Love them!

I have had these headphones for a little over a year now, and haven't had the first problem with them. My ears are oddly shaped, so I normally can't use in-ear buds unless they have over-ear hangers. I also wanted some that I could use while working out. These are perfect for working out because they're waterproof and pretty much stay put. They tend to slide out of my ear when I'm talking, but all ear buds do, so I can't complain about that. But the interchangeable sizes make them stay put mu...

The sound is great for such inexpensive headphones. I've seen some reviews here that say the sound isn't great, but I'm a minor in audio engineering and often use these to evaluate my music while I'm on the go. Of course they're not up to the same quality as the more pricey Sony headphones, but they are exceptional for ear buds. And I've recommended them to some classmates who don't have the funds to go out and buy really nice headphones. I give them two thumbs up.

Broke my iPod :/

I just got the new Nano so I figure I'd upgrade the headphones. Well, the first couple days with it were great, but gradually the music started to distort or sound muffled. I would jiggle the plug that goes into the jack on the iPod to get the sound to come out right. If I moved it to the perfect spot and held it there it would play OK. As time went on I couldnt get music to play correctly at all, even with the stock iPod headphone. The Sony's had messed the connectors up so bad. Moral of the...

Moral of the story: the design is pretty good and they sound GREAT(when they work right). Keep in mind I've had these for less than 3 weeks. But DO NOT USE WITH NEW IPOD NANO!!!! Now I'm back in Iraq and stuck with a broken iPod and useless headphones..... guess things could be worse.

Love Them but they break

By

from Raleigh, NC

this was my 3rd set. I love them but will not keep buying them. This last set lasted less than 3 months before the sound stopped coming from the right ear piece. None have lasted past 10 months.

very disappointing

By

from Chicago

I have small ears so I liked the design - three sizes of ear hangers and rubber earbuds - but the sound quality was very poor with minimal bass response. Not at all what I'd expect from $40 headphones. I can't rate reliability since they are being returned the same day I bought them.

Pretty Good...when they worked

By

from Chicago

Enjoyed these buds well enough while they lasted. Sound was decent and ear clips allowed me to run with them in. But... while running constantly had to put buds back in my ear (no matter which size tip I used.) Then... 9-months in the left bud just died. These were well cared for and show no apparent physical damage, but one day the left ear just stopped working. 9-months is nowhere near long enough life for $40 buds. Would not recommend or buy again.

My runs last longer

By

from Scottsdale, AZ

I hate to be so blunt, but I've gone through 3 pairs in under 9 months. I'm avidly loyal to Sony, but this last pair just went out on me DURING A HALF MARATHON. This is just sad. There should better QUALITY. Please these are good for maybe a dozen uses. DO NOT BUY. FACTS: 3 different pairs each only lasting about 3 months each Problem: One hear bud will usually just go "out" extension wire gets caught and detaches VERY POOR QUALITY. I used these for working out and running.

Great Design, Poor Sound Quality

By

from deGraff, OH

Love the Design, Stays in ear, Don't always have to be readjusting them. But the sound is awfull, NOT loud at all. Have a $5 pair of Panasonic ear buds that are 5 times louder. very disappointedwith these ear buds for the price I paid for them.
