Headphoneus Supremus
That was a great review. I generally stay away from any "in ear" design earphones as they never feel quite like and just overall uncomfortable. That being said, these are rather interesting. I will certainly keep a look out for them, and maybe revisit in ear earphones.
These are very tiny and do not insert deeply into the ear canal as do such types as the Etys. Although none of the included tips fit my ears, the tips from an old set of Head-Direct phones fit just fine and achieve a really good seal without extending into my ear canals. Because of this, they are quite comfortable and due to the very light weight, they "disappear" almost instantly leaving only the music.
I have contacted Fang and asked him for the specifications and when the RE-600 will be released for sale.
He usually is prompt with his replies and I will post the info as soon as I receive it.
