Pros

  • Bone-conduction technology works well
  • A lot of improvement over the first-gen models

Cons

  • Sound quality is still poor-to-bad
  • Not ideal for quiet environments

At A Glance

While these bone-conduction headphones are great for runners and cyclists, they're still a bit lacking for true audiophiles—and not great for use in quieter environments.
