can anyone give me advice I bought these to use for laptop. I synced it with my bluetooth settings on my laptop and it picked it up and downloaded the drivers. But when i go under devices click the headset and try clicking the option "control" it gives me an error message reading "An error has occured when intializing this operation.Try restarting your computer or bluetooth device."I tryed doing that and im still getting the message. i tryed removing it and resyncing and that didnt fix it either.The headphones pick up recording audio but the do not playback audio such as music or movies playing on my laptop. Can any one help me?? April 14, 2010
Good, but not great. For bluetooth the sound is great. i can hardly feel them on my ears anymore. however to do this i had to wrap gauze around the frame above my ear because it was fairly sharp there. Mine were refurbished but nothing is wrong with them as far as i can tell. Performance wise however, they lag alittle behind video while watching on my laptop. But they work fine for phone use and music playing. the skip and rewind button does not work for my iphone however. January 17, 2010
Excellent Wireless Choice Excellent wireless earphones. Sound range isn't as deep as corded, but not having any wires to deal with is great. Product works exactly as described. June 15, 2009
Nice wireless headphones for your iPod If you're looking for good quality wireless headphones, look no further. This product does exactly what it says it does. The sound quality is excellent for wireless headphones and yes, it will work from 30ft. This feature doesn't actually excite me because I don't normally lay my iPod down and walk 30ft. away from it; but at least you know you can if you so desire. Don't expect the kind of bass that you'd get from Sony's high-end corded earphones, but that's the trade-off for dispensing with the wires. The transmitter plugs into the bottom of, and is powered by, the iPod. You do, however, need to charge the actual headphones with the supplied AC adapter. This isn't a problem because the battery in the headphones lasts a long time. I haven't tried draining the battery completely in order to test exactly how long it lasts, but I can say this--you'll drain the battery in your iPod long before you will the headphones. So whenever you charge your iPod, just remember to also charge your headphones and you won't ever have to worry about the battery life on the headphones. The physical design of the headphones is clever. They wrap around the back of the head and over the ears. This not only provides comfort and stability, but it looks pretty cool as well. The engineering design suffers from one flaw, however--the headphones disable the volume control on your iPod. That means that you'll have to control the volume from the headphones. The volume buttons on the headphones are a bit small, but once you get used to their location on the right ear piece, you shouldn't have a problem adjusting the volume. I'd still prefer using the iPod's volume control, but this is a small inconvenience for everything else that the product delivers. Overall, I'd rate this product a 4.5 out of 5. April 24, 2009
