This $129 Shoulder Bag Lets You Play Music Without Opening It

An innovative music bag by Teenage Engineering that blends tech design and everyday practicality.

A Tech Bag That Breaks the Mold

There’s something downright mesmerizing about a tech company that obsesses over the little things. While most brands slap their logos on generic nylon bags and call it a day, Teenage Engineering OB-4 Magic Radio portable speaker takes the opposite route. Their Field OB-4 shoulder bag isn’t just a carry case; it’s a thoughtfully designed companion for their OB-4 Magic Radio. Imagine a bag that lets you play music without even opening it. That’s exactly what Teenage Engineering has pulled off with this clever $129 shoulder bag.

Designed to Use, Not Just Carry

Most bags are all about protection and concealment. The Field OB-4 bag flips that idea by giving you access to your gear while it’s still inside. The mesh front panel is the star here, allowing sound to flow freely from the OB-4 Magic Radio speaker without unzipping a thing. This is more than just a neat trick—it’s a glimpse into how product design can solve real-life user needs without compromise.

Designer: Teenage Engineering

Built Like Outdoor Gear, Ready for City Life

The bag’s materials speak volumes about Teenage Engineering’s priorities. It’s made from tear- and abrasion-resistant nylon 66, treated with a fire retardant, and backed by a PU coating to repel water. The black version boasts a 1500 mm water resistance rating, while the white hits 3000 mm. These aren’t just fancy specs—they’re the kind of rugged fabric you’d expect on serious hiking gear, repurposed for urban adventures like subway rides and café hangs.

Thoughtful Compartments for Every Accessory

The Field OB-4 isn’t just about the main compartment. It features a roll-down covered opening that adjusts capacity based on what you’re carrying. Inside, there’s a snug pocket for your everyday essentials—think keys, wallet, or that tangled mess of earbuds you keep promising to sort. The back pocket is custom-sized with hook-and-loop closure, tailored specifically for cables and the Ortho remote.

This isn’t generic storage. Teenage Engineering measured their own accessories and built the bag around them. You can wear it crossbody for hands-free city strolling or grab the sturdy side handle for hand-carry mode. This adaptability is key—whether you’re navigating crowds or chilling at a café, the bag flexes with your day.

More Than Merchandise: A Design Philosophy

Here’s where Teenage Engineering’s ethos shines through. Making a bag like this isn’t about slapping a logo on an accessory and calling it a day. It’s an extension of their design philosophy, rooted in precision and joy, much like their iconic OP-1 synthesizer.

Their style—a blend of Dieter Rams’ minimalism and Nintendo’s playful charm—either grabs you instantly or leaves you cold. The Field OB-4 bag comes in classic black or white, sticking to that signature minimalist palette. Custom aluminum hardware and smooth YKK EXCELLA zippers elevate the experience, using components found in high-end luggage. These are the details you only appreciate once you’ve dealt with cheap alternatives.

Is It Essential? Not Quite. But It’s Special.

You could carry the OB-4 Magic Radio portable speaker in any run-of-the-mill shoulder bag, sure. But then you'd miss out on the mesh panel’s unique convenience, the perfectly sized pockets, and that wonderful feeling of seamless design integration. Teenage Engineering exists in a niche where consumer electronics become design objects. Their products might cost more than alternatives, but that's because they sell coherence, not just functionality.

The Field OB-4 shoulder bag continues that tradition. It’s aimed at those who already love Teenage Engineering’s ecosystem and appreciate the sweat equity in details most never ask for but are glad to have.

Premium Pricing, Premium Audience

At $129, the Field OB-4 is a premium accessory, not an impulse buy. It’s crafted for the crowd that values design specificity over generic use. This is the same audience that chose the OB-4 speaker itself over cheaper Bluetooth alternatives because they wanted personality and thoughtful design.

Whether this bag is a must-have depends on your values: if you prize tailored function and design coherence, it’s exactly what you’ve been waiting for. For everyone else, it serves as a fascinating example of how far product design can go when shortcuts are off the table.

Wrapping It Up: Would You Carry Your Music?

It’s not every day a simple bag gets you rethinking how you carry your tech. Teenage Engineering’s Field OB-4 shoulder bag reminds us what happens when design is more than skin deep — when it’s about enhancing everyday moments. So, would you go for a bag that’s as much about playing music as keeping it safe? Let us know your thoughts!
