Not sure what you mean by that (highlighted text) here, but the 1p2 massive price hike (nearly double what it originally retailed for) happened quite a while ago, while the TG334 still retailed for $1,350. The TG334 has always retailed for ~100,000 Yen in Japan (ie no price change).
To clarify a few things regarding pricing:-
The original 1plus2 were offered at an introductory price of $980 with silver cable and $1080 with silver/gold cable for few months.
However, after the initial launch exactly a year ago, they were redesigned completely, especially internally, in November 2012. To the point that there is no semblance to the original 1plus2, in appearance and sonics. The price change reflects the redesign and are priced at $1250 and $1450. However, the original were to be priced at $1180 and $1280 after the introductory offer ceased.
Every owner of the original 1plus2 were offered the opportunity for a replacement to the redesigned 1plus2 free of charge, in which every customer took up. nk77 being the last customer to do so.
We are the only company that makes and tune our cables specifically for our earpieces, from foundry to retail product.
Hopefully this clarifies our pricing policy for the 1plus2.
