soundcore AeroFit 2

45%of 51 owners recommend
45% recommend · 20% neutral · 35% don't
Owners praise
  • Exceptionally comfortable, lightweight open-ear fit — many owners say they forget they're wearing them and have even fallen asleep in them by accident
  • Sound quality that beats other open-ear/bone-conduction options like Shokz, clip-style buds, and bone conduction headphones, with clear vocals
  • Stable multi-device connection and reliable performance for hours-long work calls (Teams, etc.) without needing to repeat yourself
Owners complain about
  • Charging and connection failures over time — earbuds dying, one side not charging/pairing, or units needing to be reset repeatedly — leading some owners through two or three replacement units within a year
  • Touch controls feel finicky or janky, and the angled fit makes it easy to trigger the touch sensor by accident
  • Bass response is thin compared to sealed in-ear buds, an inherent tradeoff of the open-ear design
