Q & As

Rated 3.4 out of 5 by 5 reviewers.
Rated 1 out of 5 Sound is good but they won't stay put The sound quality from the headphones is good, as long as you are not moving about. They are described as 'Sports' and I bought them to use while running and they will not stay in my ear, they do not have any real adjustment or ability to change shape except for supplying 3 different size ear buds. So if you need headphones for sport with any sort adjustment for grip probably best to try something else, unless your ears are exactly the shape suited for Sennheiser products (which mine aren't) 21 December 2014
Rated 2 out of 5 by Great sound quality, rubbish fit After extensively researching my options I purchased these headphones through JLP. The sound quality is really impressive, and the design appealing, but no amount of fidgeting would make them stay put in my ears. Eventually I called up Sennheiser who advised me to return them because the one-size-fits-all design apparently doesn't fit all... 23 August 2014
Rated 5 out of 5 by Great headphones for sports use I bought these headphones to use while exercising outdoors and at the gym and would highly recommend them. The cord is a sensible length, the ear buds are comfortable and, best of all, the sound is really good. These headphones also come supplied with a storage pouch which prevents the wires tangling inside your bag. Brilliant value for money. 09 August 2014
Rated 4 out of 5 by It does what it should An item which has performed more than adequately in the gym and has been washed with no ill effects too date. Simple to use and performs to an extent that the gym user really should have no lack of sound and quality of reproduction for a product at this price level. 07 January 2014
Rated 5 out of 5 by Excellent all -round headphones I did a lot of research before buying these and have been through a lot of headphones in the past. For me - I needed to find the right balance between a great sound, and a design that would stand up to the rigors of being used whilst running and at the gym. My verdict - is that these are brilliant headphones. The sound is great - good bass and range and certainly up there with some more expensive non sport headphones I've had in the past. Design wise - these hold in my ears well - on long runs they don't shift a bit. I find them very comfortable. For me, they strike the right balance between isolating the sound and allowing some outside noise in - useful for when you're out and about running near traffic. I'm also quite happy to use these in a non-sport environment. That is - they don't appear overly sporty. 22 November 2013
