Fell apart two months.  Speaker fell off the wire and the ear buds no longer work.  Strangely, i had another pair in black and they have worked fine and i have had them a while -- they stay over my ears when i'm working out, which is why i got them.  Maybe we just got a bum pair.

I purchased these about 6 years ago,2pair because both of my children are heavily in year round sports.....These things go everywhere with us. They STILL work fabulous and have even been on all night sometimes. I would contact the company; maybe you got a faulty pair.  I LOVE mine...

I had a pair of these in black so I new what to expect.  Can wear them for an evening.  Can't ask much more than that.

This is my second pair of these and I have been quite pleased with both.

I have a pair that I purchased at a local dept store a few years ago. I wanted a replacement, but could not find them locally. They have lasted well and have stayed very comfortable.

I bought two pairs, one black and one blue. Both fit well enough, but I had measured each foot several times and matched the lengths to the size chart .  Being made of a synthetic material, they won't last all that long, but I am enjoying them now.

i really like these, only bad side is my previous pair stopped working after 3 months of use (running) i have reviewd before and said the same. that was over a year ago, i seen them on sale, so i am trying again... i got about 2 months in now, (but since its winter, not alot of running yet). i am crossing my fingers... if they fail in  < 6month, i will change my review

I have not had them that long but they seem to work very well and I think they are very good value. I have had no issues. I wear them most every day and they have performed very well. Battery life has been good.

I have a set in black as well and bought these again with a new bike.  They're heavy, but they work extremely well.  I've trashed the black ones and they still work flawlessly.

I have bought these and the Black pair same glove just different colors.  Just not sure why these are almost twice as much as the black pair.

I need black socks for work.  My work is not that strenuous, but I find that many socks get holes in them through just the passage of time.  These socks seem perfectly fit for just existing through a few washes.  I am more than pleased in how they are holding up in regards to remaining black (as opposed to turning gray as so many socks seem to become.)

If you need something else in regards to your sock needs such as warmth or sweat retention these socks are not for you.  However, if you simply need a standard black sock, these socks are holding up quite well.

I received the socks in a timely manner.

Not sure why but after wearing them a few times, one shoe is black and the other one is now a dark grey!

My wife ordered these and the fit is fine but the black pair make the soles of your feet black after a while minutes.  Not good.  She has brown pair too and those are fine.

I have a pair of 541s in black that I ordered only a few months ago after doing research into this type of cut. I was prepared to order another pair but I thought I would get a different color the 2nd time, because I liked the black ones so much. I ordered the "rigid dragon" in the same style and size, and it did not fit at all. Holding the pants next to each other shows that the "rigid dragon appears to be at least two sizes smaller than the black.

I buy these cartridges about once or twice a year, and I like them well enough to keep buying them.  I have had two of the cartridges go bad. . .in that they would not work properly after installation.  But, the company always sends out a replacement and you don't have to send the bad one back.  So, I always keep at least 2 blacks on hand, so that I am not left without any ink.  They are much cheaper, and the inconvenience of an occasional bad one is why I am giving 4 stars.
