Pros Great fit on ears, won't come out even running
Cons Poor sound quiality, terrible bass, volume too low
Summary Regret buying them, I can barely hear my music even with volume at the highest level. The fit is great but I get much better sound quality and volume with other headphones costing much much cheaper!
Pros Great Sound, Cool carrying case, Different size rubber inserts, optional ear clips
Cons Rubber inserts do not stay sealed, WILL NOT LAST MORE THAN 2 MONTHS IF USED FOR EXERCISE
Summary So ive had a pair of these for about 2 and a half months and for some odd reason the left earphone just decided to stop working. Pretty frustrating since i paid more that 30 dollars for them. :( will not buy again.
Pros The ear loop is the only feature of positive merit. It worked well to keep the ear piece in place during moderate exercise. This is the only reason why I rate it a 1-star.
Cons Productive is defective. I've had 3 units go inoperative in less than 2 weeks of use. In each case, the right ear piece just stopped working.
Silicon ear inserts do not stay sealed during fitness activties, contributing to poor sound quality.
Summary There is either a design flaw in this model or poor materials used for the audio components. The model is not designed as advertised for fitness use. As mentioned above, I had three separate units break and it was the right ear piece that went inoperative each time. Each unit only lasted for 14 days or less. In all cases, I was at the gym stretching and working out and there was no stress applied to the cord or ear pieces. I was listening to music and then the right ear piece went dead. I ended-up sending the first unit into Sony for repair since it was under warrenty. While waiting for Sony to send me a replacement unit (which took several weeks) I purchases a second MDR-AS40EX unit since I originally thought I just purchased a defective set. This second unit also went inoperative within two weeks of use and it was the right ear peice again that died on me. By this time, I had received the Sony replacement unit (third set) in the mail and I started to use it. Just like clockwork, the same defect occured in the right ear piece in less then two weeks. In all cases, I was using the head set for normal fitness activity and there was no stress applied to the cord or earpieces. I also used a damp cloth (just water) to wipe down the ear pieces and cord after each use.
Bottom-Line: Don't waste your money on this set You'll will end up buying a different brand/model after it breaks if you use it for any type of fitnss activities.
Pros Very comfortabe, good sound, great headphones for the price
Cons Bass - but you can increase bass with your ipod...etc...
Summary I was looking for headphones specifically for running since I'm an avid runner and I always used my ipod headphones with my ipod when running but they always kept falling out. So... I bought these. The fit is perfect... the light rubber that goes around the ear doesn't hurt at all and it fits perfectly into the ear with no discomfort whatsoever and best of all they didn't even fall out once! They stayed in place the whole time! The sound quality is great ... and even though some people might say the bass is weak, which I must admit it is compared to other headphones, you can just go on your ipod to settings > EQ > bass booster and you will have plenty of bass. Overall this was the perfect pick for me and I would definately recommend it, especially for the running/work-out enthusiast.
Pros * Sound is reasonably good
* Very little cord-noise
* My most resilient phones to date
* Useful short cord-length + extension
Cons * Sound is not quite as good as my old Nuforce buds
* Comes with a silly, bulky cord-case.
* Comes with a fiddly lapel-clip that doesn't work well and can pinch cords if you're not careful
Summary These are my favourite "blue jeans" buds. They're dirt cheap and have much better sound than their price suggests. The insulation plastic is slightly waxy-feeling and carries very little cord-noise through to your ears (a BIG problem with my old Nuforce buds). The removable over-ear hooks are comfortable and significantly ease routing the cords over your ears to reduce even more cord-noise.
So far they've had the most long-lived cords of any buds I've owned (Most have died within a year).
The cord is short, which is good if you connect it to an audio device in a shirt-pocket or on a lanyard or arm-band. There's an extension cord for longer runs.
They have wax-guards to keep "ear-salsa" out of their inner workings.
They're stylishly designed and feel really great. The moulded connections are about the least bulky I've seen .
They have the usual 3 different sizes of soft-tips and ear-hooks as you'd expect. They also have a rather large "spool-type" cord-case, which strangely doesn't seem to have quite enough room for the buds with the extension cord attached. There's also a lapel-clip that never seems to do a good job of clipping to clothes, but is really difficult to move-around along the cord. If you're not careful you can even "guillotine" the cord inside the fiddly cable-routing of the clip.
