Saw these on the Gadget show on telly last week - they reviewed them and that baldy bloke said they were fantastic! They poke right in your ears and silence the world around you, and have a good amount of bass apparently.
Anyway, here's the spec on Play.com:
The Goldring GX200 headphones are high quality intra-aural (in-ear) headphones for the most demanding ears on the move. Constructed from only the finest high quality materials these are perfect for the commute, travelling, the gym or on holiday, just plug into your iPod / MP3 Player or any portable audio device using the 3.5mm jack connector and enjoy.
The patented Comply canal tips (included with the GX200 earphones) constructed from memory foam, expand to create a comfortable seal within the ear. The tips are three times softer than skin and offer unprecedented levels of noise reduction and comfort. Escape the drone of background noise and enjoy your music in tranquility! Alternatively these phones are also supplied with soft silicone buds, in small, medium and large sizes - for optimum fit. The Goldring headphones boast a 1m cable and a stylish protective carry case.
When you compare the Goldring GX200 earphones you'll be amazed at the sheer quality of audio these produce. The What Hi-Fi? headphone review in October 2007 stated the GX-200s were "Bargain buds! ...open and enjoyable, with bags of bass to boot."
