I have Etymotic HF5 for one month now and listening to it 4-5 hours everyday. Although I like the over-all sound, but when compared to my broken RE0 (right ear stopped working) I still prefer the later.
IMHO REO is a very enjoyable IEM compared to a slight boring sound(flat detailed) HF5.
Newbie here and i cannot yet described audiophile terms. What I love about REO are treble extension, timbre and has more air plus noticeable better vocals compared to HF5.
I wanted to purchase another REO from Head-Direct but i'll be more careful this time. I hope fellow HEAD-FIer will inform us here that if they have new batch(2012) of REO, it does have the strict build quality standards.
Im from the Philippines and if I shipped back a dead REO i will cost me $68 plus the cost of shipping it back here.
Maybe the great Clieos have an idea. Many thanks...
