Gear Days - Summer Super IEM Showdown

Since I've been at the headphone collecting game for about a year now I thought I'd start doing yearly headphone roundups broken down by headphone type.  For summers I think IEMs or in ear headphones are worth a look at.  For falls I think that on ear headphones are a good topic.  And for winter I think that over ear headphones are the most fitting.  In spring I'll do the full gambit with a full relisten and a completely updated ranking.  Why such arbitrary month matchups?  Personally I think summer is the season most about traveling and a good pair of in ear headphones can take you a long way if you don't want to get noise cancelling headphones.  In the fall, I like walking around outside as the temperature begins to drop but isn't too cold yet.  On ears tend to be cooler to wear outside than over ears so they get fall.  Winter is the coldest month and over ear headphones can work as pretty good earmuffs so that's that.  Spring is the time for rebirth and a fresh outlook and so a full listen will be good to reassess the top and the bottom alike.  Now for IEMs.

Currently I have 9 pairs of in ear headphones.  Ranked from 1 to 9 they are:
1. Brainwavz B2
2. Klipsch X10
3. Shure SE-315
4. Sennheiser CX200
5. Sol Republic Amps
6. Klipsch S4i Rugged
7. Nuforce NE770X
8. HiSoundAudio HW2 Wooduo 2
9. Zipbuds Juiced
