With headphones I tend to focus on what they are intended to do. In this case, these are for working out and so there will be sacrifices in order to make them sweatproof, water resistant, etc.

Great sound with great bass, excellent build and the white matches with the white i gear; Fit is very unique to each person but they seem to fit great and they stay on the ear during workouts

A bit pricey but you get what you pay for

I don't have any headphones to compare them to, as these are some of my first good quality headphones. They sound great, they're pretty comfortable, if you wear them around the house, or just walking around, they stay nicely in your ear, however if you do something that makes you sweat, they don't...

Good sound; cheap

Bad build; headphone easily detaches from plastic arm; easily comes out when sweating (Probably fixable with thirdparty tips

Awesome sound quality but the behind-the-ear piece keeps falling out when I'm jogging, and I cannot adjust it to my satisfaction. It's a minor annoyance.

After extensively researching my options I purchased these headphones through JLP. The sound quality is really impressive, and the design appealing, but no amount of fidgeting would make them stay put in my ears.

Right earphone death after 5 months I got this earphones in December 2015. Usually I used while running and right earphone stop sound on April 2016. I'm casual runner (run 2 or 3 times per week 5K = 30min aprox).

earphones should have great or even decent sound and these were awful. very hollow and tinny sounding. the german brand is supposed to be higher end , the $80. price was extremely disappointing. my older phillips buds from Target for $15.

over the ear clips were secure and comfortable

sound

after 10 mins into 10k runs crackling , volume changing up and down ended up taking them out gutted threw away packageing

,

Great and comfortable fit; however, only after a few weeks the right ear piece stopped receiving sound.
