Sennheiser OCX 685i

Firm grip while on the move – Had this for a year or so and use it mainly when running / exercising. Maybe due to the design for tense movement, is not the most comfy headphone, l am getting a pretty hard feel in my ear when use for long, you need to take out to rest after long use, else is not bad overall.

Perfect sound quality – I don't know its original price, I just buy it 19$ and I am really satisfied with the sound quality. The second thing I love about it is the design that is suitable for running or doing sport. it is sweat proof and fits over-air. I use it everyday now.

Surprising sound quality – These headphones from sennheiser blew me away. I have beats headphones but needed something more sweat proof when I work out, and didn't want to ruin my beats headphones. The headphones 685i headphones have a rubberised covering which is said to be workout proof, and generally feel pretty durable. I wanted the over-ear design because normal earbuds will slip out when running. This over-ear design from sennheiser fits over my ears very comfortably and hardly notice them at all when i'm running. Now the sound quality is amazing, I subscribe to spotify and download very high quality music, and you can really hear everything in the music because the sound isolation is so good on these headphones. For the price they are excellent workout headphones.

The only drawback is also one of its pros. The over ear design is great when you want a snug fit while running or doing sit ups, but for casual listening the over-ear design is abit too cumbersome to put in and out while your out and about. build quality, sound quality, durability, perfect work out headphones need more colors, the blue and silver is pretty boring.
