These things are junk. In the package, seemed okay. Get them out, you're in for a surprise. The "ear hooks" are a pain in the ass to get adjusted over the ear. I have no clue how they actually sound, and have no intentions of finding out. Don't care. Body Glove makes things out of rubbery flexible stuff, usually. These hooks are more of a plastic, like the ends of eyeglasses. Because of that, you have to fiddle around and get things Just Right, or they're not gonna stay put. And the hooks are supposed to be removable, so you can swap colors, if you're a fashionista. Don't ask me how to get them off. (or I would've kept them) And don't look for them on [...], because apparently, Body Glove doesn't know they manufacture this product. It doesn't exist on their website.I figured they'd make a good solid product for athletic purposes, so that would wear well for my normal usage. I'm taking them back, and gonna get a set of ANYTHING else, like skullcandy or whatever. I'm not a real audiophile, so as long as they play, I'll be happy. But if I can't get the damn things on my head 1-2-3, they obviously aren't worth squat. (to me).These were supposed to be a simple replacement of my factory Sony set, from a Walkman MP3 player. Nothing special. (although, the Sony's WERE special, the sound was decent, and the whole package lasted over two years) If I was gonna hook to my phone, I'd use Bluetooth. This is just an extra kit, for when I don't want my smartphone getting exposed to the wear and tear of hiking and biking, beach and dirty rugged stuff.I mainly came here for a review explaining how to get the earhooks off. There are a variety of models, 2.5 and 3.5, with and w/o phone mic and pause button. So, regardless of those specs, the ear pieces are the same. I wouldn't keep them if they were free, and I certainly wouldn't buy them knowing what I now know. And they're a joke, so back they go. I'm glad I kept the receipt.I should've known better when I couldn't find the tech specs on the package, regarding the Db and freq output, and all that gibberish. I now realize the only thing Body Glove was selling was its brand logo, and the mechanical and technical aspects of its product were considered irrelevant by the manufacturer.
