I buy this headset primarily for use with a laptop run Windows 7 . I be tire of bulky cord tie I down to a otherwise very mobile computer . the quick version be this : I do not recommend this product . design \/ quality + + + the headset seem sturdy , and come with a nice , and fairly compact semi-rigid carry case . Materials be good . + + + device be inexpensive , definitely a plus . -- the set be very uncomfortable . it pinch the top of the ear tight . I have have other headphone with this design that be much more comfortable . -- the length of the behind-the-head portion of the set can not be adjust . if you be sit down -lrb- for example , use this with a phone in a car -rrb- you 'll find yourself jut you head forward because the back of this headset hit the seat . very uncomfortable . reception \/ technical + + + the bluetooth signal be good , and pick up immediately by my computer . I experience no interruption or interference . -- this headset do not work with window 7 out of the box . the manual have setup instruction for window , but I be confuse that there be step I be not see when I follow along . it turn out that right in the middle of the instruction , in small print , you be direct to the manufacturer 's website to purchase additional accessory -lrb- dongle -rrb- which be require to pair this device with a laptop , even if you computer have build in bluetooth . -- 3rd party bluetooth software will recognize this device as a generic headset and will pair with it , but most cost money -lrb- most be more than the headset itself -rrb- . + + + when listen to music -lrb- phone , computer , etc -rrb- the sound quality be stereo and excellent . quite impressed for such a small , inexpensive device . + + + people comment that the mic sound loud and clear . -- when use this as a full headset -lrb- talk to other people with it -rrb- the sound become mono and the quality drop very noticeably . I be not a audiophile , but this sound be jarringly bad , . it be enough to distract I from what I be hear . I try numerous workaround but could not get high quality sound while use the mic . in conclusion , I be return this headset because it will not work for my laptop , the main reason I purchase it . that the instruction walk you halfway through setup before tell you to buy additional accessory and\/or software be very annoying , almost deceptive . even for a phone or other bluetooth device I would not recommend this product . the headphone be very uncomfortable , much tighter on the ear than similar design that I have own . the headband stick out from the back of you head significantly , and the whole setup can get knock off you ear easily , despite how tight it clamp .
