Summary: I bought these for my wife, who wanted them because her other ear buds kept falling out of her ears. She tried them once, and had nothing but complaints. She said they wouldn't stay in her ears, and they sounded terrible. A few days later I tried them myself. I thought I could get decent sound by adjusting the equalizer on the music player. I put them in my ears, and heard nothing but high pitched treble.
Summary: I realize that these headphones are on the cheaper end of the market, but mine ended up breaking after only a few weeks of owning them. Initially they worked great and I was satisfied, but after a few uses one of the buds stopped working altogether for no apparent reason. With only one working speaker this product became useless to me.
Summary: Truly awful in the fit department. I would consider my ears to be quite normal in shape and size. The time I spent experimenting with all of the ear tips and trying unsuccessfully to get the "memory wires" to conform = 40+ minutes of my I'll never get back. I'd describe the sound quality as "unremarkable" at best. I had high hopes, but these were not for me, I found them awkward and ill-fitting. Glad other reviewers have had good experiences.
Summary: This is a terrible product. I've been running with headphones for years and have used many differnt styles and brands, from headbands to ear buds and Sony to JVC. While sound quality varied, they all held up admirably in a diverse range of conditions, including high altitude, intense heat, humidity, rain, mud, and even ash. All except for these headphone.
Summary: I am a runner - and I sweat a lot - I purchased these in the hopes that I could finish my run WITHOUT them falling out of my ears... WRONG! these are horrific... they do come with lots of little ear bud covers so you can get the right fit - doesn't matter - I tried all of them - they all fell out... I think the problem may be with the way it hooks around the ear - or just that when they get wet with sweat they are just too slippery.
