From the acoustics, there is no audible difference.
The advantages of this cable are much more stable and better processed RCA plug, which also better to sit on the connection.
The ratchet head is thinner than that of the in-acoustics and therefore more suitable for use with smart cover.
The significantly lower price.
The only advantage of the in-akustik is the textile sheath of the cable for durability.
Strong buy recommendation !!!
