The best headshot I bought ever. I like the idea of 2 balanced armature and 2 dynamic drivers in the ZS5 MUCH MORE than the 4 BA and 1 DD on the ZS 10. These are perfect for me! I am writing this off as a faulty bud and ordering a new pair. I use a smaller phone (iPhone 5s), and the phone stayed in place while riding over some of very rough (deteriorating) roads. wore these as the mother of the bride. But its a little harder to reduce the pouch the older I get but once I hit that mark its healthy eating and juicing , so every 4 to 5 years I have to hit it harder and the waist trainer is my help mate lol. Not tinny and not too much bass (although I do tend to the bass-heavier side of the fence). Theyre very smooth/slippery plastic with all rounded edges. Great product, easy to use, worked well on my Jeep allowing me to transport my kayak when I wanted to without the need of a permanent roof rack.
