Summary: Having used Sennheier earphones for the past 5 years the quality of this product is second to none. The only improvement that is required is the sound control needs to be moved closer to the jack plug, while running you will very quickly get fed up with the sound controllers weight tugging at the ear plugs.
Summary: These headphones seemed a good buy at first as the newer model was £60 and these at £40. But within two-three days of owning them the newer model is now £30 and these even cheaper. Not impressed.
