Lenovo A660 Waterproof Dual-Core 1GHz Dual 4 Deal

El Cid: The fit of these is nice, and the sound is decent for a water resistant / workout headset. The problem is that any time I turn my head to look for traffic (e.g. put my body between the phone and the headset), the bluetooth signal drops. It only drops for a second, but it's quite annoying when jogging through a neighborhood and checking for traffic at every cross street. I noticed it earlier in the run too in spots where I had to twist my shoulders to get around a low limb or something.
I'm wearing the phone on my arm, so there's only about 1.5 ft of linear distance from the phone to the antenna of the headset. Bluetooth should have a range much greater than that. Maybe this was a one time occurance, and I'll give it a second jog to see how it holds the signal then, but if not, I'm planning on returning the headset for another brand.

Rebecca Harris: I have always had problems with losing the rubber ear fittings, or breaking the chords off of the headphone, or breaking the volume control box, or having the big plastic headphones hurting my ears. As a runner, these headphones don't have any of those problems. The first pair I received were not charging and I was able to return them and in a week receive a perfect pair of functioning headphones.I brought these headphones about 2 months ago. In the beginning they worked just fine, although as others have mentioned, they are not the best fit.

Juan Francisco Emiliano (Miami, Fl, US): Prior to the iKross product I had the Motorola S9 or S10 (don't recall which one now) which worked nicely too. I only replaced the set because it was damaged at no fault to the product. I went to iKross based mainly on price and reviews and that the functionality was basically identical. Now that I have had time to compare I like the iKross better. One big problem with the Motorola product is that is the outer rubber surface of the ear buds can come off. Perhaps that is so you can clean them but they kept popping off by even the smallest bumb. Although I happened to find them all the times they came off, the product would have been unusable (completely uncomfortable) without them so the loss of a little small piece would have rendered the entire product useless. The iKross has no such removable rubber ear pieces and I see no reason they are any less cleanable.
