In fact this is my 2nd set of the headphones as the first one had the same problem, after a period of use (even though I do clean it, most of the times..) the buttons fail to work.

You see the buttons that connect to the ear speakers, are cleverly designed to allow you to forward/rewind tracks, pause/play, increase/decrease volume and even answer or hang up calls without going to your ipod/zen/mobile or any bluetooth music device.

These buttons are just a quick touch so you never have to take out your music device, in my case I use my Nokia e51 to play back music. This is very useful when you’re running and you don’t have to fumble with cables OR the music device.

However, after about 6-8 months… the bottom row of buttons stop responding totally. Usually you will hear a click sound, to know the function is activated, but no more. So I lost the control to Backtrack, and decreasing the volume. I get around this by having a playlist and doing the volume control on my e51.

Today I did my 10km run and, for some unknown reason (could be the pairing) the music just keeps going off after a while. While the headset is fully charged, so I had to turn off and on the headset so that the music will play for again…. for a while

And even worse, could be a button fault.. sometimes there’s a constant beeping that interrupts the music…Sigh.

I thought of getting a replacement the new Motorola S9-HD, which is the supposedly improved version of the first generation S9.. but from what I read from the online reviews, even though the music quality has improved a lot… the sweat problem has not been solved.

Hey Moto, if you happen to read this, the S9 is a great product with real good design and much thought put into it… But please solve the sweat problem!

Guess, I’ll be looking for another pair of ear phones to run with soon. Need to train for my 21km…
