Ok, it doesn't exactly cancel noise, I use it on the London tube and I can still hear every thing going on around me. It however fits into my ears comfortably, the main reason I bought this type of head phones.

I spent ages looking into which headphones to replace my defunct sennheiser pmx 70's (had them AGES!) and in the end took a gamble on these. Initially I was disappointed, not a fault of the headphones but my inability to get a decent fit in my ear canal with any of the supplied buds.

I bought these as a replacement for the older model MX680i, as my workout headphones (didn't fancy ruining my Bose pairs with sweat and Lucozade!). This time I went for the ear-hook and earbud combination that the OCX685i offers, as opposed to my old MX680i, which sat just outside the ear canal, and...

Reliability

With headphones I tend to focus on what they are intended to do. In this case, these are for working out and so there will be sacrifices in order to make them sweatproof, water resistant, etc.

over the ear clips were secure and comfortable

Great and comfortable fit; however, only after a few weeks the right ear piece stopped receiving sound.

I love it. This perfect for my workout. It is best in sound, Mid and high tone balanced very well by sennheiser, that it deserves no less than 5 stars and at this price it deserves more than five. It is very comfortable in ear too and very good in noise ilustration.

I don't have any headphones to compare them to, as these are some of my first good quality headphones. They sound great, they're pretty comfortable, if you wear them around the house, or just walking around, they stay nicely in your ear, however if you do something that makes you sweat, they don't...

Good sound; cheap

Bad build; headphone easily detaches from plastic arm; easily comes out when sweating (Probably fixable with thirdparty tips

After going through several pair of Sony headphones that kept dying after few months of heavy use, these Sennheiser headphone seem to be just the pair I was searching for. they are incredibly comfortable, well designed and are ideal for running.

after 10 mins into 10k runs crackling , volume changing up and down ended up taking them out gutted threw away packageing
