Awesome, but I'm skeptical. Not because it's Fairphone, but because previous bad experiences.
I bought Sony buds, after reading loads of reviews and those were the best! They cost me around 300 and what I got was just shit.
I (still) own a number of lg 800 Bluetooth headsets (those with a thing you wear around your neck) that cost me 50 bucks each, that have better audio quality, louder audio, better noise cancellation, are more comfortable, and after over 4 years still have a battery life of around 10 hours where those huge ass Sony ones cut out new after like 3-4 hours and they died after 1,5 years. I think those wearable bugs are just too small to be any good at all.
