Question about Sennheiser CX 300 Consumer Headphones
This is my second pair of CX300's - and both of them have met the same demise, with the right ear bud losing 80% of it's volume.
Luckily, they are under warranty, but it's still a terrible reflection on the company that 2 out of 2 headsets have had the exact same fault, exactly 12 months post purchase.
Yh im having the same problem good to know its not just me

Had this problem. Left ear bud was only about 20% of full volume after a
year of use. Found that earwax had passed the protective screen and
partially plugged the ear bud barrel.
1. Get a really sharp knife with a thin blade.
2. gently pry off the silver bezel ring on the ear bud.
3. look for a seam in the plastic earbud housing. place the blade edge on it and gently leverage the earbud open. careful not to pull completely apart.
4. remove the barrel end of the earbud
5. place the barrel/screen piece of the earbud in a glass with a tiny drop of dish soap and fill it with boiling water. stir, then inspect the earbud barrel, make sure there is no more wax on the screen or in the bud. Make sure to let it completely dry.
6. carefully reassemble the earbud keeping an eye on the earbud alignment tab to ensure it goes back together properly.
7. Rock and/or Roll

I had the same problem with the right ear bud and I don't know if it is suggested in the manual, but cleaning the mesh on the ear bud with a cotton stick dipped lightly in alcohol (almost dry) helped with me, the sound is back 100%.
I hope it helpes with your too.

Same here for my cx500 G4ME but it is the left side that loses almost 80 percent of the volume.

Offices and stores need active communication at all times for smooth operations. Since, most modern businesses maintain a website or software, they can integrate it with a texting service using a SMS Gateway.

It may happen. If you checked previous suggestions
- checking your own ears (switching earbuds leftright)
- checking if your media player/sound card have sound balanced (same level for left and right ear)
- checking if its not clogged
It may very well be just plain simple failure of hardware.
I had before earbuds in which one side started to sound lower, after i checked all these things it was really just failure of hardware, I fought it by adjusting balance (put it more to side which got lower volume and increase overall volume)
But it kept decreasing until it was so low that having balance completely to that side had no effect. It may be same case.
If you check all above and earbuds are still under warranty, return it to store.
If no maybe start looking for replacement (meanwhile you can adjust it as I did by switching balance toward failing side).

I have been having the same problem for the past week, I have just fixed it, reading your post gave me the idea to clean them and it actually worked
What i did was to "heat them up" with a hair dryer so that any wax from my ear that had gotten inside would "melt", then I cleaned them with alcohol and a q-tip and I made sure I let a bit of alcohol to get inside the ear bud, then I dryed it with the hair dryer again very carefully and tested to see the results and WHALA works just fine
