The Sennheiser CX 300 II has a bigger number.

The Sennheiser CX 300 II earphones are the next model up from the CX 281 at a more expensive price of £44.99. Features stated by Sennheiser include bass driven stereo sound, custom fit ear pieces and high attenuation of ambient noise. It comes with a carrying pouch and should work fine with most MP3 players, iPods, CD players. Looking at the specifications the frequency response shows that yes there will be decent bass (19 Hz) but the high ends won’t be that great at 21000hz in comparison to other earphones like the original CX 175. The human ear cannot hear above 20khz anyway so it’s not such a big deal. The sound pressure level is at 113 Db, a dramatic decrease in comparison to previous versions but that’s not a problem because you don’t need it that high anyhow.

You got mugged so you can’t complain!

Without the public opinion of lots of people it’s impossible to make a legitimate review. Overall customers say the build quality is much stronger than ever before and although the design is different the sound quality is still excellent. There’s quite a lot of people complaining that they broke in to 3 months of usage. It is questionable to whether they bought fakes so be certain that you are buying from a reputable seller, even with retailers like Amazon. Most were pleased with their purchase and found them extremely comfortable to wear. With great sound isolation comes great responsibility, look after these and they will last long. One last thing, because of the apparent comfort fit and high quality noise isolation it will make up for the difference in sound pressure level as mentioned before.

Great comfortable fit, noise isolating and has good bass. Comes with a bonus pouch to put them in.
Expensive, fragile - can break easily so be careful.
