I had another quick listen today at Fujiya Avic to the 334 (and the fitear111 and Edition 8).
They had about 6 IEMs of the Fitear brand there to try, but I only had time for the 111 and 334.
334 certainly do have extended bass, they are very clear and detailed, comfortable in the ears, although a bit chunky in the housing for my tastes.
As I wrote in the 111 thread, If they could make a fitear somewhere between the 111 and 334 I would be sold (perhaps one of the others on display would fit the bill).
