What is the difference between the old X10i and the new X11i?
The X11i is identical to the iconic X10i with a few subtle improvements – The cables on the X11i are square instead of round to be tangle-resistant, and the cables are also re-inforced with Kevlar for added strength and robustness. The tail has been improved by being made of a tougher durometer of elastomer to prevent breakage. The color of the aluminum housing is now dark silver instead of copper. The same great acoustics that the X10i is known for are identical to the X11i, as well as the fit and comfort.
