they have a great price...
someone who has this in-ears?
I have it.
I personally think it's a very good earphone at the 20 EUR + shipping it's selling for right now (I got mine at 15 EUR, but I don't think that'll happen again for a while).
Things to know about it:
So I guess what I'm saying is, they're very good earphones if they have the sound signature you like, and if you don't mind having to buy some third-party silicone tips. For me, they have a sound signature I really like.
Take a look at the mega-comparison thread from |joker|; the TD100 is reviewed. It's mostly an older version of the TD100 II. The only differences appear to be that the older TD100 had a J-cord, and the tips that came with them were really crappy; those that come with the TD100-II are just meh.
Hope this helps.
