I would strongly recommend the BOSE in-ear jobbies. They're not technically "sound isolating" because they don't fit "into" your ear canal. the Bass response is fantastic as is the BOSE warranty. Sent a pair back due to a fraying wire sleeve (in all honesty user error) and they sent a brand new pair back in a box. you do pay for that kind of service in the first place though (£60 ish?)
