I got it and delivered in timely manner.
I am very excited as previous headphones fall off constantly.
I ran long distance, and in fact I use this one for a marathon.
I don't know if anyone experience this before, but when you are running for 4 hours, after that I feel the pressure pushing through my ears. So, I thought you need an alternate earphone after 4 hours? Or take it off and sing to yourself.
While I don't usually run 4 hours straight with this headphone daily, an h0ur workout does fine. Even going through fast hills and an speeding with my mountain bike.
Sound quality is great - not perfect but around 7/10. This ain't high end, so this meet my expectation. I like the volume control that comes with it. I like the sleep design....trust me, if you run for continuous 4 hours, the small, lightweight design is a perfect plus.
The cord is long enough - it fits in the pocket of my cargo pants.
Overall, I'd say 4/5, because of the pressure I felt as I wore it for a long period of time.
Lightweight, good price, great sound quality - I recommend this to anyone.
Thanks amazon for the timely delivery.
