My friend have just got his T51 and I have few minutes with it. It is a black one looks roughness from the side to back. The face of it looks very simple, have no extra design except a power switch (too small to press), even no logo printed on the face. It is really bulky and heavy. About 100Gram. The back cover is made up of paint coating aluminum.
The stock earbud is very inferior. it is no a problem for audiophiles, for they have lot of rest other phones.
The sound quality is very personal subjective. So above review is worth to respect. To my ear. I don't want to give too much conclusion, for I am not an audiophile. all in a word, with the designning of 5 "cores" and with two wolfson DACs, i expect the sound could be much better.
There are still have no veteran core audiophiles full reviews. I also want to read it as soon as possible. I hope my first impression was wrong.(too brief to listening to it). For I really can't resist the temptation of the low price and can get a line out function.
get some good source and earphones or headphones to test it out !
if possible, try its line out also. thanks ! haha
