Question: Good for Walking? I noticed right away that when using these for exercise walking, I hear my feet striking the ground as the sound travels up my body. (I also can hear my heartbeat.) It's very distracting while I walk to hear such noise from my walking. Thump, thump, thump, etc. Anybody else have this problem?  Otherwise, I'm liking the sound (while stationary) a whole lot.
Document: One problem is that when you walk or run on a windy day, it sounds like the wind is whistling through the stays of a ship at sea... very annoying. Also, you have to secure the wire close to your neck by running it under your shirt or by other means; if you have a long length of wire flopping around you will hear a thump each time it bounces around.The wire length of the earbuds that came with the iPod is 45".
First of all wtf i ordered a Sennheiser cx 300B but got the regular cx 300 no B with it. Did this happen to anyone else?? ?Great ear phones. You gotta have the right size earbuds on to fit your ear perfectly for maximum bass. I used my old sony 71 style ear buds and put them on the Sennheiser 300(B). I could hear my notes in my songs than the Sony's 71 series with better quality. Also you need good quality songs to have good quality sound.
Overall, I am very disappointed. I am taking them back. More because of the cord noise than anything else. I think for the money I paid, the sound is about right. If the cord noise were not so pronounced, I could definitely live with them for $59 even with the weak mids. Hey, I know these aren't high end audiophile buds and I'm not an audiophile. But I know what sounds good to me.
Quality of sound is excellent, but I found that with the noise canceling feature of the buds fitting so well into my ears that there are audible thuds when my feet land on the ground while I jog while listening to music. I'm trying different sizes of the buds and positions in my ear; some are better than others, but nothing has worked completely so far. Write me at [...] with suggestions!
I've been using the CX300s for about a week and my only complaints are the wire-brushing noise previously mentioned on other reviews, and the asymmetrical cord length. Otherwise, these rock for the price! I live in Chicago and commute to work on the El train and these babies keep out all train noise, people talking on their cell phones, etc. I definitely recommend these to anyone who hates the default Apple earbuds but doesn't want to spend over $100 for Shure.
a draw back that i have noticed is because they work like earplugs you can hear yourself swallow, chew, drink, etc...plus they tend to build up pressure which can start to hurt. i found that when i put them in my ear if i twist back and forth as i do it relieves the pressure. I also plan to try out the 4 extra size/type rubber ear cushions that were included. also people complaining about static i believe were hearing the cable rubbing against thier cloths.
This was my first I considered performance earbuds, they definitely lived up to their reputation. The sound quality was excellent. I hated the "brushing" noise, I noticed after the split point from the wire, the right side didn't have this problem, but it still remained on the left side. I am not a big fan of the asymmetrice design of the wire but I will just have to get used to it. Aside from these two points I love them and I strongly recommend them.
I bought these to replace a pair of Sony MDR-ED21LP's that died on me after a year or so of usage.CX300 Pros-Sounds great-Gives good bass-Offers good sound isolationCX300 Cons-They breakI used these daily and have them wrapped around my mp3 player carried in my pocket. I also used them when I cycled. Be very gentle with them, otherwise try something else.
If there is any kind of wind I get a wooshing noise through the cups, perhaps my ear canal is too big even for the large cup, but I have to imagine this happens to others too. It's like listening to a shell on the beach. This causes the largest listening problem for me, the wooshing sound is distracting.Bottom line however, I would recommend and purchase these earbuds again in a heartbeat. For the price you can't beat them. Small lightweight, comfortable and sound great.
These headphones are great, they are even better than most noise reduction headphones, I bought a sony that requires a battery but even with the batteries I can still hear noises at night. I use the Sennheiser to go to sleep and they are comfortable and they dont even have batteries to install. I really don't use these headphones to exercise or to walk around with. I use the sennheiser to go to sleep, I listen to soft relaxing music while I go to sleep. They are really great
Answer: BW:I have found a way to fix this!! Try winding the cords over the top of your ears and then into your ear canal. In other words, approach your ear from behind, pulling the cord over the top of your ear, then pop the bud in. This as opposed to just putting them in and letting them hang down, where they transmit movement sound rught into your ear canal.  This breaks  the 'resonating' sections of the cord, and stops most of the noises from reaching the earpiece. Works pretty good.
