Sennheiser CX495 v's CX475 v's CX300
Having read your 5 star review of the Sennheiser CX495 in ear phones i feel tempted to purchase a pair. Just had a quick look on the internet and i've seen that Argos are currently selling the CX475 at £19.99 (half price). I currently use the CX300's.
So basically will the CX495's give me a noticeable improvement over either the CX475 or the CX300, and if so would the improvement be worth the extra £20 over the CX475, or worth the £40 over just sticking to my current CX300's ?
