So I recently purchased a pair of Yamaha EPH-100 headphones. They sound terrific but I had to send back a pair after the left headphone suddenly went out. I filled out my warranty form and Yamaha replaced them fairly quickly. However, after about a month of use the left headphone went out again! I'm starting to wonder if it's my fault or Yamaha's.I typically listen to them when using my iPhone 4 and make sure my jack is clean. I always neatly wrap and store the headphones in the case making sure not to bend the wire near any of the connections (near headphones or jack). One thing that concerns me is I periodically use them at my schools library computers. Whenever I plug into these I hear white noise in both speakers, but I read in a forum somewhere that this shouldn't effect the headphones. As of right now the sound has "magically" come back to the left headphone but I'm not sure how long it will last and if I should send these back in again. Just to be more thorough, when I say the sound "goes out" the volume dramatically decreases in that headphone and the sound coming out it tends to be "crackly." As of right now, I believe they are back to full volume just as they were, but it's annoying not knowing if I'm hearing my music the way it should be heard. Most of you who are reading this are probably saying this guy is a noob and you'd be right (this is actually my first post), but if you guys could give me a suggestion as to what the root cause might be I'd greatly appreciate it! Thanks!
