Sennheiser CX 300 II-Black

Bloated and muddy bass with a veiled midrange and a lackluster treble. 

These are horribly overpriced in Australia and can be found at an authorized dealer from $60-$100, although I bought mine way back in the middle of 2009. What can I say, there are so many things out there for the price that whoop these thing sonically that there is absolutely no reason to own this. The amount of counterfeits floating around astronomical. I must say they are quite durable though.

These were my first step into the world of audiophillia.

Best Part Of these Headphones are the Bass.....  And Worst Part Of them is Bass.... Yess...... Audio lack quality... In fact no detail at all.. mids and highs are not present.... various instrument goes unheard... 

Don't go for these earphones if audio quality is your concern.... These are just suited for thumpy music found in electronic and hip hop.... that to below expectation....

I bought these looking for a replacement to an older pair of in-ear's, and happened to stumble upon these.

At first, I was very pleased with the sound, as it was a drastic difference compared to my older pair. Only now i realized that these are IEM's after visiting this sight. It was only after i bought my AKG 240's I truly noticed the sound quality.

The sound quality you ask? Well they are very nice overall, as expected from Sennheiser. The only big flaw is the amount of bass seems to drown out all other sounds. The high's seem to disappear every time the bass kick's in which is obviously a great draw back.

Otherwise these are very comfortable and fit nicely into your ear and stay there like they should. The isolation is superb, and coming from a person who takes a clankity bus every day to school, that means something. No leakage either.

I would recommend this to Bass-heads, or people who mainly listen to Rap, Hip hop, or love bass solos.

I purchased these from Best Buy, having read good things about Sennheiser during my search for a cheap pair of IEMs for the gym. I ended up exchanging them for the CX400-IIs because I was disappointed with the 300s. They did not perform like a base model should.

I was displeased with the lack of clarity and separation. And I realize the for under $100, I cannot expect too much, especially from a single driver. However, these were not much more pleasing than my Sony IEMs that I got from Target for $30.00. Spring for the extra $20 and get the CX400-IIs. The difference in clarity and separation is immense between the two similar models. Also, the soundstage on the 400s is broader, and the sound is more dynamic. The 300s sound flat.

On the plus side, the size of the 300s and 400s are the same, and they fit wonderfully in my ears. They are very discreet and comfortable. Not clunky or awkward at all.
