Excerpt: I was excited to get these headphones for my hikes with the dog in the woods. I liked the idea of the inline remote/mic. The tone was too high for my liking, therefore not able to wear. I guess I have sensitive ears. I did like the choice of ear tips, I required the smallest in this case.
The iPhone buds fit in my ears ok and the sound is ok but I thought I would treat myself to a much better pair of headphones for

Summary: I'm not sure if there aren't two different products with the same name out there. The headphones I bought were to replace standard iPhone buds and I was expecting a really, really big improvement.
Good for Apple users who have the right sized ears for a proper fit - for everyone else its completely hit or miss

Summary: I bought these to replace my CX680s which had a few design flaws of their own over the years and having a several replacements through Sennheiser's excellent 2 year warranty (as long as you purchase them through an approved dealer).
Summary: Shame, after paying so much of money you still get something which is not up to mark. It keeps popping out of the ear, i have tried all three sizes came with headphones, after 10 mins of run they start popping out...Bad decision to buy them...don recommend this product at this price
Summary: Tried out for the first time and within an hour the remote started to activate the voice control on my phone without me pressing any buttons. I'm assuming this was caused by the remote getting wet with sweat.
Not suitable to large ear holes and sports that involve sweating.

Summary: I'm used to buy sennheiser, usualy i would recommend to buy, but this sport model is a disapointment. The first sound impression was, where are those deep bass i'm used to, then the ear budd that dont stay in place even when im still.
Summary: The headphones have a good sound quality however they are not really suitable for running. The volume control is really annoying as it jumps around and pulls the headphones all the times. Using the wire clip did not really help. Sending it back.
