This is my third Anker headphone purchase (Life 3i, AeroFit 1 and now these) and each has been an enormous improvement over the last ones, which have all been very well-loved. I also own a pair of Shokz Openfit Airs, AfterShockz bone conduction headphones, and a couple knock off brands of open ear headphones. For clarity I will only compare these to the AeroFit 1’s and the Shockz Openfits.1) Weight: One of my favorite things about my Shockz is how light they are, and this pair matches that quite well. The 1’s would start to annoy my ears after a while due to their weight. I can’t even tell that these 2’s are on.2) Fit: The 2’s fit is amazing and the ability to adjust them makes all the difference. The 1’s were a bit bulky and would fall off if I needed to adjust my hair around my ears, and a drop onto rocks last weekend pretty much gave the right one a death knell. I love the Shockz’ fit. The 2’s are comparable to the Shockz. They aren’t budging. I also sleep with headphones, and these were very comfortable when I was on my side.3) Battery life and quick charge are great. The 1’s battery life was what made them win over the Shokz, even though I had liked the Shockz’ fit and weight more. I listen to stuff in the background a lot, so everything gets a lot of use. The six-hour life of the Shockz just wasn’t enough, and they would die even if they weren’t being used. The 1’s would be the energizer battery and just keep going, I would often get a good day and a half out of them before needing to charge. These arrived yesterday afternoon at 80% charge and 20 hours later I only had to charge them for thirty minutes to have them at 100%.4) Cost: I got these on sale for $100 and that seems to be a good price point for great quality and features but not going to break the bank.5) Sound: The 1’s could be a bit tinny, these produce a nice, rich sound similar to the higher-cost Shokz.6) Controls: The app makes all the difference in functionality for me. Being able to change how many taps to play/pause puts Anker leaps and bounds above Shockz.
