My CX150's feels like they are dying (have to move the cable around for it to get sound through) so I started looking around for the Senneheiser CX series, since they sound quite good (after switching the tips).
I noticed there are alot of reviews for the CX300 but not as much for its revision the CX300II Precision.
I'm trying to decide between the CX300II Precision and the CX270/280 (in brackets because the two are the same except for having a volume slider).
Just by looking at the numbers probably the 300-II is probably better?
Or will the 270/280 beat it?
They're both probably in the low-mid range of IEMs,
The CX300II are pretty popular I can see alot of people having them.
I've seen the 280/270s a few times, it looks like the housings for those are bigger and are vented at the big. Perhaps different drivers and a bigger sound space (because it's vented?)
Any recommendations between these 2 or impressions about these 2 are greatly appreciated.
