Yeah, they're really good. At first try they did sound a bit flat even for Sennheisers, but they've warmed up nicely over the past few days. I've loved Sennheiser's more natural sound signature ever since I got my first CX 400 earbuds a decade or more back, and I've been longing to get something really good for quite a while. I've been drooling over HD 650/HD 6XXes, but they're too pricy by far. She definitely made an excellent choice in finding something very good that doesn't require a mortgage to afford
I'm running them off an Optoma NuForce uDac3, which is plenty good for me (and small enough to have taped to the underside of my desk, completely invisible).
I doubt I'll go bonkers for audio, as I'm kind of allergic to audiophile BS. I worked in an electronics retailer while I was a student, and we got bought up by a high end audio chain. Half of the training stuff they made us go through was ... ineffective, to put it mildly. I mean, there was
a lot of great-sounding stuff we sold, but I will never, ever believe in the value of $500 USB cables or $1000/m speaker wire. There were some very expensive speakers and high-end amps that did sound very, very good - but there were plenty of inexpensive speakers that sounded very good too, and low-end amps with surprising sound quality. So I'm pretty firmly in the "I want good sound, but I don't believe in
magic ghosts things I can't hear" camp. And I'm not rich enough to go crazy
