I bought these because I have very small openings in my ears and have trouble using hands-free headsets. I have s Sony mp3 headset that this resembles and thought that this would be the perfect solution, especially for the money. Now I understand why they're so "reasonably priced" because, even though they fit in my ears nicely, they are only worth about $1 because the sound quality is horrible, they are very cheaply made, the on/off button doesn't work and makes a rattling sound with any vibration, and the earpiece fell apart the second day I had them. I picked them up to head out for work and the piece that fits in the ear fell off. Fortunately, I had some crazy glue handy and was able to glue it back together, but it's a major inconvenience. Fortunately, I ordered a pair of Jabra C220's that have an excellent fit, as well, because of the ear gels that narrow down enough to fit into my ears, and they have GREAT sound quality. I've used many Jabra headsets inthe past and always liked them, so when I found those for less than these cheesy MBat's, I'm thrilled I went ahead and ordered them on the same order. I'll probably give these MBat's to my ex-boyfriend to use with his stereo cell phone. LOL!!!
