I have both right now. There are pros and cons for both so it depends what is important to you. Quiet Comfort 1 versus 2… Great Noise canceling - I don’t notice a difference between them, they are both the best earbuds I have found for noise canceling and I have tried all the high end earbuds Ear fit is customizable - both 1 and 2 fit my ears fine, but not my husband’s ears. He couldn’t wear them without them falling out. He end up buying the Sport version. (They provide 3 wing size options so you can pick the best fit for your ears but ver 2 actually let’s you choose the size for both the wing and also the earbud piece, so you can combine them however you like) Case size - Version 1 has a big case and they don’t fit great in pockets or small purses. Version 2 case is closer to the iPad Pro size. Also note that the version 2 earbuds are smaller in your ears. I am fine with both sizes and don’t prefer one over the other in regards to earbud size. Battery life - From what I researched, version 2 has a longer charge but I can use my version 1 almost the entire day with noise canceling and then put them back in the case to charge. I charge the case 3 times a week. I haven’t tried doing this with version 2 yet. Wireless Charging - version 1 case can charge wirelessly but version 2 does not. This was the DEAL BREAKER for me. I love the smaller case for version 2 but I love more just laying my devices on a charging pad and not having to go find the cord and plug them in. I am returning the version 2 I got on Black Friday for $250. I will wait for their next version that adds wireless charging. Answer from Admirable-Fly-8252 on reddit.com
