    Just got my cable a while ago and i will say that it did indeed need the burn in time. After the burn in, it is far better than the stock meze liric cable for the low end and overall music clarity. It is a lot less warmer sounding than the original cable, which is something to consider in your music preferences. Overall, I would go as far as to say that you NEED the cable to fully hear what the meze liric is capable of, if you are only using the stock cable.
    Chris was helpful in helping me pick out what i needed, and the process of buying was simple. Free shipping to a far away state and no tax is a total plus.
    My only slight concern are the ends that connect to the headphone; while they are covered with a covering, over time with bending right at the end of the covering it might become a little damaged over a period of a year or later (or it might not, I’m not an expert lol). However, they do have a nice 2 year warranty so there really is no worries when buying.

    tldr; Awesome cables, if you need them, get them 🙂
