The adjustable nubs that are behind the buds make it so that they will not fall out of your ear so easily and they are great for when you hear a song you really want to bob your head to and dance a little they will stay securely in your ears

Not too great not sure about other people but my ears start to ache if i keep the buds in my ears for more than 1 12 hours

Also it has a separate volume from your original connected device if your original device is already at maximum volume or to its most quiet setting the kx9 can make it more loud or quiet with an adjustable volume button on the top of the right ear bud

All its really missing is a skip forwardback feature

Enjoyment 1010they are simply easy to use and deliver really nice sound with no wire tangle hassle i can dance around and they wont fall out they make listening to music via headphones very fun

The sound is crystal clear and surround delivers what generic ear buds cant and for a really good price

Also not recommended for people that want to have music in their ears for more than 2 hours im not sure about other peoples ears but mine hurt after 1 12 hours

My only complaint is that the ear buds theyre removablechangeable have come off a few times on me
