I am currently using Sennheiser CX-300 Black and I am a Senheiser lover.
As compare to CX-300, the CX-300 II Precision delivers a better bass and mid-low frequency, suitable for R&B, Techno and those upbeat musics. However, its lack of treble making the sound muddy and slightly muffled.
The earbud and cable are no difference then CX-300, which the earbud is confortable and good noise-isolating but the cable is making interference noise as it run against your shirt or when you swing it slightly harder. The hang-neck cable is more to personal favour, so I won't judge that.
As for the pricing, Sennheiser's product had its quality within the price for the CX-Streets earpieces. Still, the quality achieved within the price is better than most good brands out there. Shure and AKG pricing is way more expensive as compare to Sennheiser if they have the same sound quality. Therefore, this is worth to buy.
To conclude, the CX-300 II Precision is more suitable for people who love bass. However, if you like more clarity and acoustic sound, get a CX-400 or higher end models if you got the budget, and for those who had low budget, a CX-300 is ok :)
*P.S. no matter what, it's all about personal preferences and needs.
