Pros none. The product is rubbish, and the company wont back it up.
Cons Save your money, put up with a wire until they come up with a better option.
Summary Dont bother.
Pros Fantastic functionality! Pauses/restarts bluetooth ipod with one touch with no additional equipment. Cell phone calls clearer on this device than on many high end single ear bluetooth headsets I've used. LONG battery life! 7-8 hours at least.
Cons A little buggy. It locked me out once and I had to let it's battery completely die (7 days) before I could reboot it. Biggest con is the fit. Slightly adustable, but not made for small or women's ears. Earbuds NOT fitted. Easily dislodged.
Summary I got these earphones as a gift and immediately discovered the fit was less than ideal. The shanks that attach the over the ear part to the earbuds do adjust but even contracted down to the smallest size they go, they were still too low in my ear and did not fit down into the ear canal where it seems like they should. The earbuds are small, but because of the contour of the device, they always feel like they are sitting just outside of my ear, just about to fall off. They DO fall off pretty regularly, especially when you are sweating or moving around. Wire that connects the two earpieces catches on your clothing sometimes, but it would be way worse if there were more bulk and weight along that wire, as in some other earphone designs.
Other than that, the device works very well. After an initial freakout, the headset has been working perfectly for about 4 months. Pairs easily with both my iPod Touch and my HTC cell phone. Calls are clear and those I call report they can easily understand me. Battery life is amazing. Easily 7 to 8 hours of continuous play - longer if you have things paused or are only using it for cell phone. Bluetooth reception is great too. Worked flawlessly with the cell phone, and after Apple got their act together and fixed their bluetooth transmitter, worked very well with the iPod too.
I love this headset, but I'd love it a whole lot more if I could keep it on my head. A great headset for driving, and I love the wireless, but I need something that will stay in when I work out and this just isn't it.
Pros Good audio quality
Bluetooth dongle gives me access to cordless audio from almost any source!
Long battery life
Cons Odd habit of getting "lost" and requiring hard re-set
Audio quality could be better
mic could be MUCH better
Summary I've had these for over a year and wear them almost every day. Maybe my expectations a to low but I love them! I use the bluetooth dongle with my PC at work, my Palm TX, my PC at home, and any place else I need to listen to audio. Don't get me wrong, they are not perfect. The sound quality, while good, could be better. If I could change one thing it would be to improve the microphone and it's ability to deal with wind and background noise. I use them mostly to listen to music and podcasts at work to drown out the folks around me. At home I use it to listen to the TV without disturbing anyone with the sound levels. If I had to go out today and buy a set of headphones I would buy them again.
Pros Decent sound quality, bluetooth fob for non bluetooth audio devices, dual charging head so you can charge headset and fob at the same time, decent battery life
Cons Terrible fit, sometimes tinny and static sound
Summary After reading several glowing reviews of these, I purchased them and I am quite disappointed. The worst part of these is the fit. It takes forever to get them on in a comfortable position and you constantly have to re-adjust them if you are moving at all, as they will slip and slide out of place. Once you do get them on, the sound quality is decent, but can be tinny with static every once in a while. The best part of them is the bluetooth fob for non bluetooth devices and the dual head charger so you can charge the fob and the headset at the same time. The fact that the charger is the best part of this package should tell you something. I would not buy these again.
Pros Great product if you stay away from moisture avtivities
Cons not moisture resistant, although it does say so on the disclamer
Summary Good product if you do not sweat
