First of all, five star for the bargain price.
The pair I have received seems to be a later version than the one shows in the image, but still look very good.
I have a pair of Twins special before I have bought these.
I would say the Twins special ones have a slightly better quality in the manufacturing process.
However, these RDX ones have a much better design than Twins special, I don't mean the visual design, but the functional design, they are just more comfortable and with a much better price, so I would prefer these over the others.
3 words - They are good.
