Sound quality #1
My number 1 priority for ear buds was sound quality. Comfort was number 2. I've spent the last several days listening to various types of music on these and trying to give them on objective listen. I have compared them to some other ear buds and headphones as well. When I listened to the album 3D by Kraftwerk I was blown away. The 3 dimensional sound moving up and down and side to side was incredible. The bass is nice - not loud and over bearing, but present. The miss and highs were also just perfect, allowing me to hear subtleties that I have not heard in the music before. These are definitely the best sounding ear buds or headphones I've ever owned.
As far as comfort, definitely much more comfortable then the apple AirPods (and again, sound quality far superior to Apple). I like to sleep with my ear buds in. I can't keep them in the whole night due to discomfort, but I've never had a pair of ear buds where I have been able to. Perhaps they could round the edges of the outer rectangular piece as well.
Overall I'm truly blown away by these and am sold! Thanks for your amazing product.
