A few months ago, I bought an earpiece of the brand TDK, discounted @400 baht. The sound is good but I don't know whether it worth THB400. Anyway, last week I went to Pantip and saw an earpiece of the price THB69. Obviously I grabbed it and the result is that it is damn terrible. Seems like the TDK is a good deal for me.

The funniest point is that I was not satisfied with the TDK until I bought that THB69. Human, imperfect...
