It might be real, for all you know, but a bunch of things concern me about the listing; for starters, the 'Item specifics' says: Sennheiser, Monster, Sony:Beats.
Additionally, they don't do refunds (in case you learn they're fake), just 7 day returns. The warranty is pitiful at 6 months - a genuine IE80 is covered for two years. If I'm paying over $200 for earphones, I'd like them to last the warranty period. Would I touch them? Not ever. You could take the chance, I suppose. From the real pictures he showed via tinyurl, I don't see any glaring warning signs, but then again they're not very clear.
However, I can suggest an alternative - amazon.de has the IE80 on sale for just 199.90 Euro, or 33% off. That's about $320 SGD, much less than $590! I bought mine from amazon.de and had them shipped to Australia, and I can reassure you that although your proof of purchase receipt will be in German, the product is totally genuine. I was even able to claim official warranty (2 years) when my cable split after a month of use. It was as simple as a cable swap from the Sennheiser dealer in Australia, and all I had to do was show them the fault and the receipt (German, but still shows the price, source and date of purchase).
As Amazon is a Sennheiser authorised dealer, you should be fine buying them for about $100 SGD more from amazon.de. If you want an IE80 for cheap, I'd go there.
Yup, go for the M+ and also perhaps buy a pack of Complys for comparison (no doubt it'd be valuable to the community, as I know I can't really afford to replace Comply tips too often). Whichever fits you better or you prefer, I'd keep using! Good luck.
Hey iztis, I have experienced exactly the same problem, when I was first testing the IE80 to see if the bass knob actually worked. The good news is that it does - at bass level 5 there's an incredible amount of rumble, and there's evidently lots of air being pushed around by the driver... The bad news is that it does cause the driver to flex annoyingly when I insert them.
I listen to my IE80s on bass 2/5 and love them on this setting, but I for one can say my experiences are similar to yours - the bass knob at max results in driver flex. To my knowledge, driver flex does not hurt the IEM at all (if it does, claim warranty asap, but I've never experienced it) - it's just annoying when you insert or remove them. My Monster Turbine Copper Pros do indeed suffer from flex, the MTPC is notorious for driver flex. To this day they sound excellent and are still working fine after six months.
To sort of mitigate the flex with my Coppers, I try to open my mouth slightly when I insert them (it might look silly but I read somewhere it helps reduce pressure, and even if it does nothing it's a bit of a habit now anyway ), and also insert them by twisting. Rather than just pushing them in, I insert them with the strain relief pointing forward, and twist them gently counterclockwise towards the back of my ear as I insert them. Maybe try that? I haven't got many other suggestions for that...
Thanks dude, go to know that it's not specific to me. Thanks for your tips as well. Appreciate your help!!
