The review of the Audéo earphones by Martin/dfkt on anythingbutipod is truly excellent (thanks!). I have bought the Audéos a week ago and used them intensively ever since. I find Martin's description of the earphones and their sound signature to be very accurate. Let me just add a few comments. While the sound with the black filters is much as described in the review, I find the grey filters to be virtually unusable. They make the phones just too bright. Even with the black filters the level of detail in mid to high frequencies is on par and even higher than with the Etymotic ER4S. For some type of music I felt inclined to reduce treble intensity above 9 kHz by up to 6 dB (on my rockboxed iPod). On the other hand near perfect live recordings like “A fortnight in France” by Patricia Barber, “Are we there yet” by Sara K. or the live part of “Hell freezes over” by the Eagles come to life in an almost shocking and frightening way! Guitars and cymbals are to die for and spatiality is clearly improved over the Etys.
The supplied silicone tips work pretty well, the one pair of complys that comes with the Audéos was, however, too small for my ears. I’d warmly recommend using Shure black foam sleeves on them. These have to be widened slightly for mounting but after that they sit perfectly tight on the nozzle. The black foam tips - for me - give better isolation than any of the supplied sleeves while remaining perfectly comfortable. Comfort of the Audéos is really good. They are so light and their shape fits my (pretty large) ears so good, I forget about wearing them soon after having put them in place. As Martin stated, keeping them on while sleeping in bed is not that good an idea but apart from that their fit is in fact almost perfect.
