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.

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