The history of recorded music has many examples of songs that offer life advice. The Rolling Stones said that you can’t always get what you want; Christina Aguilera reminded us that we’re beautiful no matter what they say; and Hanson famously warned that in an mmmbop they're gone – but Amazfit’s PowerBuds Pro (€130) are the first earphones we’ve seen that dish out their own tips. These IP55-rated true wireless buds can detect how you’re sitting and if there’s not been enough movement in your cervical spine (seven of the vertebrae in your neck) they’ll play a tune to remind you to stay active. There’s also a heart rate monitor onboard, and they can track your time, speed, distance, and calories burned when you go walking, running or cycling. Chuck in active noise-cancelling (with a Thru Mode that lets a little bit of the outside world in as required) and up to 30 hours of listening time with the charging case, and picking up a pair starts to sound like some pretty solid life advice.
