Summary: I listened to these very carefully, and although I almost fell in love with them and their very businesslike appearance, I did feel like an idiot for wearing something that's all about its looks. Swapping between these and similarly priced earphones I found that while they're inoffensive, they were doing nothing out of the ordinary besides looking like a million bucks, and their writeup on Senn's site and the packaging seemed to back this up.
Summary: I bought these a few weeks ago, and like the other reviewer mentioned, they don't do anything too special. They are fairly detailed for an IEM at this level, and provide globs of bass. The inline iphone remote is especially nice. There is quite of bit of microphonics.
I will be keeping these as IEMs to use at the gym.
Summary: These are definitely good quality and do seem to be exactly the same as the originals the headphones came with. Having lost the previous large ones Id been struggling on with the medium ones moaning about how much better my cheaper headphones sounded. Now Ive got the right size back it transforms how they sound!
Summary: What can I say? They're exactly the same as the ones that came with my CX870 earphones, complete with the little bar in the middle that stops the diaphragm guard coming out and disappearing down your earhole. Which wouldn't be good. The only thing is, the set appears to also include several other types of earbud. However the ones I wanted (the ones shown in the product picture) seem to be in the majority.
Summary: Great headphones and whilst not worth the full RRP certainly worth the discounted price. I find these earphones, like all Sennheisers of good quality, pretty durable and comfortable I would definitely recommend them to anyone with an Iphone, centre button even works with Siri so thats an added bonus for Siri fans. Why not 5 stars? The earbuds come off too easy and the carry case is massive and not easy to get the earphones in.
Usual Sennheiser quality - but still a few niggles to iron out!

Summary: As with any Sennheiser headphones I have tried, I cannot fault these headphones! Bass is clear, but not overpowering, mid and high frequencies are refreshing crisp and clear. As far as looks go, they're not stunners - but are practical and comfortable. An important thing to note if you are used to Apple's headphones with remote/mic on the cable for the Right earbud, is that with the CX880i, the remote is on the other side - the cable for the Left earbud.
Summary: Gehen auch mal gerne kaputt nach knapp einem Jahr benutzung( einer der beiden Ohrhöhrer tot) und das schon das 2.mal!! Geniale aufbewahrungstasche mit magnetschließe. Da kommt keiner ran. Ton top und mikrofon / Steuerung iphone etc sehr durchdacht und qualitativ hochwertig gelöst.
