I have a pair of AKG 171 Studio. I know these are not the best home-listening headphones, but I bought them because they are fully closed and they dampen most external sounds (for listening to music riding trains and stuff).
I have already used AKG 271, 141 and Beyerdynamic DT-990 headphones for some voice-recording at work, so I kind of know what to expect from these - let’s say I’m half experienced with headphones.
I’d say the AKG 171 is quite okay for listening at home, yet I think I need to get some half-open headphones at some point even if it’s only for comfort (the 171 have quite some pressure on your ears… really unpleasant over time when you’re wearing glasses like me)
Of course the amplifier is really important as well. I’m using a Yamaha AX-397 stereo amplifier - quite a good deal, low price and relatively high fidelity sound.
I’m usually listening with a pair of quadral KX-150 speakers, a few years old but still good 3-way speakers (100W @4Ohm). The room they are currently in doesn’t do them justice - I really need to dampen it down a bit.
Back to the initial question: I’m using the AKG 171 studio as my home-listening headphones, but I think I’m going to buy a pair of AKG 242 or something similar in the near future because it will offer a slightly higher listening quality with a lot higher wearing quality.
