I have to say this thread is a bit crazy. :-P Don't get me wrong, a lot of points are extremely valid, and I might be reporting back in a few days that I have three completely different sounding tenores. However, we're talking about a few people of which only a few have any variances. What would people say if we did a poll and found that 3,000 other people have absolutely no problems. That would be less than 1% of problems, which is superb quality control. I'm not saying I believe that is the case, but we just don't know, and for tyl to dismiss it that quickly is pretty sad in my opinion. He's only hear two pairs in his entire life and he immediately assumes it isn't worth reviewing. Add all this together and before you know it nobody wants to touch the tenore.
I for one am very happy someone recommended them to me, and they're the best IEM i've ever heard so far. If someone reads this thread and is turned off because of the issues that would be pretty sad. :-o If we get some more numbers and find that the data shows this is a very common problem, then it's worth stressing the issue. Until then, why don't we all just state the problems that we have, what you have done to try and fix it, etc. etc. And leave it at that. I just don't think we should go around talking about all this bad QC and incredible amount of variances, etc. etc. when there simply isn't enough data to support it yet. These are real people having real problems with their tenores, but I can show you the exact same thing with every IEM ever made on the planet. Go look at amazon, there are always negative reviews about this failure or that failure, usually with at least one recurring theme, but once the product has been out and has data, there is usually a substantial positive section of reviews that outweigh the negative. If I read a review on amazon of a wire failing on the er4s and there were no other reviews, i would take it with a grain of salt. That's all.
We should try to collect as much data as possible if we want to show they have QC problems. Gnarlsagan has his sets and that's a start. I'll give you a review of my next three pairs when they arrive. And maybe we can start a poll of people that have had issues vs. working sets. It's easy to do on the thread, and we could at least start to see some sort of numbers. As long as everyone is honest and only polls in if they own the tenore. :-p
Those are my thoughts on the issue anyway. On another note, I can say that my pair of tenores seems to be extremely durable so far. I wear them over ear a lot, which I'm not sure if it causes a bit of sideways strain on the cable or not where it meets the housing, but it doesn't seem to bother it. I have fallen asleep listening to them twice (I just can't take them out of my ears! ha) and woke up with my zip and tenores under my body. Who knows how much they were yanked around, but at a minimum they were yanked out of my ears twice. Lastly, I've dropped the zip a few times (3 maybe) and it has fallen and then yanks on the tenores as it fell. The zip is pretty light, but it still pulled them enough to irritate me having them yanked while in my ears.
With all of that they seem perfectly fine so far. Not exactly a stress test per se, but that's actually a lot worse than I normally treat my earphones. It's just that I really haven't wanted to stop listening to them, so I've had a lot more listening time in and I listen while multitasking more as well, so sometimes I drop the damn thing or sleep on it. haha :-P Just sayin'
