Gotta choose, please help!
I really enjoyed my PL-30 for the nice soundstage for a cheap IEM and the more clear sound (not too bassy). The thing is it really depends on what type of music you listen to, what kind you want out of a IEM like better bass, clarity or detail. That helps people suggest headphones to you. Also take a look at |joker|'s http://www.head-fi.org/t/478568/multi-iem-review-268-iems-compared-visang-vs-k1-added-01-03-13 or ClieOS's http://www.head-fi.org/t/541204/concise-multi-iem-comparison-rock-it-sounds-r10-r11-r20-r30-r50-added-dec-31st-2012. These two are a must read when your looking for headphones or IEMs. Hope this helps
My vote goes for the CW31, I've owned the beta and hated it, Sounded bad and the build was BAD, it broke within 2 months.
The CW isn't the perfect set but it sounds really good. A big plus is the build and of course the Customer service from the MEE guys is second to none!!
