The verdict

While its new adjustable design is a welcome upgrade over the one-size-fits-all approach of the original AeroFit open-ear earbuds, the AeroFit 2 are not immune to the same sound quality compromises that come with the open-ear design. That said, if you're testing the waters of the open-ear world, they're one of the more affordable options to consider.
