I was looking around for new earphones to replace my Creative EP630. I saw the Panasonic HJE70 for £17.20 on Amazon when other places on the net are asking for around £50 minimum. The audio enthusiasts on here (if any!) will probably know this is a bargain, but for those that do not know too much, I will post what I found out from research/experience...
In terms of sound quality they are better than the EP630 (BTW the EP630 are supposed to be identical to the Sennheiser CX300) and also the Sony EX71 (which I have had the pleasure of owning as well - till they broke).
I have read about people comparing them to the new Sony EX90 (£56 on amazon), which are better than the Panasonics but many people on audio forums find them very comparable or only slightly better.
I don't post too many bargains here, but when I do, I believe them to be true bargains... enjoy
