Question: I usually listen to podcasts (spoken voice), while running or walking outside. How good is noise cancellation? Thanks!
Document: Also, since they're not wedged in the ear, if there's a lot of outside noise you have to press them against your ear to hear very well. (I listen to audio books and often the development landscapers are cutting lawns, etc).
These are very comfortable for me as one who can't get anything to stay in my ears. They slip off and on my ears very easily and stay on well when moving. I haven't jogged in these yet so don't know how they would work during exercise. The sound quality is also very good with a crisp sound without having to have the volume all the way up. I used these on the plane and while they aren't a noise blocker, I was able to shut out outside noise and relax.
I love these head phones. I cannot put earbuds in my ear, so these are perfect to wrap around my ear and listen to my music at work. The only downfall is they are hard to adjust to stay on your ear. They work well if you are sitting or moving slowly. Not the best for running, unfortunately.
I listen to AM radio at work, 6 days a week, for between 6 to 10 hours per day. I only listen in my left ear as I use it for background noise more than anything else. The only reason I purchased these is because after over two years with another brand the cord is starting to make the sound cut in and out.I've worn these for one day and can't stand them.PRO: The sound is fine. It's somewhere between 'adequate' and 'really good'.
I occasionally listen to the radio via Sony Walkman while cycling and wanted a set of earphones that:1. Wouldn't interfere with my helmet2. Would stay on and not keep popping off every time I turned my head.3. Would NOT completely block out the enviornmental noise as I also want to keep apprised of what's going on around me while cycling for safety reasons.I had tried other types of earphones including over-the-ear varieties and in-ear varieties and they just didn't stay in.
I have extremely small, sensitive ears, and it's difficult for me to find headphones that don't hurt. These are pretty cheap, and do the job well. I can listen to music for hours without any pain. This is the second pair of these that I've purchased - I keep one pair at home for running with, and one at the office for listening to music while I'm at work. I've had the first pair for over a year now and they still work and nothing is broken on them.
I bought these to listen to music/podcasts at work so I would be using them for several hours at a time. After maybe 4 minutes of use I noticed my ears hurt and when I took them off my ear cartilage was squeezed through the tiny opening and it was awful. They were also BRIGHT RED from being squeezed. I don't have the daintiest ears by far, but I don't understand why the speaker and wrap-around parts are so big that they leave no room for your ear!
I'm usually able to adjust them periodically so it's not too bad,  but they get uncomfortable especially if I'm wearing glasses at the same time.Overall, I like these earphones and they are definitely good for the price.
The headphones are good. The sound quality with the price is very nice. But, I usually wear it when I sleep, so it is a little bit to thick for bed. It is so thick that it hurts when I turn around. But, it is still a good pair of headphone if you don't wear it for sleep...
Since I wear hearing aides, I needed headphones that are over the ear and not in the ear. Wanted ones that are light and fold up to be easily portable. These headphones meat all those needs.Of course, the most important factor is the quality of sound. These are very good on that factor. I mostly use them when walking around with my HTC one phone and whether making calls or listening to music, I'm a happy camper.
Answer: I use them at work and I have a very loud, annoying co-worker that they help me tune out.  They aren't noise cancelling per day but they do work really well.
