i think this is the Best for Quality and Price
1) battery life very long- you can listen at list a week about 3-4 hours a day or more
no worries about charging -before i charge it every day !!! so i continue charging with KORSKR too
but quick understand that its not necessary at all;-)very easy have control about how many % you have because you can see bright big green numbers in the box
2) a very good balance between base middle and hi tone pretty good noice isolation
3) my ear feels good because have good position and clips is very secure -its very important for me when i jumping or run..
over all nice earbuds and trouble free ! recommend for everybody good price and good sound

The sound is good and the bass are surprisingly good too. Confortable and stay in place whatever acivity you are doing. The controls are pretty sensitive and easy to use.
Easy to pair and pretty fast to charge. I love the case, it is compact and you can see the level of charge.
The battery life seems to be good for a small item like these.
Overall, I'm very satisfied with this product; specially for listening my music.
Thank you Korskr for the quality and the value for the money of your earbuds !!!
Haven't had any issues with sound, and mic was good enough to work while taking public transit, though I had to hold it near my mouth.
It's pretty comfortable to wear, and if I want very low volume I can hang it on my ears without stuffing the earbuds in. I'm also yet to drop it, compared to my other earbuds which I've dropped countless of times since they're small and I don't want to press buttons.
Volume when connecting/pairing and receiving incoming calls is pretty loud, which is a bummer, but that's the only thing I don't like about this. Battery life is fantastic. Would recommend.
It also makes sense that I have never once regretted my choice, to give my eldest the super expensive, quite new Galaxy Buds 2 after spending a few days with the KORSKR i21's. While the Galaxy Buds 2 are what I consider really expensive, I got them for free. I purchased the KORSKR Earbuds because the Galaxy Buds 2 kept almost, or completely falling out of my ears during VR games. However, after spending a few days with the KORSKR Earbuds and trying them in various situations, such as playing VR, listening to music, phone calls, and PC gaming, I realized that I liked the sound from the KORSKR i21's much more than the Galaxy Buds 2. To me, the i21's sounded clearer when listening to spoken words, while spying on conversations between multiple NPC'S or players on an opposing team, I was able to follow along and know exactly what was said, I could hear the subtle differences in tone that let me know exactly who was speaking, even when I couldn't see them. With music, the i21's from KORSKR seem more responsive to subtle changes using an equalizer yet, it is not necessary to use anything extra to clearly hear the lyrics on a head banging metal piece, to follow the rhythm of each drum at an Aboriginal event, or to relax into the hummm of a recorded singing bowl as I attempted to meditate.
So, when the packers went overboard and packed my original pair of Pink KORSKR i21 Wireless Sport Earbuds, (as well as both my dogs' collars and leashes lol), and I realized that finding a new place to rent was going to be harder than I thought, so my things that were packed into a 10'x10'x10' storage unit were going to be there for a few, perhaps several months, I knew what I had to do. I certainly didn't browse the Samsung website (although I love their phones) in fact, I didn't even browse Amazon! I knew exactly what I needed, so that what I was listening to was awesome and private. I went straight to my purchased items, found my purchase of Pink KORSKR i21 Wireless Sport Earbuds, opened the page and decided on Black KORSKR i21 Wireless Sport Earbuds this time, put them in my cart with some vitamins, changed my address on file to the address of this really amazing homeless shelter I was lucky enough to get into, (many thanks to V who works at Surrey Memorial =)), and a few days later they arrived!
They sound as amazing as the first ones. Why pay hundreds of dollars to advertise for someone else? KORSKR has proven they know exactly what consumers need for any activity they choose, and they have packed their knowledge into these amazing KORSKR i21 Wireless Sport Earbuds, for a fraction of the cost? Oh, they're really comfortable too, I always pause the sound for something and then forget that I have them in!
Now, in order to have the entire set, I just need the Red KORSKR i21 Wireless Sport Earbuds.
P.S. I chose a gift just for registering my product, before I ticked five stars and gave this honest review.
