Mini Wireless Headphones by Calerix, Bluetooth Headset Smallest, Noise Cancelling Sports & Running In Ear Earbuds with Mic, Cordless & Portable, Fashion Stereo Headset for iPad, iPhone, Android Mobile

Really big and uncomfortable. Pushing the button is frustrating and sometimes difficult. The case and charging situation are pretty cool though.

The connection is not good, when I'm on a call people have a very hard time hearing me. So This means I won't be getting that much use out of this product... Not Good at all.

I haven't put it to the test as to function...but I like that it came to me in tack.

Doesn't fit well in ear, have a hard time following instructions as they are unclear.

This item works great! I have yet to have these not pair with each other for stereo sound. Just for info on stereo pairing, make sure the bluetooth on your phone is off. 1st make one ear peace go into paring mode. The second it says "pairing mode" turn on the second ear piece it says "on" wait a few seconds and the second ear piece will blink very slowly and the 1st earpice will still flash red and blue. Now turn on your bluetooth and pair...These steps worked every time. I have turned them on more than 20 times.Comfortis ok. Make sure to change the ear bud for your ear size.Getting it in your ear and making it stay there requires a few times to get the right position but once you know what position is best the earbuds stay in.The only con that i have is the design. People tell me it looks like a lipstick. They could have come up with a unisex design. For women this is perfect but for me I find myself not leaving the casing out in plain view. I take the earbuds out and the case goes back in my pocket or backpack.The sound that these put out is great especially in stereo.PROS:Stereo soundBuilt qualityFair priceGreat soundCONS:design for me (looks like lipstick)

There is a lot to be desired of these headphones. They are light and portable. The range is on par with most bluetooth headsets. Pairing is easy and the charging base is very nice and portable. The calling and receiving work well and is relatively clear. The only issues I have with this unit are the comfort of the headsets and the battery life. I have used these for 3 days now and I have not been able to get more than 3 hours of use per charge. And for the life of me I can't seem to get these into a place in my ear that I am not aware that they are there. They are not necessarily uncomfortable but I don't like the fact that I am constantly moving them trying to find a more comfortable place for them. The base isn't very good, either, but that might just be an issue with how I am wearing them. Nice and portable, not perfect, but not too bad!

I was looking for wireless headset for quit some time, but could never find suitable product for me.I was very pleasantly surprised with great quality of those headphones for such a low price.They are easy to pair and ear wings are very convenient to help keeping earbuds in my ears secured.Absolutely love the product.Unit itself very stylish and comes in nice box. I will make great present for anyone.

Lets see, I'm going bullet points...1) Battery life is terrible2) I got no ear hooks nor neck strap3) Range is well... not existant- One earbud cannot talk to the other across my head, though if wife and I each take one ear bud ~3ft apart it worksGold Star: One ear bud is in english and one is in chinese2nd Gold Star: After 2 mo, they both became a "master" and I can't get them to repair.. so I have TWO K3 earbuds as separate Bluetooth targets.
