Most wireless headphones are treated like sealed gadgets: when the battery weakens or a key component ages, replacement often means buying a whole new set. Fairphone’s repair-first philosophy pushes against that pattern by treating headphones more like maintainable equipment. One of the most interesting details in its newer Fairbuds XL update is that a major performance-related part can be swapped into older units, reducing the need for a full replacement.
What “upgradeable” headphones actually means
In consumer audio, “upgrade” usually means changing EQ settings, switching ear pads, or buying a new model. Modular hardware takes a different angle: it treats core parts as serviceable units that can be replaced independently. That can include the headband cushion, ear pads, charging port, buttons, microphones, and—most importantly for longevity—the battery.
The notable twist here is that you can improve a key performance component of a newer model and install it into an older one, which is a rare idea in mainstream wireless headphones. Instead of “new model or nothing,” it offers an in-between option: keep what you own, but refresh the part that drives a big chunk of the listening experience.

The part that matters most for sound
For headphones, the driver units (the components that convert electrical signals into sound) are a big lever for how a product performs. While comfort, sealing, and tuning matter too, drivers are one of the most meaningful “hardware-level” contributors to changes people notice.
The headline idea: newer driver units can be installed into older Fairbuds XL units. That’s significant because it treats sound quality improvements as something you can adopt without discarding the entire device.
| Scenario | What you change | What stays the same | Why it matters |
|---|---|---|---|
| Keep the older model as-is | Nothing | All parts | Lowest cost, no work, but no hardware refresh |
| Upgrade only the driver units | Drivers | Shell, controls, headband, most internals | Targets sound improvements without full replacement |
| Buy the newer model | Everything | Nothing | Most straightforward, but creates a redundant older unit |
This kind of cross-compatibility is also a practical “stress test” of whether modularity is real. If parts remain interchangeable across generations, the ecosystem can become more than a one-time marketing label.
Why a replaceable battery changes the long-term math
Wireless headphones live and die by battery health. Even if everything else works, a degraded battery can make an otherwise fine device feel unreliable. In many models, battery replacement is difficult enough that people treat the entire product as disposable.
A replaceable battery shifts the ownership curve: instead of “best performance early, then gradual decline,” you can potentially reset usability by swapping a single part. Over multiple years, that can matter more than minor feature additions.
Repairability claims are easy to say and harder to prove. If you want a general reference point for what repairability looks like in practice, iFixit’s guides and scoring discussions are a helpful starting place: iFixit.
Replaceable parts do not automatically guarantee lower total cost or lower environmental impact for every buyer. The real outcome depends on part pricing, availability over time, and whether people actually repair rather than replace.
Tradeoffs to keep in mind
Modular design isn’t a free win. It can introduce compromises and practical questions you should consider before assuming it is “always better.”
- Parts availability: An upgrade path only works if parts are stocked for long enough, in the regions where people own the product.
- Cost structure: If upgrade modules are priced too close to a full replacement, many buyers will still replace.
- Complexity and confidence: Even simple repairs can feel intimidating. Clear instructions and easy access to tools matter.
- Warranty and support policies: User-servicing is strongest when it is explicitly supported (and doesn’t quietly penalize you).
- Performance expectations: Upgrading one part can improve one dimension, but it doesn’t transform every aspect of a product.
In other words, modular headphones can be a smarter ownership model, but they still rely on execution details: consistent parts supply, transparent documentation, and sensible pricing.
A practical checklist for evaluating modular audio gear
If you are comparing “repairable” or “modular” headphones (or any electronics), a short checklist can help separate durable design from surface-level claims:
| Question to ask | What to look for | Why it matters |
|---|---|---|
| Which parts are replaceable? | Battery, drivers, charging port, ear pads, microphones, controls | Shows whether modularity targets real failure points |
| Are parts sold separately? | Clear storefront listings and long-term availability | Modularity without parts access is mostly theoretical |
| Are repairs realistic at home? | Simple steps, common tools, clear instructions | Determines whether most owners will actually repair |
| Is there cross-generation compatibility? | New parts fitting older models | Signals a longer-lived ecosystem |
| What happens to the “old” parts? | Recycling options, refurbishment, reuse guidance | Reduces waste shifting rather than waste reduction |

Why this matters beyond one product line
The biggest impact of modular headphones isn’t only the feature set of a single release. It’s the idea that a consumer device can be improved and maintained over time, rather than replaced on a fixed schedule.
If more companies adopt interchangeable parts—especially for batteries and performance-critical components—buyers could gain: more control over longevity, more predictable upkeep costs, and fewer “perfectly fine except for one failing part” retirements.
At the same time, modularity should be evaluated with healthy skepticism. The concept is promising, but the outcome depends on how long parts stay available, whether pricing encourages repairs, and whether the repair experience is actually approachable.
Key takeaways
Fairphone’s approach highlights a rare consumer-electronics pathway: upgrade a meaningful hardware component without replacing the entire product. For headphones, where battery aging and incremental sound improvements often push people toward a new purchase, cross-compatible modular parts can be a practical alternative.
The idea is not a universal solution, and it won’t suit every buyer. But it provides a useful model for thinking about ownership: not just “what does it do today,” but “how easy is it to keep doing that two, three, or five years from now.”
