Q & As

Rated 3.7 out of 5 by 6 reviewers.
Rated 5 out of 5 by Excellent I bought these for my wife for use in the gym. They have great sound quality, don't move and are pretty good at shutting out the usual awful gym music. Must get myself a pair. Excellent JL click and collect, available instore within 24 hrs. 09 January 2015
Rated 1 out of 5 by This is not stable Maybe it is just me but these were not stable for me and kept popping off during my workout. Sound quality not so good. Plus does not have a remote controller so cannot adjust the volume, nor take calls. It is really annoying. 23 December 2014
Rated 5 out of 5 by Excellent value headphones that deliver as promised Great sound - loved the different sets of earpiece sizes, as I could have the right ear one bigger than the left. absolutely does the job!! 29 July 2014
Rated 5 out of 5 by Excellent quality A fantastic set of headphones which are of a high quality. Exactly what I needed for my gym sessions and running. 21 May 2014
Rated 5 out of 5 by Comfy, good sound quality for the money No problem with fit in my ears. After a bit of a fiddle with the "fins" they fitted snug enough to survive a very wet 4 mile cross country run without falling out. Sound quality is pretty good, it is a little bass heavy but I like this in workout headphones. Overall build quality looks good and they come with a 2 year guarantee so the manufacturer must be pretty confident they will last. 27 March 2014
Rated 1 out of 5 by Not a good fit, for me I am having to return these, as I just can't get them to fit snugly into my ear. They just fall right out. I have tried all the different sizes of earbud that come with them. I guess it depends on the shape of your ear, as I read a lot of reviews before I bought them and people seemed to like them. I would also say that the instructions were rather minimalistic. I thought there might be some fitting instructions, but there weren't. 10 February 2014
