And this time we’re taking a look inside our latest product, Ear (open) - our first open wearable stereo (OWS) product. We understand that this is a new device category for many of you, so we’re looking forward to breaking down how they work and taking a look at the internals. We entered the OWS category to bring our customers great audio whilst still maintaining the ability to hear everything around them. Whether it's the birds singing or a car coming around the corner, there are a wide range of use cases where this form factor can enhance day-to-day life. Let’s take a look at what makes this all possible… ‎ **The Buds and Driver** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-10-14/1728900694-798763-ear-open-16x9-2-2.jpg "banner") Fully assembled at 8.1g per bud, Ear (open) offers an extra secure, weightless fit that can withstand everything from office work to extreme sports. Ear (open) is tilted at 50 degrees to position the speaker directly over your ear and at the point of most comfort. If we remove the ear hook and bud housing, we can get a good look at the Ear (open)’s driver (🔵), the biggest so far in any Nothing product with a 14.2mm diaphragm. The patent-pending diaphragm is uniquely shaped and corrugated – moving the torus inward and changing its profile. This reduces distortion and deepens the sound of low frequencies meaning bass-heavy tracks hit like they should. There is also a titanium coating on the surface which is lightweight and robust - this silver-hued top layer helps to reproduce crisp high-frequency notes with great accuracy. The driver is attached to a small flexible printed circuit (FPC) which features pogo pins for charging, wires leading away to the battery and one of the two mics (🟡) found in each bud. On the bud housing in the middle, we spot a unique L-shaped pickup channel (🔴), which delivers sound into the talk mic on the FPC helping to mitigate wind noise. ‎ **Transparent Housing** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-10-14/1728900718-188806-ear-open-16x9-3-2.jpg "banner") The second of the two mics, the feedforward mic (🔴), can be found on a small FPC inside the clear bud housing; this one is positioned on its side to avoid direct wind. This FPC also features the touch sensor (🔵) which allows for a range of gesture controls, all managed via the Nothing X companion app. On the *outside* of the bud housing, you’ll also spot the long mesh (🟡) - Ear (open) is engineered with a ***Sound Seal System*** and directional speakers to minimise sound leakage for a private listening experience. Reverse sound waves are generated at the rear acoustic ports, which are then superimposed on the sound from the inward acoustic ports. This effectively means sound waves are cancelled out, ensuring precise audio transmission from Ear (open) into the users ear. ‎ **Bud PCBA and Antenna** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-10-14/1728897089-157815-ear-open-16x9-4.jpg "banner") In the image above, we get a look at Ear (open)'s printed circuit board assemblies (PCBAs) (🔴), the heart of each earbud. This is where the two FPC’s mentioned above connect to, bringing all of the electronic components together. The PCBA’s also feature a series of chips to manage things like Bluetooth and battery charging. Stacked on top of each PCBA is an antenna assembly (🔵). On the back you’ll spot a brass-coloured area (🟡) which is what takes electromagnetic waves to/from the PCBA. If you look closely you can see how a thin FPC wraps around the front of the antenna assembly to help transmit and receive electromagnetic energy. On the top we have our iconic red and white dot decos to help quickly identify which bud is which. ‎ **Ear Hook and Batteries** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-10-14/1728896896-735681-ear-open-16x9-5.jpg "banner") The ear hook (🔴) is what gives Ear (open) its unique silhouette - it's designed to be perfectly balanced and secure, bringing that all important weightless feeling when in use. They have a nickel-titanium wire structure within that makes them both flexible and resilient. On the outside is a white, skin-kind silicone material which contributes to a comfortable wearing experience. Travelling through each ear hook is a pair of wires which links each battery to the FPCAs mentioned earlier. These wires need to be pulled through each ear hook using a nylon wire during assembly. At the end, each battery (🟡) comes in at 64 mAh allowing for up to 8 hrs of audio playback. The batteries are protected and securely held in place by a pleasing aluminium cap (🔵). ‎ **Charge Case Internals** ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2024-10-14/1728896871-923897-ear-open-16x9-6.jpg "banner") At 19mm thin, Ear (open) has one of the slimmest charge cases in the OWS category - despite this, you’ll find a number of components neatly arranged inside that allow for quick charging and convenient pairing. To keep the buds topped up, the charge case features a 635 mAh battery (🔴) - combining this with the buds batteries, you can achieve up to 30 hrs of audio playback. The charge case delivers power to the buds through pogo pins, one pair on the FPCA on the right (🟡), the other pair on the PCB on the left (🔵). In the middle of the FPCA, you’ll spot the pairing button (🟢) and just above, the case LED charge and pairing indicator which gets diffused and directed out of the case via the plastic piece above. ‎ **Well there we have it!

