Sennheiser OCX 685i Sports is part of the range of headphones introduced by Sennheiser and Adidas in the month of June this year. This one in particular features a rugged design which is apt for the purpose it has been made for.

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

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 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 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.

Awesome sound quality but the behind-the-ear piece keeps falling out when I'm jogging, and I cannot adjust it to my satisfaction. It's a minor annoyance.

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

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.

Great sound with great bass, excellent build and the white matches with the white i gear; Fit is very unique to each person but they seem to fit great and they stay on the ear during workouts

A bit pricey but you get what you pay for

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
