Unfortunately I know you've mentioned before in a post. That you are from the UK I live in the US. So I'm not sure what is available to you. over in that part of the world. If they make "Sentry Deep Base Headphones" over where you live I'd highly recommend them even though they are not earphones but instead great quality headphones
Sentry Deep Bass Headphones are about $10 USD at stores like Big Lots and Walmart. they are great quality I've had one of mine for about a year and a half, and they are still great even after lots of abuse. They come in White or Black color, they are in stereo and sorta sound like surround to me.
I love them except their kinda hot on the ears to wear in the summer time. But as far as Earphones go the better ones are the ones (for me) are with the plugs, since, the ones you are talking about. hurt my ears and lack quality due to the position of my ear holes
Sentry Deep Bass Headphones model number HM960 or HM961
