DannyB,
the Elevens are big and i wouldn't wear them if i was having a serious day on the mountain.
the quality in sound is better with the stealths, the size of the driver is the same 10mm, but the stealth has a wider frequency range 16-20 (human hearing range), alpha is 18-20, so not as wide. the stealth handles and enhances the bass better than the alpha. but in the end it comes down to what music you listen to and how loud you listen to it.
the cords are made of tangle free woven cables and are solid.
both buds come with a range of cap sizes so you can swap them to find the best fit. Alpha has 4 sizes, stealth has 5.
there is also a new model out the Codec, which is an entry level set, the sound is good but not the same as the others and it has a tangle resistant rubber cord.
prices in OZ: ALPHA without mic: $49.95, with mic: $64.95. Stealth without mic: $79.95, with mic: $89.95, the Codecs are $34.95.
