I don't think one actually gets bored with the actual purchase. The results of the said purchase might do though, for me, it gets thrown into my "never speak about or listen to anymore" box.
But going back to FitEar, every pair of their customs, I use frequently, when I am out. If one were to critique them, they may not be the best in any specific element, but they all do sound awfully correct to my ears in presentation as a whole. Certain pairs have their stylized sound to cater for specific genres. But with the 435, MH334 and the 223 you cannot go wrong.
I should add that the 223 is the absolute bargain of the range, priced around the Parterre and under the TG334.........great entry into the customs from FitEar!
