The wired version, was a test version and was released only in asia, mainly Hong Kong and China from October 2016, it was a follow on foot step of the AK T8IE Mark 2, apart from the color, AK logo and being tuned up from the AK version, it's really no different from the T8ie MK2, even the supplied accessories are the same, see post 24 for photo's.
The differences between the wired and remote is just a new face plate, remote version being plastic (I think) and the wired version being metal with a sandy texture, remote version also gets a audio only cable along with a remote cable, a new leather case, extra 2 pair buds, extra pair of filter and a bigger box.
Although the wired version is older, it was sold at the same price of the remote version USD 999 original price, but I was able to get it for about USD 750, this was back in January.
That being said, the Wired version has now being discontiued now, and only remaining stock are those left in the stores with prices range from USD 750 and upto USD 1050, and the sole agent in Hong Kong and China has no intention of stocking the remote version, but are waiting for the new wireless version when they are released.
All version of the Xelento are the same apart from the differences in the face plate.
