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

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.

Its one of the best products if you want to go for a product moderate-high sound output, with good quality. The ear plugs are quite comfortable, the wires are pretty long. Go for it if you are not too concerned about bass.

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.

The ear pieces feels reliably constructed and due to the strain relief devices they won´t brake in a hurry. The cord is rubbery giving some

Very pleasing sound that still has sufficient bass for training; Handy remote control on the cord and supplied cleaning tool for the earphones

Hard to get them to stay in the ears

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.

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.

The control box failed after 3 runs. Richer sounds were great and replaced the unit without question at my convenience. Great service. New unit so far so good.

Listening to music during workouts can be more work than it's truly worth. I can't explain the number of times that I've had to put aheadphone back in that fell out during running, whether it be on a treadmill or outdoors. The result only adds to the annoyance and frustration that many experience d…

Extremely comfortable, sweat and water resistant; Cable is long enough for just about any physical activity

Sound is decent at best

Superb sound clarity. You will feel that you are flowing with the music when songs are being played... Make is OK only as the ear support os nothing but very thin rubber.. The chord can be made bit more long... Very less out side noise interference.. Its value for money..

Comfortable; Good Bass; Good Value; Great Sound; Lightweight

Flimsy Construction
