We go hands-on with Shokz's upgraded true-wireless OpenFit 2 open earbuds that use its air-conduction speaker technology.

The OpenFit 2 — available in black or beige — keep the same basic formula of the original, but use a slightly tighter curve on the earhook, with inner surfaces covered in Shokz’s Ultra-Soft Silicone 2.0. Add to that a new flexible nickel-titanium alloy, Shokz says the new earbuds should be both more comfortable and more secure.

The second-generation model has a tweeter and woofer in each ear and a multifunction button for fewer accidental touches.
