Ok. I am compelled to post in here again because frankly this is just getting out of control.
I read all over Head-Fi that the Yuin PK3s are easily the best earbuds in their price range. Sound-wise, this is an indisputable fact. They beat the hell out of every other earbuds I have ever heard - particularly the Apple ones - including the comparable Sennheiser models which I A/Bd with my Yuins in a store. Love the warm sound.
But.
I have had no less than seven pairs of them break on me in the past three years. The longest any single pair has lasted me is about 6 months. Whether the cable near the plug begins playing up, or one of the buds loses its bass, or loses all sound altogether, they just DON'T LAST. After the first few pairs broke, I looked into some of the DIY ones on eBay. Some of them look beastly: huge, thick cables, heavy, solid metal plugs, etc. So I tried them. They broke too.
Given that the sound has been uniformly excellent on every pair of PK3s that I have owned, I don't think any of them were fakes. The DIY ones sounded 99% the same to me.
I kept replacing the PK3s because I figured, well what's another $30, it's still better than paying $200 for something that will probably require an amp anyway. Besides, I thought, if they only break once or twice, it's no big deal. But now, I have spent hundreds of dollars just replacing these $30 buds. If I had known, I would have dropped all that money in one hit on something INCREDIBLE, not to mention, more sturdy.
Having the track record with Yuins that I do, I never ever EVER EVARRR stuff them in my pocket. Whenever they are not being used, they get neatly (but not too tightly) rolled up and go into a sturdy, flat case. In other words, I take immaculate care of every pair of Yuins that pass through my mailbox, and yet they all invariably fail on me.
Surely there must be SOMETHING else around this price range besides the MX 580. Please help me.
