I have used Bose QuietComfort 15 noise cancelling headphones when I travel for the past 7 or 8 years or so, and I love them. Despite how comfortable they are to wear, I find they are a bit bulky to transport, so I have started looking at the newer QuietComfort 20i in-ear model. I am curious if anyone here has transitioned from the 15 to the 20, and if so, do you have positive or negative feedback you would be willing to share.
If there is already a thread about this, I would be grateful for a link instead. I found a thread about people looking at alternative cases for their 15s, but I could not find one directly comparing the 2 models...though it is possible I did not use the right search combination.
ETA: My primary use for these headphones is for their noise blocking capabilities. I am not as concerned about having perfect music sound quality.
