Here at CES in Las Vegas, I am pleased to test the new Aftershokz model. There are a number of improvements. The electronics have been moved from the back of the headband to the sides giving it a more balanced feel. The weight is the same but I find that it squeezes my temples less and the sound is still good. The controls are on the right part of the band. There is no longer a button on the right ear tip. The antenna has been moved forward so the unit does not drop out as much as the previous model. There is better isolation so the sound linkage is much less. The sound is different but I haven't tried them in enough different situations to know just how different. For phone calls and using Voiceover, they are good. They expect to be shipping in March. I'll comment more after I have had time to test thoroughly.
