Got mine yesterday (about 56 days from date of ordering). They arrived in good condition; the box was a bit beat-up at the corners, but the headphones were in good condition, and I didn't detect any defects. They also arrived with the foam cut out of the middle; I was kind of relieved, because I didn't want to have to make that decision myself
.
Was able to listen to them for about 10 minutes before I had to go get my wisdom teeth extracted. Naturally, I wasn't feeling very well post-op, so that was the extent of my listening yesterday. I'm listening to them right now, and have been doing so for about half an hour. The first thing that struck me about them is the astonishing, deep, velvety bass. It's some of the best bass I've ever heard from headphones, and certainly the best I've heard from open headphones. The bass is really something, but it is also very well-behaved; there's no bleed into the upper registers, as far as I can tell. I've owned the DT 990-600s twice in the past, and they're the nearest competitor, in terms of sound signature: bass-heavyish, open cans. And based on sound quality alone, I prefer the Fischers, no small feat for headphones that retail for a third of the price and can be found online for about half the price of the Beyers.
Another advantage of the FA-011s, IMHO, is the treble region. The Fischers still have plenty of sparkle up top, but it's not fatiguing or offensive, and it's probably a bit less sibilant, as well. I would describe the Beyers as dark and piercing. The FA-011s are warm, too, but this warmth doesn't overshadow the whole spectrum, and the treble is superior.
Save one caveat, I wholeheartedly recommend the FA-011s, for the Head-Fier on a budget who likes the sound of the Beyers. That one caveat is that the Fischers aren't very comfortable. After about 30 or 40 minutes, I already find myself working to place them in a more comfortable position. This doesn't bode well for long-term listening. It's kind of expected, though, coming from my K601s, which are lighter, have deeper earpads, and clamp less. So, in sum, based off about an hour of listening, I'd give the FA-011s an 8/10, and would probably raise that to a 9 or 9.5, were it not for the comfort issue. I will probably decide soon whether I want to keep them or not, but my hat is off to Fischer, for making a fantastic-sounding pair of headphones for a ridiculously low price.
