Shokz has made improvements to comfort, volume, battery, and touch controls. Unfortunately, the sound quality is a little more muddy than I’d like.

Improved comfort, double the drivers, better Bluetooth and much longer battery life can be found on Shokz's OpenFit 2 earbuds.

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.
