Bests & Worsts Reviews from Amazon

I have learned through numerous headphone purchases (mostly wasted) that buy headphones with your activity in mind. No headphone design is good for all body movement patterns, sound requirements, and weight profile. Sometimes you just have to but em and try em to see if they fit your activity listening requirements. I bought these headphones for running. Just for running, not for exercise or more broadly sports. I use other headphones for those other categories. I already use the Nike HJ020 Flight Sport headphones for running. I use other styles for other types of activities. In general, the behind the neck in-ear design (Nike and Senn.) are a good choice for running since they stay secure while being lightweight and have a low profile. However, the design is not functional for lifting weights or seated listening. The neck band pushes against the bench/chair and comes out while hurting your ears. Also, I do not find the design comfortable on my ears for general listening. I much prefer using the various Sony earbud styles for general listening. The Sennheiser PMX70 is very similar in design to the Nike headphones. Here are the differences: - the cord comes out the neckband on the Nike and the left front side on the Senn. Coming out the neck is less intrusive to your face but puts a little weight on the neckband. Nike + - the neckband comes over the ears for the Senn. and straight to the neck for the Nike. For the Senn., the earband puts pressure on the outside of the ear unless you push it behing the ear. Either way, it a little snug on the ear. Nike + - The Senn. are a little heavier then the Nike. Nike + - The Senn. behind the ear design and stiffer neckband make the headphone a more secure albeit snug fit. Senn. + - The Senn. is more stylish but a more visible profile (depends on what you want others to see) - The Senn. sound is superior, but not detectable during running. Senn+ For me, I am sticking with my Nike headphones for running. I am always on the lookout for new, better headphones. For running, The Sennheiser PMX70 is new but not better.
