So, I'm pretty much an audio noob who just bought his first set of headphones and I seem to have either misunderstood something or I've been scammed.
The thing is, I bought a pair of Beyerdynamic DT880 600Ohm headphones and ordered a Schiit Magni + Modi at the same time. Now the headphones arrived a few days ago while the company that imports the Schiit stuff is still processing my order, so I thought my 600Ohm headphones would be useless until then.
Of course I couldn't resist trying them on and just plugging them into my laptop (Lenovo Thinkpad E520) just to see what would happen if I tried listening to stuff without an amp and how impedance would effect the experience. Now, from what I read online (mainly here) about 600Ohm impedance I expected to hear nothing or a very soft sound at best, but to my surprise they worked just fine... Even when plugged into my old MP3-Player the only complaint I have is that the sound is a bit distorted, I believe some cheap Sennheiser headphones I have sound less loud than the DT880's do at full volume.
I immediately thought they send me the wrong version of the DT880's, but the box says '600 Ohm' everywhere. There is even a big silver "600 Ω VERSION AUDIOPHILE MODEL' sticker on the box. Then I checked the headphone-jack and there is definitively '600 Ω' engraved in there.
Someone thought it might be because the DT880 are fairly sensitive (96dB SPL), even though they have a high impedance. he said this causes them to only need around 0.4mW or 0.489V to drive them to 90dB or 12.58mW and 2.74V to drive them to 105dB, which isn't that much. Could this really be the answer?
tl;dr: My 600 Ohm DT880's sound just fine even when plugged into my laptop audio-port or old-as-F Sony MP3-player.
So now my question: Is this very strange and have I been cheated somehow or am I just a huge noob who doesn't get impedance?
Thank you in advance for putting up with my audio-noobness.
My dt880 600 ohm which I'm pretty sure are real :D
My friend INSISTED in plugging it into his galaxy s3. There was sound...albeit the sound was REALLY REALLY WEIRD..volume was ok though...think of bee gees singing even higher than he usually does.
That's my pitch.
