Color Name: Black
I have been in search of a pair of headphones for running for about a year. I have tried primarily earbud style designs. I have not tried in-ear designs because I do not like the sound isolation provided by in-ear. I feel this is a safety issue for running. The earbuds I have tried simply lack bass. Even though the specs of the earbuds I have tried show a frequency response down to 20 Hz, there seems to be a bass roll off.

The MDR-AS20J have very good bass. They have 13.5 mm dome type drivers as opposed to typical 9 mm drivers of earbuds. What also helps with the bass is the clip design. The clip design pushes the bud firmly but gently in the ear which helps with the bass response. Other earbuds slide out slightly which has a dramatic effect on bass.

The MDR-AS20J stay in place while running. You literally can just forget about them. They will not budge. The cord is also very light which helps with the bouncing of running. The MDR-AS20J are very comfortable for me though they are not adjustable. Some users may have fit issues.

These headphones have a very low impedance (16 ohms). That means just about any device can drive them to very high volumes, and at normal listining volumes, they will take less power.

These headphonse are weather and sweat resistant. Another important consideration for running.

These headphonse sound great. They have a balanced sound that does not over or under emphasize any frequency range. I used to watch movies in bed with a pair of high quality home headphones. The MDR-AS20J can hold ground even with my flagship headphones. I now use the MDR-AS20J for home listing in bed simply because they sound really good and they are so comfortable.

I have been enjoying the Sony MDR-AS207J headphones since April and have not been happier with a pair of clip-on/in-ear headphones. Earbuds (like those included with most mp3 players) do not stay in my ears, even with the addition of optional size adjusters, especially at the gym, so after several years of purchasing earbuds of every brand and type I resorted to the less comfortable but terrible sounding MDR-J10's until this model came out. The soft rubber is flexible and comfortable, and because it goes completely around the back of the ear, the headphones stay in place. I where mine everyday, going to work or class, and run with them several times a week and they actually stay in place every time, something no other in-ear headphone has done for me. Some other advantages to clip-ons vs earbuds is that these clip-ons do not block out ambient noise, so you will be safe when out and about. They are comfortable, even after several hours, and I have even worn them to bed several times. Also these headphones sound really really good, especially for $20 headphones. My hearing is not great after years of working around power tools, but I was pleasantly surprised by the sound quality, especially after the dismal MDR-J10s. While the sound is not comparable to a pair of high-end, noise canceling headphones, I find it rather comparable to the Sennheiser PX100s, which are a mid-range headphone. So for everyday use when out and about you cannot go wrong with these. Save the audiophile listening sessions for something nicer. After 3 months of heavy use, these headphones show no wear or frays in the cord coating, and have held up to sweating in 90 degree weather and moderate rain. Speaking of the cord, I have found the length (which is pretty standard) to be perfect.Read more ›

Like many other picky runners, I have been in search of the "perfect" headphones for quite some time now. The standard iPod ear buds fall out of my ears (as do most other ear buds) and it seems as though every other pair of headphones I tried required constant adjusting while running. That's not the case with these! I wore these during about an hour of cardio (a 30 minute run and 30 minutes on an elliptical trainer) and I never had to adjust them once. They didn't even have that feeling like they're about to fall off. These take some slight mangling to put on my ears, but once they're on, they're staying.

I'm no audiophile, but I feel that the sound quality is pretty decent. I've heard better and worse, but for a $20 pair of headphones, I think the sound is pretty darn respectable.

The only thing I can nit-pick with these is that the cord is too long, although it comes with a cord clip to resolve this issue. Overall though, I'd HIGHLY recommend these. I've tried numerous pairs of headphones and these are by far the best.

I purchased these headphones for my husband. He is a runner and training for another half-marathon. These are the first headphones he has found that actually stay in place even while running. He has tried all the earphone, earbuds, etc. out there. Even spent over $50 for some Bose earbuds but they would not stay in place even while he was walking or biking. These stay in place even while you're sweating and jiggling around. The speaker part of the earphones are placed better than anticipated. He loves the sound quality from them. He has a running buddy and even bought a pair for them. Even a small thing as the clip to clip to your clothing is a great advantage. We will continue to purchase these should he lose this pair.
