4.0 out of 5 stars Not so good for walking/jogging, May 4, 2006

I bought the CX 300S earbuds to use with my portable MP3 player while walking/jogging. The rubberized cord tends to stick/cling to your clothing which results in the buds getting yanked out of your ears as your clothing moves around (not to mention the fact that the cord is a little too short.) The buds must be fully inserted into your ear canal in order to hear the full fidelity of the music. With the buds fully inserted, most of the outside sounds are silenced... but this has the effect of amplifying inside (in-body) sounds such as breathing, teeth chattering, swallowing, etc... as well as the sound that the cord makes as it rubs around. Also, as the air moves past your head (while walking) you'll notice very pronounced wind noise! I also noticed that once you get the buds properly fitted, then you smile at someone, the buds tend to pop out! No more smiling!

Now, let me say that if I'm sitting at my desk with the buds properly fitted, the sound is amazing. Very good fidelity with bright highs and nice bass. But, to fully enjoy your music, you'll need to sit perfectly still and breathe gently (and don't touch the cord!)

If you're skeptical about the amplified internal body sounds, try this experiment: take your index fingers and gently press them into your ear canals... not all the way in as to fully plug your ears, but gently about 2/3's of the way in. This is about where the buds will sit when inserted. Now, gently tap your teeth, or take a deep breath. Take your thumbs and rub your index fingers... you get the idea.

I know that this is not a defect with the Sennheisers... this is an inherit problem with anything that you'd stick into your ear canal. And I've now learned that I absolutely hate in-canal phones... very, uncomfortable and inconvenient (and I've recently learned that in-ear phones can cause hearing loss.)

I am switching back to my Koss KSC75 Portable Stereophone Headphones which sound amazing. And they're so comfortable that you might forget that you're wearing them.

Bottom line: If you're a fan of in-ear buds, then I recommend the CX 300S's... they do sound very good when properly worn. Since most of my gripes are with in-ear buds in general, I cannot fault Sennheiser nor the CS 300S's. I rate them only 4 stars because the rubberized cord is annoying and it's a bit too short.

5.0 out of 5 stars Wow, just as good as Super.fi 5 Pro!, February 7, 2006

I love the Super.fi 5 Pro. I've owned two pairs in the last few months, returned one because of irritation with UE. When I saw the new Senns were available I decided to A/B the two.

Well, for $150 less these guys are amazing! I have to push the volume up just a bit, but the tips are are comfy, the earpiece itself is discreet and easily maneuvered, and the sound is excellent - not too bassy like the cheap Sony IEMs. There's a soundstage! These are worth at least twice the price. My Super.fi's are going back to Headroom.

Test tracks:

1. "Naked Mole Rap" by Ron Stoppable and Rufus
2. "Le Jazz Hot" from Victor/Victoria
3. "Sentimentale" by Claude Bolling.

All three genres were marvelous. I can feel the piano keys tinkling. Buy these.

I have had plenty of experience with the Etymotics and Shure's. The Ety's are fine, well-matched to the iPod; the Shure's are, I'm sad to say, god-awful and shrill, regardless of fit - like viewing fine art under fluorescent light.

The Sennheisers sound pleasantly like the larger headphones in the line - muscular, full, strong but realistic bass, good presence and drive, clean frequency response and lots of musical detail. And, at this price, they are untouchable. I prefer them marginally to my Etymotics, which cost substantially more, and of which I'm still very fond.

My only caveat is that these come with asymmetrical cords and no clasp, which takes more fiddling-around and makes them a bit more awkward to use when in motion. Not convenient for use while exercising, though not impossible. I've gotten used it, and the musical pleasure more than compensates. Mine also did not come with any sort of cleaning kit or specs - cheaply packaged. The point is to take them out of the package, and what good is documentation for something like this anyway? No big deal. The Etymotics, for a bit more money, have comparably musical sound and are more adaptible for use while exercising, performing or otherwise moving around.

Unless you're dedicated to megabuck fitted studio monitors, stop here, buy these and spend the rest of your money on music, a charitable donation and something nice for a loved one.
