I have had these for a little while and they sound great and have held up better than the Jbud J3s I was using before. I commute on a motorcycle everyday and I where these under my helmet. The everyday putting and taking off of the helmet, plus all the wind blowing parts of the chord around, and they get yanked on every now and again when there isn't enough excess cord. Despite all that they are still going strong, and I don't see any abrasions or tears in the wires. Best affordable headphones I've had.

I bought these earbuds because I listen to music when I work out at the Y, and there are ALWAYS very chatty women or spinning instructors screaming instructions....very distracting. My Shure earbuds did not blot out the sound, and I didn't want to wear my heavy Bose noise reduction headphones, because I sweat a lot. These worked great, cancelling out 90% of the noise, even the screaming spinning instructor. And, the sound was far better than the Shure buds that cost 3 times as much. I needed to turn the bass way down on my mp3 player or it was actually too much. The buds come with 3 sizes of rubber earpieces, and the only negative might be that I don't know if you can replace them. These are a great buy. BTW, I listen to classic rock while working out...Genesis, Allman Brothers, etc.

This is my first use of sennheiser products. It has really clean and enough bass response. Sennheiser makes me to buy their products more. I own dr.dre studio headphones which has really heavy bass response. It feels like in the club. For 20$ CX280, It doesn't go wrong with it.
Pro: Clean sound and enough for daily listener
very comfortable ear buds that i've owned.
Even forgot to have it in ears

I got these on shenzhenaudio.com for a good deal, so I decided to try them. They block out noise really good and they sound great for the price, but dont expect Beats or Bose quality. Overall, I am highly satisfied and may stick to buying Sennheiser's from now on!!

I purchased this for everyday use and am very happy I did. This set of earbuds produces very rich sounds, almost comparable to my Bose headphones. The first thing I noticed after placing them in my ears was that the silicon ear pads isolates most ambient noise - plus they feel very comfortable. When connected to a music source, they produce great full-range sound. My only compliant would be that the slider on the integrated volume control doesn't have any ridges which makes it difficult to slide. However, I would definitely recommend these.

I bought these headphones as replacement for my old Sony's. What a difference! I use them with my iphone 3GS and the sound that comes out of them are nothing short of sensational! Great bass, treble and mid range output. Once you have them on, you cannot hear any else but the music. Also great for phone calls.
Worth every penny I invested in them. Got a great deal on them on shenzhenaudio.com website
The only con I can say is that it's difficult to differentiate the left and right ear on the headphones, you have to look real close on the back of the headphone and you can see the L and R markings.
I highly recommend these to anyone who is interested in getting the most out of your music device. I am extremely satisfied with them. I will surely get another pair!

Awesome best describes these earbuds. When I first listened to my itunes through them I immediately started hearing sounds in tracks that I did not hear before. The bass is unbelievable for the size, not overpowering but just enough punch. The rest of the spectrum is crisp and clear. I originally bought these exclusively to work out on the treadmill/elliptical. Great motivator. The sound was almost as if I was at home rocking to my stereo. At home I only use my Dr Dre headphones now if the house is extremely noisy. Not to undertstate the noise canceling ability of the earbuds. For the money you can't go wrong with these babies. I had them for about a year now and I would recommend these to anyone looking for great sound at a reasonable price.
