Most helpful positive review

the one thing I hate about my Sennheiser CX-300's is that the tips constantly fall off and are lost in my pocket, bag, suitcase, etc.
These replacements are great...they fit perfectly and are nearly identical (if not the exact same tips) that come with the CX-300's, and I prefer the large size because I feel they best isolate noise.
Another bonus is that they are also compatible with the MEE MEElectronics M9P earbuds (I own a pair of those because of the inline microphone), and so buying these tips has given me replacement tips for two earbuds from different manufacturers.
A great find.
