Review on Premium Bluetooth 4.2 Earbuds: Sport Stereo Headset with Mic - High-Fidelity Sound for Sports, Running, Gym by Cathy Sharp

The instructions are almost clear. But they do little to explain the meaning of the LEDs. Finally got it charged and tried it today. I connected to the iPhone with no problems, but I found that the sound from the left earbud is much better than the right. It's like the right earbud is just for treble/treble while the left earbud is for the full range of sounds. It confuses me a bit when I use both at the same time, for example the left one is too loud and the right one isn't loud enough. They will work for a cheap pair that I can use at work and mowing just hoping for better quality.
