5 Highly recommened and better than JVC HA-F240 Gumy Air5cooter | 26/04/2010 | See all 5cooter's reviews (2)I bought these after trying Sennheiser CX300 ear canal phones which were uncomfortable, needed very precise fitment to hear any bass and even then didn't like the sound quality. When I tried these I immediately liked the sound quality and comfort. Don't expect to block out much background noise. I liked these so much I bought JVC HA-F240 Gumy Air thinking they would be better still. They feel a bit more secure but the sound quality is not as good. With no high street outlets offering the chance to try these products the consumer has to buy to try these products. Save your time and money and just buy these.
