Comments about Sony MDR-AS20J Stereo Earphone:

I bought these about a year ago and love them. They were great for the price and stay on well. But over time one earbud got to have a lower volume. I think i'll shell out the money for a more expensive pair this time.

These are the best sport headphones I can find for the money! Great sound quality compared to Skullcandy, JVC and other price competitors and the headphones comfortably stay in my ears when I'm active. I prefer these any day over ear buds that constantly fall out and give me a headache after prolonged listening.

Comments about Sony MDR-AS20J Stereo Earphone:

Not only does the right ear bud short out as soon as a drop of sweat touches them, they constantly keep coming out of my ears. This happens EVERY time I work out. Since I work for a living, I don't have time to keep going to a store to buy new headphones, therefore I've become an expert on how horrible these are because I'm forced to use them!! I look forward to the day that I can hear my music while I workout.

Comments about Sony MDR-AS20J Stereo Earphone:

I ride my bike to/from work 13 miles each direction every day and I like to listen to podcasts or audiobooks on my iphone and I occasionally need to take a call or participate in an early morning meeting. These are ideal for the podcast/books use-case, but since they don't have headset capability they really don't work for the phone -- I've tried an accessory that plugs in-line and handles the phone part, but it doesn't fit well in my bike's iPhone case and it's really inconvenient. I'd love to have these with headset/mic integration! They're really the first headphones I've found that I feel safe using on the bike, I can hear the world around me but it doesn't drown out the podcast/book sound.

I bought a pair of these and after about a month of use I noticed the right earbud began to lose sound quality and is now completely inoperable. I will not purchase these again and would advise others not to as well.

Comments about Sony MDR-AS20J Stereo Earphone:

As opposed to most negative reviews, the left speaker still sounds great. It's the right one that went dead. I guess this shows that not all left speakers are bad.
Also, the clip meant to hold the cable to the shirt, sleeve, etc. allows for the cable to move within a guide. Well, a quick tug on the cable proved how useful that is: the cable got stripped, separating the wires inside. This was after the right speaker went dead, so it turned what was already a bad experience into a terrible one.
I'd have expected more from Sony, and was disappointed instead. Sony - if you're reading this - the experience with these headphones made me reconsider buying a VAIO laptop, and I went with Dell XPS instead. Digital camera? Now a Canon. Yeah, building a brand name starts with the little things.

i've had two pairs of these over the last year (i returned the first pair and got a second as a replacement), and the left earpiece has gone mostly dead in both of them. i'm not particularly hard on them. so i don't think the wires are getting damaged.

Comments about Sony MDR-AS20J Stereo Earphone:

Do not buy these headphones. I've purchased two pair and neither lasted more than a month or so before the right speaker failed. They should pull this off the market. They are a waste of money.

This is the second set I have purchased and now it like the first has the right side playing at only partial volume. Maybe some kind of short or the sound device internals are failing. Two sets, two failures and other reviews citing the same thing

Comments about Sony MDR-AS20J Stereo Earphone:

I bought these headphones last April and I have to say that these are the best pair of headphones I've ever owned. I bought these after my two pairs of Skull Candy earbuds broke. The sound quality on those were great, but they were terribly unreliable. My brother had a $100 set of earbuds from Bose, and like the Skull Candies, they broke in a short period of time. I put these on and WOW!!! The sound quality is better than both the Skull Candy and the Bose earbuds, for a fraction of the price of the latter. I would buy another pair, but at this rate, I think these will last me a good 10 years. Simply amazing! I don't know how anybody could complain about these headphones.
