mAh case battery 🟠 Case PCBA 🔵 Wireless charge coil The largest electronic component inside the charge case is the battery - Nothing Ear has a battery life that lasts 25% longer than Ear (2). The larger 500 mAh case battery and 46 mAh earbud battery mean a combined battery life of 40.5 hours with the case and 8.5 hours of non-stop playback on a single charge (with ANC off). Our case PCBA and charge coil are uniquely shaped to fit inside of our distinctive charge case design, more on that below. ‎ **Case PCBA** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-05-14/1715705346-35925-ig-16-9-1.jpg "banner") 🟢 Pairing button 🔵 USB-C port 🟠 Inductor 🟡 Charge chip Above is the PCBA from inside the Nothing Ear charge case, featuring the pairing button, USB-C charge port and all the logic and components required to safely charge the earbuds. ‎ **Elements of the Ear Case** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-05-14/1715705347-115169-ig-16-9-6.jpg "banner") Contributing to Nothing Ear's iconic appearance is the transparent charge case with its aesthetically pleasing unibody design; it’s made from a pressure resistant PU material, with 89% light transmission for a glass-like appearance. The electronic case components seen in the other images are all housed within the white central housing which is composed of two parts. On the bottom right you see a series of magnets, the pairing button, case hinge and coloured dots which indicate where each bud should be placed. --- We hope you enjoyed diving into Nothing Ear's improved internals! We had a lot of fun working on this project, learning about each part in more detail and composing the shots alongside our photographer. **Giveaway [Now Closed]** > If you'd like to win a pair of Nothing Ear in the colour of your choice, like this post and comment below your answer to this question: which part of the Nothing Ear teardown made you appreciate the engineering behind these earbuds? > > T&Cs: the giveaway will end on May 28th at 12pm BST! 3 winners who have liked and commented on the post will be selected at random, and given 1x pair of Nothing Ear in the colour of their choice (subject to availability), 1x Entei plushie, and 1x Nothing pen and notebook.

I am fascinated by the earbud PCBAs, those things not only have a pleasantly looking shape, but also pack so much tech inside them and make use of every mm² the circuit board has to offer in a satisfying way.

Rob ⚡️ I really like how much small parts they use inside the case which other manufactures wouldn’t because they’re only for design and also how much technology they were able to fit inside those buds is amazing! There are no better buds!

dranoel

Rob ⚡️ Im absolutely astonished by the way all the components fit together as a whole. Its so interesting to see all the little dents which are carefully placed to make room for a chip on another pcba, only so that the system as a whole is able to fitted inside such a tiny covering. As an architecture student, this “form follows function” approach is very inspiring.

ShahanxD

The circular components, notably the ceramic material upgrade and the extra push to adjust additional vents allowing more airflow, is what makes me appreciate the Team’s persistence to achieve more. Great job! Oh and this is the most beautiful teardown I’ve seen in a while, thanks!

CharlesChikanya

Rob ⚡️ honestly speaking i love the design of the case and the buds,their simple and yet they fuel my curiosity.They also make me want to learn more about them and the vibe they seem to have👻.Also you guys always give us nice details about your product which is super 😉😉

Not many companies are able to optimize the interior spaces.

Nothing instead is among the best in this, and we notice it since Nothing Phone 1; the optimization and management of spaces is even more evident analyzing the Nothing Ear. I was surprised how many components were inside one of the headphones. I thought they were less, or that they were arranged differently..!

Rob ⚡️ As an engineering student, I loved seeing the earbuds PCB A, and how those minuscule components drive such complex tasks. It was mind blowing, thanks for posting the tear down pictures!

thatguyinahat

Honestly I’m a massive fan of the case and the mechanics behind it. It turns an already great product into a stellar one that intertwines form & function so beautifully.

Tim

I appreciate the layering of the stem, especially as the PCB between the bud and the stem is very narrow and likely delicate but the layering creates a robust structure that doesn’t flex or feel fragile in any way.

Rob ⚡️

I loved the complexity of the parts made to look simple. Love the design!

ThanosB

The 46 mAh battery was the best (best not sound-related at least) improvement. Good job!

EdwardJun

Rob ⚡️ nothing product is awesome to be using in daily, I started to use nothing product since the nothing phone 1 and nothing ear stick lunch and catch my eye of the beautiful design, hope nothing will keep on improving in every and I will keep on supporting nothing

I love nothing

IgorMarcelino

I appreciate how even the case battery uses the nothing font, truly showing how meticulously designed and engineered theses earbuds are

NathanPress

Rob ⚡️ Im appreciate that there was thought, intention and inclusion of an iconic design, even on the breakdown down of the earbud stem. Shes that girl.

SIDDHARTHSingH_xpxiZ775S4

Rob ⚡️ the engineering around that cool circuit board is really amazing

BaseXPhotography

Rob ⚡️

Wow that is really cool to see!

I really appreciate the design theme of Ear.

My favourite part is seeing what the driver size is and the vents and didn’t know that earbuds needed vents.

It is also really cool to see the earbuds of Ear and see all the components of its existence.

Super cool thx Nothing

P.S I am looking out for the blue color of the Ear(a)😉

Rob ⚡️

The way everything fits in the transparent stem and still looks good is amazing

Elements of the ear man. The pure milk white colour kills me.

JulianColeman

Elements of the Ear Case 👌
