I bought them for my kids to use with there laptops for school and they work perfectly. But, its sturdy and holds all my clothes. This is the first time Im able to view my sleep cycle and track my deep and light sleep patterns. The longest lasting was a Jawbone and the other was a cheap off brand that I bought off Amazon that lasted just a few months and did not have that great noise cancellation. Im not spending another $25 for these headphones to maybe work. However, the price tag is really out there. These are small speakers so theyre not going to be able to do everything. 5? diameter, not 3. It appears that the small bud tips will work for me and the real test will come on Wednesday at the gym on the treadmill, I have a very hard time finding a bud that stays in my ear so it blocks out all the other gym racket. Seriously, when they finally broke (after nearly 2 years of use) I bought a pair of Skullcandy Lowriders (which I payed liked $23 for) because I thought they would be good but the bass on them is just a bunch of thuds compared to these things.
