Why choose the C40i?
If you’re looking for earbuds that keep you connected with your surroundings (e.g., runners, cyclists, outdoor workers, office multitaskers) rather than totally block out the world, the C40i is a strong pick. Reviewers found the sound quality “remarkably good” for an open-ear design. Tom's Guide+1

⚠️ A few caveats:

• Because they are open-ear, you’ll still hear surrounding noise and sound leakage may occur (others may hear your audio). Tom's Guide

• Battery life is modest compared to some in-ear sealed buds, so depending on usage you may need to recharge more often. TechRadar

• They do not have active noise cancellation (ANC) — they are not designed to isolate you from outside sound.
