I was in Singapore and wanted to drop by Null Audio's showroom. Called their number for like 3 times during their working hours but nobody picked up. Searched local Singapore forums & people commented about fishy business going on with Null Audio. Sent them an email and no reply. No way I'm going to put my credit card to place an order with a company like that.
Next best option and cheaper as well, was the FiiO RC-UE2.
Packaging is simple, tear to open the pack. Good, I like it, the money should be spent on the product, not the packaging.
Build quality & appearance:
Tight braid of silver plated copper. Appears silvery/white, and appears to be solid core wire as per their description on their website. Connectors are well machined and no rough edges in grey. Also, the connector to the left & right ear piece sits flush, no gap, so that's good.
Its slightly worst than the stock cable but no where as bad as some reviews say. If you have music playing it won't be an issue. I use this commuting on the train and have no issues walking. For running I wouldn't know since i rather drive than run.
Better than stock, significantly improves the TF10 in terms of better clarity, opens up the vocals. bass wise I don't notice a change, it was pretty good to begin with. FWIW my original cable is the one with a mic+button.
The loop on the ear is sorta "fixed". Its soft, but won't curve any more or any less, its just that shape. No memory wire in it. The wires don't easily tangle like the stock one.
Should come with a nylon sleeve at the very least, would help with the microphonics, I don't like the feel of the braid but that's personal. And the color is very boring, I guess with a nylon sleeve you can have it in any color you want. White/Silvery is so iApple.
All in all, for the $34 I paid, its great. Don't mind paying a couple of bucks more for it to have a nylon sleeve.
