The E18 gives you a more balanced vocal range, and a more controlled bass along with a clearer sound signature that has qualities similar to an O2, but it has problems in the upper mid range, and high range with sonic fluctuations and deficiencies that may make it more analytical for some headphones.
The two units are quite different in their functions, although the E18 can also be a computer and portable DAC/amp. I would go for the E18 if you want a higher quality sound (at a loss of cohesion) and want to make use of its Android features. I would go for the ANDES if you want a funner sound, don't have as much money for the E18, take a gamble at trying to get it to work with Android devices (it is known to work with some), and want a device of that size.
