Frequently asked questions

Are the Fairbuds 2 PFAS-free?

We pioneered the use of PFAS-free and more than 70% post-consumer recycled plastics—keeping persistent chemicals off your skin and choosing smarter materials for the planet.

Is production carbon neutral or renewable-energy powered?

The production of the Fairbuds 2 uses 100% renewable energy.

What does e-waste neutral actually mean?

For every Fairbuds 2 unit sold, Fairphone collects and recycles an equivalent weight of e-waste elsewhere, offsetting the product's own eventual waste footprint.

Does not using glue impact the water resistance of the Fairbuds 2?

No. Water resistance is maintained through other sealing methods rather than glued-in batteries.
