Sound Isolation & Noise Cancelation Technology

Hi all, I’m looking for a new pair of sound isolating earphones under £50. Had a pair of Sennheiser CX300 and 500’s but not impressed (terrible stethoscope effect thru the cord). Any suggestions would be very welcome. Thanks in advance!!

i realy liked the sonys (not sure of the model) i know they cost about £30 and they have the little rubber ear buds

also try checking out any earphones by SURE

hope this helps
