Im torn about this product. This one is twice as sturdy because it has 2 steel attachment straps per brace. You get what you pay for in life and the purchase of these was a good reinforcement of that statement. Just a louder-than-normal soft ticking whenever it would read/write - which was quite often. The red pair is very narrow and cuts into the soles of my feet. So final conclusion, the Index just gives a much better package and experience. I?ve spent £££ over the years on all sorts of fashion sandals but have never managed to find real comfort until now. No pain whatsoever. I can hear enemy players crawl up behind me from very far. So they are asking me to spend $10 - $15 plus packing material to send back a $50 headset thats faulty and, oh yeah, youll be without a headset for at least a month so youll need to buy something else anyway.