Rob ⚡️ I had no idea about the PCBAs. Got to know few information about that.

Simon

This was my first time knowing what exactly is inside hardware like the Ear (open). I didn’t even know what batteries looked like for devices like these before this post so kudos to the team for that. Excited for the path ahead for Nothing.

Rob ⚡️ I’ve never really been a fan of open type earphones because I love the bass that in ear gives but looking at reviews of it, it seems to be really good and still gives a good bass. The other thing I like is the hook, which sits on top of the ear and prevents it from dropping which I struggle with most in ear since my ear gets oily very easily.

Rob ⚡️ I love the design of every nothing product, it’s uniqueness.

Here it’s the hook design which gives it a different look to other open earbuds

federico_calvone

Rob ⚡️ Wow I really like to look inside this kind of tech product. When I see something cool I usually look up online teardown videos to look how they are on the inside. My favorite products are the ones that look good both outside and inside!

I respect Nothing for proudly showing the insides of their products, both with transparent plastic and teardowns. I’ll take inspiration from this if I’ll design something of my own!

Rob ⚡️

The thing I find most interesting is the sound sealing system, allowing for a private listening experience, even though it is an OWS.

Perhaps, with some more R&D, Nothing may even develop an Ear open 2 with ANC (similar to Apples airpods 4 with ANC). Who knows what the future holds

SyedNabi

I love how Ear (open) brings a fresh take on open wearable stereo technology. Learning about the unique 14.2mm driver design and how it balances deep bass with high-frequency clarity was insightful. Plus, the transparent housing and thoughtful placement of components to reduce wind noise shows great attention to detail. Looking forward to experiencing seamless audio without losing awareness of my surroundings.

Rob ⚡️ Really interesting to see the inside of the Ear(open), I didn’t know there were such big circuit boards in the earbuds, always thought it wouldbe a really small chip. Thanks for showing us the inside of the Ear(open)!

Donnacha

Wow, the magnet placement is so clever! 🔥🔥🔥

segamanxero

Reminds me of how hearing aids are constructed, and are like this designed with long term use in mind.

Very cool what Nothing has done here with the Ear Open.

GabrieleMonni

Rob ⚡️ The battery position is very smart

PavanSagar

Rob ⚡️ I was looking for the transparent side where Nothing does it usual for every product, and then here it is hiding underneath-the transparent housing(everything’s good there), that’s all it is.

LasseHelbling

Rob ⚡️

I find that the position of the batteries in the buds very smart for weight distribution

Albi27

in future models i would like too see more pcbs and internal parts throught the transparent parts, specially on the case. there are a lot of beautyfull parts covered.

MikeSalman

Every Good product nothing

AlexisGarza

Rob ⚡️ This is what got me so excited and had me looking forward to get them:

Ear (open) is engineered with a Sound Seal System and directional speakers to minimize sound leakage for a private listening experience, and the best part is that with the reverse sound waves clashing with the sound waves are cancelled out, ensuring precise audio transmission from Ear (open) into the users ear.

That’s a remarkable feat!

Rob ⚡️ as always, I love these insights! I didn’t realise the driver was the biggest so far, it’s always so exciting to see how much can be packed into such a small device and how transparency really plays with the design!

AshmitDandapat

Rob ⚡️ The lightweight construction and ergonomic shape aim for comfort during extended wear. Overall, it merges form and function, making a bold statement in the crowded audio market.

Adwekin

I need try this before I make finale decision if I’ll go for it or not. It Is not cheep at all…

ChrisConH

Rob ⚡️ was waiting to see more info about the diaphragm. Amazing guys, as always. As Carl said, u guys are slowly creating your own tech and not only integrating other’s tech
