Meh. I may wait a while for another generation or two. I have the model that was released right before this:

Was not impressed with the sound quality. Compared to my Sony Extra Bass Over Ears, these were lacking greatly in sound quality. I understand a lot had to be sacrificed for the true wireless too work, but I'm cautious to see how much of a sound quality difference these will be compared to my current ones.
Same goes with the noise canceling. My over ear Sony headphones had better noise canceling than my Sony true wireless HOWEVER, the ambient sound feature is great, which allows you too hear outside elements while using the headphones while in the street or in the store. Also, when you answer calls on this thing, only the left side works for calls.
Because of these things, and the fact they do not handle high resolution audio well, these have become my default gym headphones, which they are perfect for. My gym music is from Spotify, so the quality is low to begin with so it's fine with these headphones. Also I have dreads, so over the ears are awful for me, and these are so small I can throw them in a backbag easily and always be ready to use.
Another issue, is that there would be random connection issues. Either the right side would go out and come back in or the sound would crack randomly. They also had a big issue with syncing with video (which my Sony Bluetooth speaker still has issues with) but it patched later to fix the problem.
I have no idea what new tech they were able to fit into the new model but I would definitely wait for many reviews before I would even think about upgrading.
