good size.
you can use any headset.
stock headset is good.

Good price.
barely uses any power when you leave it on, on accident.
sound quality seems good.

Cons: buttons are easy to press.
some of the buttons are trick to press.
doesn't give enough warning for when its gonna die. maybe 2 mins at most.lasts about 6-8 hours of continuous use.
poor call quality.

Other Thoughts: I work at a computer and do stuff around the house and these work really well in both situations. i haven't really had any issues with the device. i do sometimes press buttons on accident, but its not that often. the range on it is about 20-30 feet so its not too bad. i can keep my phone out of harms way. the stock headphones are great and i haven't needed to replace then. all in all if your not expecting super high quality and you just like listening to music or movies you good with these. charges within an hour or so so its nice.

Pros: Easy connect.
comfortable ear bud adjustments.
long battery life.
very light.
nice design.
well placed mic.
Charges fast.
looks good.
sounds good.
Good Distance

Cons: buttons are really really low profile.
super slight audio lag.

Other Thoughts: All in all awsome, i watch movies and shows and stuff with this thing while im at work. its really nice to not have the wire anymore. i make calls, play games, listen to music, you name it. the fact that you can change the headset is amazing. i plug my big headphones in when mow the lawn or do house work, and use the stock ones when i go for a run or am just moving around. the sound quality is really good and you can control the volume really well by turning it down in small increments to get to the right sound lvl. with normal use, i usually charge it every other day. the few things i dont like is the volume buttons aren't labeld. no +/- so i had to figure it out. its pretty obvious though, when up right, the top button is + the bottom button is -. also, if your watching sometihng and your really really focusing on there lips, you can see a super small audio lag. this doesn't happen on netflix because netflix adjusts the video to match. so all in all amazing product for 40 bucks.
