This was my first experience with wireless ear buds. I was one the hunt for a product to use in the gym that did two things:1) was wireless2) didn't actually go inside my ear. My ear buds were giving me ear infections!After using this product for a few months, I'm overall pleased with them. They have good volume, you can hear above the noise of the treadmill. They stay on and securely in place, even while running. Once you memorize the buttons, its easy to adjust without taking them off. They are comfortable.There are a few cons. They don't hold a charge for very long, only two to three hours, so I have to charge them every other time I go to the gym. Its a slight pain and because of this, I often forget them. They also SEEM cheap, but so far mine have held up. They look a little silly on, if you are worried about that kind of thing. For me, so far so good.

Merits:1. Super light. You won't feel it when you put it up. It's very comfortable when you wear it and running or do whatever you want for a long time. This is the most important thing when you buy earphones for everyday use or training etc.2. Sound is not bad. For me the sound quality is enough. It's worth less than $30 after all.3. Easy to use. I didn't run into any problem connecting with my Android phone and tablets.4. I like the design. The receivers are besides the ear, which are clearly better than some design which put receiver back around your neck. When running, those receivers will work as a hammer and smashes your head and back on and on. And the size of this receiver is not too large. I think its cool that I look when I'm wearing them.Shortcomings1. Winds blowing may cause a lot of noise around your ear.2. I think it is not waterproof as it is not described as so. However if it is waterproof, I will pay $40 for it.

Product is lightwight, has great sound, and easy to connect to devices. However, the ear bud is very uncomfortable in the ear. I can only wear for short periods of time (less than 30 minutes). I purchased this mainly to use with my kindle, as I like to listen to the books while I work. The charge will last all day, but the my ears won't. As they are hard plastic, there is no give in the ear canal.As this is my first purchase of blue tooth headphones, I'm happy that I did not spend a lot. If comfort is what you are looking for, these are not the earbuds for you.

Connects easily, good sound, right ear not as comfortable as the left, good battery life. Great light weight Bluetooth headphone for running. Buttons are small, but useable while running. Haven't run in a downpour or when sweating heavily, that will be the final test.Update, ran in warm weather and the sweat made it so the buttons didn't work correctly. Right earpiece is now quite uncomfortable and falls away from my ear canal. I got two good months out of it for $10.99 plus tax. Not the best, but I'm glad I didn't spend more.

Everything is exactly as describe. The earbud is extremely light. Fits comfortably and I can hardly feel that I am wearing it while running.This bluetooth earbud can connect my Galaxy S5 fast and easily. I am impressed by the high rich sound, no any echo. Now I feel more enjoyable whie doing sports. :）If you like doing sports, this small earbud is the nice choice for you.

I'm generally happy with the transaction but within a week or so mine developed weird black spots symmetrically on both sides inside the plastic tube. Darker on the right side. I like the design, very light weight, sound is very good and loud. These are my first BT earphones and i'm not picky about sound quality. I won't go back to wire again that's for sure. Good for running, walking, exercising, good fit for my ears. Tested with pandora app android phone, set to slightly below medium volume level, within a few feet of the phone battery lasted a little over 6 hours of continuous play. I'm not sure if good/bad/average. Can't compare to anything else. Takes 2 hours to charge. I don't read instructions, had the control buttons figured out after a few uses. Power, volume, pairing, rew/ff easy to learn and control. No problems pairing with any of my android devices or pc. I have yet to try using them in hot humid weather.

Sound pretty good but totally useless to me. I cable is too short, therefore doesn't sit in my ears properly. I would not recommend unless your head isn't any bigger than an infant......I emailed KMASHI in China but no reply. I imagine making the cord longer is too much to ask.

Very good long lasting battery and durable because I had this in my pocket for two years and now I need another one
