Last year in March I bought a Fiio X3 2nd gen for 159 GBP. By the end of the summer I stopped using it and it has been collecting dust ever since. I also bought the matching leather cover and a 32 GB memory card.
I would like to sell the Fiio + memory card + leather cover for (see post below!), which is roughly 60% of the original price. I think it is a reasonable price given that I have used it very little. I am not sure I kept the original box, but I will try to look for it.
