I have owned Sennheiser headsets for many years. They are excellent for music reproduction. When I needed to replace the Apple earpieces on my iPod4 I naturally chose the Sennheiser CX-270. However, the ones I just received are a great disappointment. Instead of balanced audio reproduction, both of the earpieces produce a very shrill sound with very little middle or low frequencies. Someone at the Sennheiser factory in China did NOT check this production run for quality. The box bears a lot number of 0420A. I suspect the whole lot will perform just as poorly. Amazon needs to Contact Sennheiser about the poor quality of this product.

I'm currently testing the CX 270s on a number of songs after my purchase. As mentioned previously, the bass on these is excellent - not too overpowering and very clean. But it's not just the bass, these headphones cover the whole range very well.

I've found that one of the best songs to test headphones on is The Hold Steady's "Stuck Between Stations" (the intro covers the mids and lows of rock quite well). On this song, these phones do as well, or better, than anything I've had. Kanye West's "Monster" (very bass heavy) sounds great! Joni Mitchell's "California" (guitar and vocals) is crystal clear.

They're not as good as the Sennheiser PX 100s - but they're very close. Excellent considering the size and price. You won't regret the purchase.

These headphones are really comfortable and have excellent sound quality. The bass sounds AMAZING! I've had lots of other ear buds but the bass never sounds any good. I would definitely buy another pair of these if I were to sprout an extra pair of ears!

The audio quality is pretty good, and the earbuds fit comfortably. I don't think they should be advertised as noise-reduction because they are no better at that than any other, and don't contain any noise reduction technology.

I bought this as a replacement for my Sony MDR-EX36 that I thought I lost. I read reviews saying the passive noise blocking was good and the bass was great.
I found my lost headphones today and I can definitely say that the Sony headphones blow these out of the water. Based on personal experience, I would recommend the Sony MDR-EX36. Same price range and way better bass and they really do block bg noise.

These headphones are really great. I'm not one for liking things in my ears but there is great comfort with these headphones. I was very interested in the "noise reduction" promoted and have not been disappointed. It is so great to plug these in, put them in and it doesn't matter what else is going on around me, I have a great listening experience. My compliments! Job well done! LDYREV1

First time buying Sennheisers...sound quality is excellent. I'm not a true audiophile but I was looking for a blend of quality, comfort, and sound quality without breaking the bank. This set has excellent highs and more than adequate bass. I listen to everything from classic rock to techno, so I wanted something that could handle it all.

Also, the noise reduction works quite well. Took them on a flight this past weekend and had no problems listening at my normal sound levels. Didn't have to crank up the volume to compensate for the outside noise heard on the plane. Very happy with the purchase. Just wished they included a case.
