Verdict: DON’T BUY… if you are going to use it while doing sports. It is as simple as that.
Reasons: Tends to malfunction easily with sweat. I already have two units not functioning anymore. Even though it is advertised as a sport headset, it is not water resistant. No IPXX rating whatsoever.
Maybe if the primary usage is in an environment without moisture, than this headset maybe worthwhile of your money, as the sound quality is not bad for a RM89-RM100 price.
