He loves the fit, the style, the color and the brand. I dont know if this is due to a slightly imperfect balance of the flywheel or simply due to some sort of harmonics with the belt drive, but while it is noticeable it doesnt really bother me. If 2 will work in tandem I will get another. Color was grwat But it is still maybe 1 full size smaller. I wish they were a little bit louder, but its still a great value. The 2nd one just came in. I purchased the Bose 700 NC which is the version that did not come with the pre-paired bluetooth dongle. I found that when switching from Hip-Hop to Metal, the earbuds struggled to keep up. Kauf habe ich nicht bereut.
